Collection_163. ETK_63_Headlights (part 2)

So the ETK section
Lighting devices

There are two types of headlights for the E30:
Before the restyling - ordinary headlights.
Details of a free-form headlight


After restyling - headlights with lenses.
Ellipsoidal Headlight Parts


They are structurally different and their parts are not interchangeable. But the headlights in the assembly are interchangeable. The difference is only in the wiring connectors.
Headlights come from two manufacturers - Hella or Bosch. The pre-88 low beam restyling headlights are not significantly different. After 1988, an additional cutout in the reflector mask appeared under the lens. The headlights of both manufacturers are interchangeable in terms of fastening, the connectors are the same.
Clear or yellow glass was available for each type of headlight. Also available for both types was a hydrocorrector of the angle of inclination of the dipped beam headlights, and a headlight cleaner.
I'm not sure, but I read somewhere that after '87 lensed headlights were available for early model E30s as a retrofit kit. I did it myself a long time ago - I bought restyling headlights with lenses, and replaced the headlight connectors in the main wiring.
As an aftermarket retrofit, headlights with Hella Black lenses were available - with the effect of dark optics. I made similar headlights myself.
Accordingly, in the following we will talk about such headlights - restyling headlights with lenses, a Hella Black analogue, with a hydraulic corrector and a headlight cleaner - the top configuration of headlights.


Part #1 - left (63 12 1 386 407) and right (63 12 1 386 408) high beam optical element - 2 pcs.

Part No. 4 - diffuser mounting ring (63 12 1 373 529) - 4 pcs. Headlight rings are silver. The same for all types of headlights. Optionally, they are chromed (fit with E32 or E34). For Hella Black headlights, the rings are black.
For headlights with a headlight cleaner, all four rings are different and have brush stops. The rings are numbered.

Part No. 4 - mounting ring of the left main beam diffuser 03 (63 12 1 385 591) - 1 pc.

Part No. 18 - connecting part (51 71 1 942 084) - 1 pc. Plastic insert in the left headlight shield for the air filter nozzle.
Part No. 19 - sealing ring (63 12 1 386 641) - 2 pcs. It is unreasonably expensive, I replaced them with a universal seal. Just like the gaskets in the headlight covers, which are not listed in the ETK at all.

I don't know why, but the clips for fastening the protective shields of the headlights are in a separate section of the ETK.
Ellipsoidal headlight details

Part No. 20 - locking mechanism (51 71 1 916 197) - 4 pcs. Headlight shield mounting clip.
Part No. 21 - lock insert (51 71 1 916 199) - 4 pcs. Headlight shield mounting clip.

Let's start with low beam headlights. We screw the lens to the body of the reflector. They are the same on both sides.


We screw the reflector with the lens to the left and right housing of the headlight diffuser with three self-tapping screws with a new gasket.


This mount has adjustment grooves for right-hand and left-hand movement. For right-hand traffic, you need to install the lens in such a way that the "eye" on the lens body points to the R/D mark on the headlight body (apparently this is an abbreviation for Right Drive)


If you want to drive your E30 to Great Britain or Japan :) , then after crossing the border, in order not to dazzle oncoming traffic, you will need to unscrew these screws, and turn the lens to the I/G mark - I don't know what this abbreviation means, but it is for left-hand traffic.

We insert the lamp without touching the glass with our fingers, connect the contacts, and close the lid with a new gasket.




We put on the ring. The headlight is assembled.


Similarly, we assemble the second dipped beam headlight.

It's easier with high beam headlights. We insert the lamp without touching the glass with our fingers, connect the contacts, and close the lid with a new gasket.




We put on the ring. The headlight is assembled.


Similarly, we assemble the second high-beam headlight.

All headlights are assembled. Now you need to install them and the adjustment screws on the plastic frames.


P.S.
I made several different colored sets of rings - black, silver and blue (the color of the car). I used to change them periodically ;)


It's a pity that there is only one set for the headlight cleaner. - with limiters for brushes. But maybe someday I will change it for variety! :)


Next, about the installation of headlights and adjustment screws on plastic frames.

Collection_163. ETK_63_Headlights (Part 1). Preparation and interesting experiments.

For some reason, I got a lot of photos of the headlights, so I decided to divide them into several parts.
In the first part, I will write about the preparation of headlights and interesting chemical experiments :)

So, a long time ago, I made an analogue of Hella Black headlights from ordinary Hella headlights. In my opinion, it turned out quite well. But over the years of operation, the appearance of the headlights has deteriorated a little...




So I decided to completely disassemble them again and bring them to their proper appearance. Cleaned and washed the glass, reflectors and lenses. New original seals are unreasonably expensive, so I replaced them with ordinary universal ones - they are no worse.




On the reflectors, the result of the same Osram Night Breaker +150% is slightly visible - spots and specks from overheating. Although, the reflectors were then re-plated with chrome.


Lenses


The main beam headlights were sanded, primed and painted.


Self-tapping screws and adjustment pins are galvanized.


My headlights have a hydraulic corrector. I did not disassemble the hydraulic drives (apparently they are not disassembled at all), so they remained ungalvanized. I sanded off their pins and decided to try to somehow protect them from corrosion at home.


I found a video about copper plating on YouTube - it seems that everything is simple and beautiful... So I decided to do these interesting chemical experiments! :)
I bought the necessary ingredients according to the "recipe" ;)

Copper sulfate - 100 g
Distilled water - 450 g
Electrolyte for batteries - 100 g


Prepare the mixture.
Pour copper sulfate.


Add water.


Then we add acid. Not vice versa! This is important!


We stir and get a liquid of a beautiful blue color. We carefully degrease the pins in a solvent or acid, and lower them into the solution for a second. And as a result of this chemical "focus" we get pins covered with copper!


It gets even better after a second dive.


But not for long... :) After complete drying, the coating became more like rust, and it was easy to rub off with hands! :)
So, the "trick" failed! :)
I had to re-sand the studs and simply paint them with zinc paint.


Now about the plastic threaded bushings for adjustment. For some reason, they are only available assembled with pins and plastic handles, and cost like gold! :)
Handles are different for low beam and high beam headlights. The pins also have different lengths.
I had as many as three types of pens.




The problem with the bushings and handles was solved thanks to a 3D printing friend of mine. Thank him for that.


Pin tips can be bought original or analogues. In addition to the two ends for the hydraulic corrector pins. They are available only in the original and are also not adequately priced. In the photo, there is a white sleeve at the bottom left. When I restore the operation of the hydraulic corrector, then maybe I will order them. Although, I don't understand what is the difference between them...
Well, the last of the preparatory work is gluing the protective transparent film on the headlights.


Now everything is ready to assemble the headlights.

Collection_162. ETK_63_Fog lights

A new MAHLE air conditioner radiator has arrived, but it is Made in China... What can I say.... I look at it and think that it might be better to install the old original radiator...? It looks much more reliable than this new Chinese one... Well, that's it... I was going to install the fan as well. Decided to check it again just in case...and it started jamming...sort of! Good thing I checked. I tried to disassemble it - the impeller stuck firmly to the axis... when I tried to knock it out, I broke it... :( It's good that a friend has the same fan, it's also broken - I'll try to assemble one of the two. Also, the record about radiators and air conditioning is postponed indefinitely...
For now, I will write about the headlights.
Lighting devices

I'll start with the fog lights.
Fog lights

On cars before restyling, there are two types of fog lights, depending on the type of front apron. By 1985, a "slanted" apron, and in 1985-1987, a "straight" apron. The difference is in the framework of fastening the headlights. The headlights themselves are the same. The glass of the fog lights could be transparent or yellow (for the French market).
So, in my case, this is a "straight" apron from 85-87 and, accordingly, headlights for it.



Some parts are not listed separately in ETK, and are assembled under one number. Here's how:



Part No. 1 - left (63 17 1 376 935) and right (63 17 1 376 936) fog light assembly - 2 pcs. Headlamp in housing, with wiring and with frame.
Part #2 - left (63 17 1 381 419) and right (63 17 1 381 420) fog lights - 2 pcs. The headlight in the case, with wiring and a bracket with a screw for adjusting the angle of the headlight.
Part #3 - diffuser left (63 17 1 375 067) and right (63 17 1 375 068) - 2 pcs. Headlight glass assembly with reflector.
Part No. 4 - halogen lamp 12V 55W H3 (63 21 7 160 779) - 2 pcs.
Part No. 5 - diffuser mounting frame (63 17 1 374 883) - 2 pcs.
Part No. 6 - self-tapping screw (07 14 6 977 197) - 4 pcs.

Part No. 7 - mounting frame (63 17 1 376 916) - 2 pcs. It comes complete with a rubber seal.

Item No. 8 is not used.
Part No. 9 - relay (61 36 8 353 447) - 1 pc. 5-pin relay (K8), black, similar to relay (K4) dipped beam and rear fog lights. It is installed in the fuse box, together with fuses #29 and #30. I wrote about it in the relay section.
Part No. 10 - shield (63 17 1 373 577) - 4 pcs. Plug in headlight mounting.
Part No. 11 - self-tapping screw ST4.8X13 (07 11 9 904 285) - 6 pcs.
Part No. 12 - spacer nut ST 4.8 WEISS (63 17 1 367 868) - 6 pcs.
Item No. 13 is not used.

The headlight housing is assembled with a diffuser seal, wiring and a bracket with a screw to adjust the angle of the headlight. I replaced the seal with a new one - I cut it from the same material. I installed the wiring and the bracket with the headlight angle adjustment screw.




Installed the lamps. By the way, about lamps. A few years ago I bought new original diffusers. I installed Osram Night Breaker +150% lamps in them. With these lamps, the headlight glass heated up very much. And after a few weeks, in the rain, when cold water from a puddle hit the glass, both new glasses cracked... So now I use standard lamps, without any "+100500%". Glass is not cheap, so I am not ready to buy new ones now. I left it as it is, with cracks - the reflectors are new, they shine well.


The glass is installed - the headlight in the housing, with wiring and a bracket with a screw for adjusting the angle of the headlight (No. 2).


We install plastic clips in the front apron from the inside.





We insert the rubber gasket into the frame, and fasten the headlight mounting frame with self-tapping screws.









But in my case these frames will not be used at all. I installed them just to keep them out of the garage. It's just a headlight fitting.


I already said that the fog lights were also yellow. I thought it would look good with the blue color of the car. I also decided to stick a yellow film on them. Additional protection for the glass, even though it is already cracked...



Standard lamps. Yellow protective film. It was necessary to do this right away, even then - maybe the glass would have been whole...


Another fitting.


The lights are ready for installation.


But I will install them not in the factory mounting frames on the front apron, but in the BBS apron. It provides for fixing headlights without frames. Here's how:


Looks nice, I like it! ;)


So, fog lights are installed.
And I will install the apron itself and the entire BBS body kit after I assemble the entire front end.

Next, perhaps, about the main headlights.
Or about the fan, if it turns out to be made of two ;)

Part No. 10 - clamp L15-19 (07 12 9 952 107) - 2 pcs.

Part No. 11 - hose 16X22MM (32 41 1 131 545) - 1 pc. The length is 0.5 m. The photo shows the old hose, because I lost the new one somewhere :) I have already ordered a new one again.
Part No. 12 - hose 12X18MM (32 41 1 131 524) - 1 pc. Length 0.5 m.
Part No. 13 - ring fitting (32 41 1 127 472) - 1 pc.


To make it more convenient, I screwed the hoses to the steering rack before installing the engine.
A high-pressure hose and a return hose are screwed to the rail.


Bolts and fittings have different diameters, so it is impossible to mix them up.


Oil tank, parts




Part No. 1 - tank for ATF lubricant (32 41 1 097 1640 - 1 pc. A filter is built into the tank, so it needs to be periodically replaced with a new one.
Part #2 - cover (32 41 1 128 332) - 1 pc.
Part No. 3 - sealing ring (32 41 1 128 333) - 1 pc.
Part No. 4 - bracket (32 41 1 126 321) - 1 pc.
Part No. 5 - bolt M6X16 (07 11 9 904 357) - 2 pcs.
Part No. 6 - elastic washer B6 (07 11 9 932 099) - 1 pc.

Part No. 8 - M6 nut holder (32 41 1 127 1860 - 1 pc.

We insert the lock nut No. 8 into a special hole on the body, and screw the bracket No. 4. As I said, I installed a dual vacuum brake booster from an AWD E30 325ix, so it shifted forward significantly. And now there was such a problem with the installation of the hydraulic power steering tank...


Fortunately, this problem turned out not to be critical, and was easily solved by slightly bending the bracket.


And the tank still stood in its place.


But a little higher than it was before. This is also not critical.


Now it will be a little inconvenient to fill and check the brake fluid level in the brake cylinder reservoir, but it is also not critical.


I haven't bought the hydraulic power steering pump yet, so I'll write about it later.

In general, the engine is almost completely assembled.




I'm waiting for the radiators, then I'll finish everything on the engine and air conditioner.

Engine with vacuum control system




Part No. 1 - air compressor of the exhaust gas neutralization system (11 61 1 284 269) - 1 pc. A plastic tube consisting of two parts.
Part #2 - non-return valve (34 33 1 158 1130 - 1 pc.
Part No. 3 - hose (34 33 1 153 977) - 1 pc.
Part #4, #5 - vacuum hose 12X19 (34 33 1 115 926)
Part No. 6 - clamp L18-24 (07 12 9 952 109) - 9 pcs.

I installed the hose on the vacuum brake booster a long time ago.
As a reminder, I installed a dual vacuum brake booster from an all-wheel drive E30 324ix, so the hose is on the other side and had to be shortened a bit.




We connect the hoses according to the ETK scheme. I immediately attached the throttle flanges to the hoses. They often fall out of the throttle body from old age. I put them on glue - I hope that now they will hold well.


We connect the hoses to the corresponding fittings on the throttle and to the corrugation and the vacuum brake booster. Between the hoses on the throttle there is another fitting - to it we connect the hose of the tank ventilation valve, which I wrote about earlier.


The vacuum hoses have been installed and are now positioned as follows:


Also connected to the throttle, and adjusted cables of the accelerator pedal and cruise control.

All that's left for me to do with the engine is the fuel injectors, radiator, and exhaust system.

I already mentioned the power steering hoses, so I will write about them next time.

Collection_159. ETK_13_Preparation and adjustment of the working mixture (part 2)

Air flow meter




Part No. 1 - air flow meter (13 62 1 286 615) - 1 pc.
Part #2 - cap (13 62 1 363 874) - 1 pc. Red plastic cap. I once had it, but then it got lost somewhere. It is still available for order, but its price is not adequate, in my opinion. That's why I just selected the size of the plug from the ones I had in the garage.
Part No. 3 - rubber-metal hinge (13 71 1 272 495) - 3 pcs. Apparently this is a bug in ETK. These hinges are not used on E30 with M20B25.
Part #4 - nut with washer M6 (07 14 7 134 319) - 3 pcs. Not used.
Part No. 5 - L-shaped idle control valve (13 41 1 286 065) - 1 pc. It is T-shaped (13 41 1 433 626). It differs in the location of the flanges.

Part No. 11 - hose (13 41 1 718 777) - 1 pc.
Part No. 12 - clamp L28-33 (07 12 9 952 113) - 2 pcs. Used only on cars after 88. But I decided to install them as well just in case.
Part No. 13 - rubber ring (13 71 1 272 494) - 1 pc. It is used only for heavy operating conditions (Heavy Duty). In my case it is not used.
Part No. 14...No. 17 - motor wiring connectors for the idle control valve and the air flow meter. I wrote about them in the section on motor wiring.

My air flow meter works fine, no one has done any DIY work on it, so I just cleaned it and painted it. And put the red plug in the adjustment hole.






Suction silencer. Filter Variable




Part No. 1 - suction silencer (13 71 1 726 965) - 1 pc. Plastic housing for the air filter.
Part #2 - replaceable filter element (13 72 1 720 861) - 1 pc. I use a BOSCH S9964 filter.

Part No. 10 - suction pipe (13 71 1 713 1280 - 1 pc.
Part No. 11 - snorkel (13 71 1 284 612) - 1 pc. In my case it is not used. An insert in the headlight cover is used instead. I will write about this in the appropriate section.

There is another version of the housing for the air filter - with a metal box, for heavy operating conditions (Heavy Duty).

Suction silencer. Filter Variable


In my case, only one detail is used from it:
Part No. 7 - rubber pad (13 71 1 312 328) - 1 pc. I do not understand why it is not in the previous section of ETK. A place for its installation is also provided on the plastic case.

We screw the air flow meter to the filter housing with four No. 8 nuts, through a No. 7 gasket and one bolt, which is not specified in the ETK.
We snap a plastic diffuser into the filter housing, which for some reason is not specified in the ETK at all. Install filter #2 and brackets #3.


We close the filter housing and fix it with staples.






We install rubber insert No. 4 on the spar, and insert No. 7 on the bracket.


I installed the idle speed regulator valve bracket on the manifold even earlier.


We install the filter housing in the grooves of the bracket and fasten with two nuts together with the cruise control drive bracket.
We install the corrugation and the idle speed regulator valve, fix everything with clamps. We install the suction pipe. We connect the wiring connectors to the flow meter and the idle control valve.


Next, about vacuum hoses.

Part #3 - fuel hose 6X11MM (13 31 1 272 750).
Item No. 4 is not used.
Part #5 - fuel hose 8X13MM (16 12 1 180 409).
Part No. 6 - adapter - 1 pc. For some reason it is not listed in ETK.

We connect the hoses with clamps according to the diagram.




But we connect it to the adsorber.


We fix the adsorber with a clamp on the fuel filter bracket, connect the tank ventilation hoses to the corresponding tube.


We fix the ventilation hoses to each other with a plastic bracket.


We connect the valve to the throttle together with the vacuum tubes. I will write about it later.

Idle control system ECU




On earlier versions, a separate idle control ECU was installed near the Motronic ECU. It is not provided for in my, more recent, motor wiring. So, from this section, in my case, only sensors are used. I have already written about them in other sections.

Part No. 13 - temperature sensor (12 62 1 710 512) - 1 pc. For instrument panel (brown on 1 pin)
Part No. 14 - temperature sensor M12X1.5 (13 62 1 709 966) - 1 pc. For Motronic ECU (blue on 2 pins)
Part No. 15 - oil pressure sensor (61 31 1 354 274) - 1 pc.

We install the temperature sensors in the thermostat housing and connect them to the motor wiring.


We install the oil pressure sensor in the engine block under the oil filter and connect it to the yellow connector of the engine wiring.


We lay its wire together with the wire of the crankshaft position sensor.


Next, about the air filter and air flow meter.

Collection_157. ETK_12_Engine electrical equipment. DME pulse sensor

So, the latest ETK subdivisions on engine electrical equipment.

DME pulse sensor




Item No. 1...No. 3 are not used. Instead of them, the torpedo mounting brackets shown in the photo are used to mount the ECU.
Part No. 4 - self-tapping screw ST6.3X19 (07 11 9 916 970) - 4 pcs. For mounting the ECU.
Part No. 5 - sheet nut ST6,3-1 (07 12 9 925 742) - 4 pcs. For mounting the ECU.
Part No. 6 - ECU connector housing 35 pins (12 52 1 270 971) - 1 pc. I have already written about all motor wiring connectors in the corresponding section.

Part No. 7 - pulse sensor (12 14 1 710 668) - 1 pc. Crankshaft position sensor. I also wrote about him before.
Part No. 8 - bolt M6X16 (07 12 9 905 536) - 1 pc. For mounting the sensor.
Part #9 - elastic washer B6 (07 11 9 932 0990 - 1 pc. For attaching the sensor.
Part No. 10 - bracket (12 14 1 710 747) - 1 pc.
Part No. 11 - wire holder D=12.8MM (61 13 1 267 476) - 1 pc.
Part No. 12 - bracket (12 52 1 711 227) - 1 pc. A bracket for fixing the diagnostic connector and the connectors of the crankshaft and camshaft position sensors. I have already written about him before.
Part No. 13 - bolt M6X12 (07 11 9 905 524) - 1 pc. Apparently this bolt is used for earlier brackets. In my case, it is not used, since the bracket is screwed with an M8 nut to the stud of the intake manifold.
Part No. 14 - spiral hose (61 13 1 363 375) - 1 pc. Plastic protective tube for the sensor wire.

So, I installed the pulse sensor at the engine assembly stage, so I simply repeat the photo of its installation on the engine.
Screw the sensor to a special bracket. We put a protective spiral tube on its wire. It protects against contact with the pulley.


We lay the wire above the water pump, through a protective plastic case.


We fix the connector in the bracket that is screwed to the intake manifold.


We connect to the motor wiring.


I installed parts #10 and #11 on the manifold stud along with the wiring and oil dipstick brackets.. Not sure if it's supposed to be that way but I couldn't find another place for them.


We fix the wiring in them.


Now, finally, about the interior part - installation and connection of the ECU.

DME

Part No. 1 - ECU DME (12 14 1 710 537) - 1 pc.
Several ECU options were available for the M20B25 engine. Most often it is Motronic 1.1 or Motronic 1.3.

I had two ECUs Motronic 1.1 (0 261 200 153) and Motronic 1.3 (0 261 200 173). Self-diagnosis function is available in Motronic 1.3 - I already wrote about it earlier. But for now I installed Motronic 1.1, because Motronic 1.3 was not working. I will replace it later.
I installed the ECU when I was installing the torpedo, so I'm also just repeating the installation photo.
The ECU is screwed to the torpedo brackets and connected to the motor wiring.


There we connect the white 3-pin connector of the tachometer and the economizer, and the black 1-pin connector of the air conditioner. The connectors of the automatic transmission remain unused, we fasten them to the wiring harness. Maybe someday I'll want to install an automatic transmission, then I'll connect them! ;)
The ECU is covered with a plastic shield.


So, all the electrical equipment of the engine is installed and connected.

Next, we go to the ETK section on preparation and adjustment of the working mixture.

[The_Glory]

Collection_156. ETK_12_Engine electrical equipment. Ignition coil. Starter.

Ignition coil




Part No. 1 - ignition coil (12 13 1 286 087) - 1 pc.
Part #2 - clamp (12 13 1 286 080) - 1 pc.
Part #3 - M6 nut (23 11 2 322 368) - 1 pc.
Part No. 4 - spacer washer 6.4 (07 11 9 931 044) - 1 pc.
Part No. 5 - M5 nut (07 11 9 922 038) - 1 pc.
Part No. 6 - spacer washer 5.3 (07 11 9 936 439) - 1 pc.
Part #7 - nut with washer M6 (07 14 9 156 628) - 1 pc.

We screw the coil with a clamp to the pin on the body. We screw the terminals of the motor wiring to its contacts. We close the contacts with a rubber cover.


The ignition coil is installed and connected.

Only the starter motor remained under the hood of the engine's electrical equipment.
Starter




Part 1 - starter 1.1KW (12 41 1 361 874) - 1 pc.

My starter had already been completely rebuilt before so I just cleaned and painted it.
Type N 0 001 108 018








Therefore, I do not consider the sections on its details.
Starter parts


Starter details


But I will say that, as it turned out, there are two types of starters. About this in the next section.

Starter mounting elements




Part #1 - bolt M10X75 (11 11 1 735 525) - 2 pcs.
Part #2 - elastic washer B10 (07 11 9 932 1220 - 4 pcs.
Part #3 - M10 nut (07 12 9 900 8120 - 2 pcs.

Item No. 4...8 are not used.

Part No. 9 - cover of traction relay (61 13 1 361 340) - 1 pc. Rubber sheet.
Part No. 10 - bandage L=292MM/B=4.8MM (61 13 1 377 134) - 2 pcs. Plastic screeds.


Never seen this original rubber cover on cars, but it is a very simple and effective protection against water for the starter terminals. The pad is put on the wire of the terminal, and fixed with two clamps. Everything ingenious is simple! (with) :)




We get such a "visor" over the terminals.


I tried it on the engine - a roof for the starter! :)




And now about details #4...8. Another inaccuracy in ETK. Bracket No. 6 is not used, and its fasteners No. 4, 5, 7, 8 are used - not logically. My motor just had a #7 bolt with a #8 washer. I got curious and found bracket #6 in ETK - 12 41 1 266 711. It is for M20 motors. So I decided to install it too just in case. :) I barely found it, cleaned it, galvanized it. I started to install, and here is the fiasco! :) It does not fit the size of the pins.


In addition, it does not fit the length of the starter!


There is no point in leaving it like that - it is not very convenient to screw the terminals there anyway.


Therefore, I removed it, and left the bolt with the washer as it was - as a plug.


And the whole point is that there are two types of starters for the M20.
"Reducer" - like mine.
And "without gearbox", - earlier.
So, this bracket is only suitable for a "gearless" starter. Now I know it! :)

The starter was installed after the engine was installed - it is not very convenient to do it, but it was installed. We connect the cable from the battery and the terminals of the motor wiring. The terminals are of different diameters, so it is impossible to mix them up.


Terminals under the roof. ;)


By the way, you can make the visor yourself - I removed the dimensions from the original one, if anyone needs it.


That's it for the electrical equipment of the engine under the hood - only its interior part remains. More on that later.

[The_Glory]

Collection_155. ETK_12_Engine electrical equipment.

I will briefly write about all the details of the engine's electrical equipment.
Earlier, I already wrote about the elements of fastening the wiring harness on the engine. Now about fasteners under the hood.

Fixing elements of the wiring harness (part 2 )




Part #1 - protective cap (12 52 1 279 703). Perhaps this is a mistake. I have never come across this detail on an E30 (photo from the Internet).

Judging by the photo from the Internet, it was used on earlier models with Jetronic.

Therefore, the part is not used.
Part #2 - protective cap (12 52 1 284 465) - 1 pc. This part is only used on early E30 models up to 1985, with the rectangular C101 connector which is fixed to the fuse box housing. This cover covers the connector C101. Photo from the Internet.


Since my wiring is later, the part is not used.
Part No. 3 - cover (12 52 1 286 052) - 1 pc. This is a red cover for the diagnostic connector on cars before 1985. Similarly with detail #2, not used.
Part No. 4 - protective cap (12 52 1 279 603) - 1 pc. Motor wiring relay cover.
Part No. 5 - bracket ( 12 52 1 279 602) - 1 pc. Bracket for mounting the motor wiring relay.
Part No. 6 - rubber sleeve (61 31 1 369 343) - 1 pc. This is a rubber sleeve in the washer fluid tank, into which the fluid level sensor is inserted. Why it is in this section, I do not understand.

Part #7 - connector holder C101 (12 52 1 710 729) - 1 pc. In ETK, for some reason, it is written that this is a diagnostic connector holder - this is a mistake.
It is screwed to the shield.

Fixes connector C101.


Wiring Plug Connection


I already wrote about these connectors in the section on motor wiring.

Part #1...5 - connector C101 assembly. I connect the motor wiring with the main wiring. Fixed in a special bracket on the left of the motor shield.

Part No. 6...9 - diagnostic connector assembly. Fixed in a special bracket on the intake manifold.



Another ETK section on motor wiring connectors.
Wiring plug connection


I already wrote about these connectors in the section on motor wiring. I have them all in good condition, so I did not disassemble them, and I did not replace anything in them. That is why there is nothing to write about.

ETK section on wiring fastening.
Wiring holder


There are a lot of different clips and clamps, and I can't imagine where they can all be used at the same time. Therefore, I also do not see the point of writing about it in detail here. I have already written about these details in the sections on different wiring harnesses. In the motor wiring, I used only a few of them - #1, 2, 3, 13, 14, 15, 17, 20, 22, 24, 25, 27.

Engine relay




There are also a lot of relays, but in fact only two types of relays are used in motor wiring.
Part No. 1 (No. 2) - relay (61 31 1 373 588) - 2 pcs. Fuel pump relay and lambda probe heating relay. It's the same 4-pin relay as the relay in the fuse box. Mostly orange. It can be yellow, brown, or blue. I wrote about it in the section on the fuse block.
Part No. 10 - relay (61 36 1 729 004) - 1 pc. Main relay. Specific 5-pin relay. White color.

All other relays are not used in my case.

Another ETK section on the fuel pump relay.
Fuel pump relay


Again some inaccuracy of ETK. For my motor wiring, the fuel pump relay is in the previous section. And all these relays are probably for earlier Jetronic models.
So, in my case, these relays are not used.

The relays are fixed on a plastic bracket that snaps onto the body bracket.




1 - lambda probe heating relay.
2 - fuel pump relay.
3 - the main relay.

Relays are closed with a plastic cover




So, that's it for the details of the engine's electrical equipment.

Now I will write about connecting the hoses to the engine. I already wrote about them in the relevant sections, so here we simply screw them to the installed engine.

Right engine cushion with heat shield. We screw the tubes of the oil cooler to the flanges of the oil filter adapter. Of course with new rubber rings.


Left engine cushion. Before installing the engine, I bolted the power steering hoses to the steering rack. I will write about them separately.


We fasten the interior heater hoses - the lower one for supply, the upper one for return.


I will write about fuel hoses later.


Next, about the starter and the ignition coil.

[The_Glory]

Collection_154. ETK_12_Engine electrical equipment. Engine wiring harness

So, the motor is installed, I also installed the wiring harness earlier - you just need to connect everything.

Engine wiring harness




Part #1 - engine wiring harness (12 51 1 711 212).




1 - Motronic ECU connector
2 - connector for connecting the tachometer and the economizer (before restyling)
3 - connector for automatic transmission, selector position (I'm not sure exactly)
4 - connector for automatic transmission (I'm not sure)
5 - connector for connecting the air conditioner (signal of increased idle speed when the air conditioner is turned on)
6 - connector for lambda probe
7.1, 7.2 - ignition coil terminals "+" and "-"
8 - "mass" terminals

9 - connector C101 for connection to the main wiring
10 - fuel injector connectors (6 pcs.)
11 - temperature sensor connector for the Motronic ECU (blue on 2 pins)
12 - temperature sensor connector for the instrument panel (brown on 1 pin)

13.1, 13.2 - starter terminals "+" and "-"
14 - throttle position sensor connector
15 - tank ventilation valve connector
16 - valve connector of the idle speed regulator
17 - air flow meter connector
18 - lambda-probe heating relay connector
19 - fuel pump relay connector
20 - main relay connector
21 - crankshaft position sensor connector
22 - camshaft position sensor connector
23.1, 23.2 - generator terminals
24 - oil level sensor connector
25 - diagnostic connector
26 - connector for connecting the air conditioner
27 - oil pressure sensor connector
28* - oil level sensor connector for OIL Level Matic (aftermarket, I added it myself)


So, the wiring goes through the motor shield on the right, into the cabin, to the Motronic ECU. There, connectors 1, 2, 5 (and 3 and 4 if there is an automatic transmission) are connected to it. I will write about this later, but now we will talk about its underhood part.
We screw the "mass" terminals to the right body strut, screw the terminals to the ignition coil, fix the wiring with clips. The lambda probe connector will be connected after the exhaust system is installed.


We put the harness in a special holder on the shield and fix it with ties and one clamp. We install the C101 connector in a special holder and connect it to the main wiring.


You need three such clamps in total. Two more on the intake manifold.


The first collar on the collector


I also placed the air conditioner connector here. By default, it should be somewhere near the compressor, but since I connected the restyling wiring of the air conditioner through adapters, I will have it here. There is no point in dragging it through the entire engine compartment.
The second collar on the collector.


We fix the wiring with clips to the oil dipstick brackets.


We connect the crankshaft and camshaft position sensors, install the diagnostic connector.




We fasten the terminals of the generator and its "mass" wire.


We connect the oil level sensor and screw the cable of the main "mass" of the engine to the pallet.




The air flow meter connector will be connected after it is installed. We install the relay holder, fix them there and cover with a plastic cover.


We fasten the additional "ground" wire of the valve cover (65 31 1 286 069). I made it myself - almost no different from the original ;)


Fuel injector connectors will be connected after they are installed.


We connect temperature sensors for the instrument panel (1 pin) and for the Motronic ECU (2 pins).


Next will be about connecting other electrical equipment of the engine, and connecting all hoses.

Thank you, I would like to do it sooner, but in the current situation it is difficult...

I totally understand yet cannot fathom...stay safe brother.

[The_Glory]

Beautiful! All of your hard work is really coming together nicely. Getting the engine and driveline installed is a big step, you'll have it running in no-time.

Collection_153. Engine installation

So, finally everything is completely ready and this day has come! :)
Since my garage is not very suitable for installing the engine due to the lack of a normal floor and a lifting winch, I had to do it in my friend's garage. The same place where it was removed from the car earlier. But, for this, first you need to somehow get that engine out of the basement... It has quite a lot of weight, so they pulled it out in a simple and ingenious way! :)


I drew my "x" on a sheet of metal along with a wooden pallet. It turned out quite quickly and easily!


But it was more difficult to load it into the car! But the four of us did it.


Now it was necessary to get the car out. It seemed that it was even easier, but it didn't work the first time. This is all because of the "reliable" Chinese towing cables that broke three times! It was not without "victims"... my "x" suffered a little - a metal hook flew right into the bumper grill... :( But it's good that it didn't hit the headlight, or the glass, or the radiator... And it's even better that not in the "thirties"!


After all, the E30 rolled out onto the street for the first time in several years!






Of the brakes, only the handbrake works, because the calipers have not yet been installed. Therefore, we slowly and very carefully drove to our friend's garage. It's good that it's nearby, we got there without any problems.


During the work, there was no time for a photo, so the result is already ready - everything is installed from below, except for the exhaust system.


The photo on the way home was a bit unsuccessful :)


The descent into the garage was also successful.
So, the engine, gearbox with clutch and cardan shaft are installed. It remains to connect the wiring and hoses.
But even so it looks good - I like it! ;)












This is some progress! :)
Now I'm installing all the parts under the hood - next time I'll write about it.
