Daily Driver s52 Sedan. The Silberbullet.

Alright so I am still lost on this whole fan thing...

What I know... my fan has a Positive (Blue) wire and a negative (black) wire. I have a 3 wire plug behind my drivers head light with a brown (ground) and a Blue/Black and a Black/Green wire running to it.

What I think I know... The Blue/Black is a 12+ positive wire.

What I need to know... What is the Blue/Black wire, what is the Black/Green wire and where do I put the "Auxiliary Fan Switch 2-Prong" and what wire does it run inline with?

Thanks for any help!

If you haven't already wired it. Drivers side headlight - Red wire (12v) to blue wire on your fan. Brown wire (Ground) to your black wire on your fan.

Passenger side headlight - Black/Brown (your brown wire, if you look closely it probably has a black stripe in it, its just dirty and hard to see) to one prong of your 2 prong fan switch. Green/Black wire to the other prong of your fan switch.

Use this switch: (61-31-1-364-272-82 ) with an 80 deg C thermostat.

This will allow your fan to come on at the correct time.

I figured out the throttle issue, 328ijunkie is correct on what he is saying. I also have the EVAP solenoid plugged in and plumbed but with no charcoal canister however. My list of things to do is becoming rather small. Hopefully will be driving it some on firday and more permanently at the start of this coming week.

I will check the ICV an make sure it is in all the way.

Im looking into Air Filter options, any suggestions? Maybe mod a stock air box so I can easily replace filters.

Will get PICTURES and a VIDEO soon!

Your last picture is the evap solenoid that is used for emissions. I left it off of my car - it will set a code but otherwise run fine. I believe a 1k ohm resistor can be used to keep a code from being set.

TPS plug goes into the throttle body that bolts to the intake manifold. I assume youre still running the ASC throttle body by the sounds of it (you dont need it). Nothing gets plugged into that. Throttle cable also goes into the main Throttle body. Your ICV in the manifold all the way?

+1. Sounds like your throttle body is either cracked open or the ICV is wide open/not plugged in.

UPDATE 7/9/2013:

The motor is up and running! But we are having idle issues, there are two spots for the TPS to plug into and 3 spots for a throttle cable. I know there is a cruise, ACS, and throttle cable, but do not know which goes where.

When we fire it up it idles for a milisecond and begins to rev out and at about 4k I shut it off.

What could be causing this and which is the throttle cable bracket?

I do not have headers, I will be utilizing the s52 manifolds, and the m3 muffler section with custom hangers. I think I am doing custom from the manifolds back due to budget.

[Cyrix2k]

Do you have headers already? I just put an exhaust on my M50NV swap car so I can help.

Update 6/26/2013:

I haven't got much done, but I only need to do a few things before I receive the harness and ECU Im waiting on. Exhaust is the biggest dilemma, any suggestions?

I got a buffer/polisher today:



Also found the other half of my fan harness, I am planning to run the stock radiator plug with the red wired to my positive SPAL wire, and the brown to the negative SPAL wire. I will see how this does for temp control. If it does not work well i will wire it like 328ijunkie says to and only utilize the high speed with the 80-88 temp plug.



And lastly anyone know what this is and where exactly it goes? It fell off my intake manifold.



Thanks! Wheels get here tomorrow!

Morning bump would like to get this sorted today.

Alright awesome, that is what I will do then. Thank you guys< i hope the Tb heater does not end up being a problem. We shall see.

I got my fan mounted today before going onto the lake, I will tackle wiring tomorrow I hope. Then just waiting on harness and ECU.

Problems.
On my phone, bleh

Sorry for not getting back to
You sooner but you've basically figured it out. The modded sensor I sell takes the place of the throttle body heater port on the head. You have to have an ecu coolant temp sensor. Your harness will come back to you with the obd2 factory temp sensor plug for
The ecu an modded to allow you to plug in the brown base single pole e30
Sensor as well. I wouldn't worry much about the tb heating. BMW as one of the few manufactures that implemented the tb heating for a while (mainly cause of plastic intake manifold not conducting engine heat). But I know of people up north running without it and not having any pr

I think 328ijunkie is Dave at MMW. You will delete your throttle body coolant lines, and place your new brown top temp sender in the hole in the head from the throttle coolant lines (you will remove the throttle body coolant plug.) You will then seal off the throttle body coolant port on the metal coolant tube. Dave should take care of the wiring.

Why can't you delete the lines? Emissions?

328ijunkie can you explain what you mean by my ECU temp sensor.. I don't know what you mean. I think I will send you a PM asking as well. I have tomorrow to work on my car, I plan to get my fan mounted, and work on some of the wiring for the fan as well.

EDIT: Just did some searching and found this... http://www.r3vlimited.com/board/show...ht=temp+sensor That makes me think that Dave at MMW will be sending me back my harness wired so I only need the e30 brown sensor..? Or I am confused because I can not get rid of the throttle body heater lines.

Any thoughts on the temp sensor?

EDITTT: So I have done some reading last night and this morning, and it looks like my only real option is to move the brown top sensor to the throttle body heater hose and replace the stock coolant ecu sensor back in its original hole, and I will have to take my chances with no throttle body heater... I live in Eastern Washington during the winters, but I do not sit in traffic ever when driving over there and from reading it seems as if when you sit at an idle is when ice can become a problem in the TB.
