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.
