    85 eta to latemodel c104 Glovebox ECU connector options

    So I'm doing another 327i turbo build this time the ECU 3 pin connector isnt compatible with the body harness. Anyone have a diagram of which wires connect to which or what I need t do to get the car running?

    can anyone confirm that this will work?
    Pin 3 from c104 to pin 8 on the c101 of the 89(yellow/white or white/white wire)
    Pin 2 from c104, run a wire directly to the + terminal on the coil (green wire)
    Pin 1 from c104 to pin 9 on the c101(black wire)

      What I did was take the C104 Connector from the engine harness from the Eta and splice it into the 325i Engine Harness. I used this as a reference.

      Let me know if you want me to go take a pic of my current setup. I've been meaning to a good writeup. It's pretty straight forward with both harnesses in front of you.

        Just wanted to update that all you need to do it wire pin 2 on the c104 to the Coil and the car will fire right up:)

          And make sure that pin 20 on C101 isn't hooking a red to a green...
