    M50 swap extra connectors e30 harness

    Anyone have a quick answer what to do with the 4 wires that get unplugged from near the ECU on the e30 harness (325i). I do not see equivilents on the m50 harness.

    a) Blue/white stripe - single black connector
    b) Blue/red stripe - double white connector (only 1 side used)
    c) Brown - single black connector
    d) White, Green, Blue/black stripe - triple white connector

      I've always thought that was the C104, but I'm more familiar with eta's. Not sure if it is referred to differently for your car. It has the tach signal and fuel consumption connection you need if it is the same as the eta..

        okay - thanks - I came across another old post talking about 103/104 so keyed me into the 3 pin being that.....


        So ---- any help on the other wires? I have the wire manual and elec t-shoot guide, but can't figure them out.
