    includes all engine wiring, relays, ect.

    Complete with 3 relays, out of my 89 325i 5speed car. Only a single wire is cut, and it's the one going to the engine sensor on the passenger side near the front. The wire itself is long enough where all you would have to do is crimp or solder to the other end of the sensor.

    $50 shipped USPS priority mail.

    This came out of my 4/89 325i 2 door manual. Not sure how it's different from a 90 325is, beats me. Also had a 173 ECU on it if that helps.

        I believe the C191 is the same exact 7 pin plug. That's weird that it doesn't fit! I have a 10/88 harness and it has the C191, and the car came with a 173 DME.

        For airbag cars the ABS is powered through C101 pin 20, that's about the only difference I can think of between airbag/non-airbag wiring harnesses...
