    a search should find you info on 5-speed wiring.
    I'm talking about reverse light wiring and a "neutral safety switch"

      yeah. it's all E30 body harness stuff. search for 5-speed wiring, or look up the diagrams in the ETM.

          So would anyone have any reservations about chopping off an X20 connector on a 1995 S50 and adapting a C101 for use in a 1990 325i using the following wiring diagram?





          And using the following for ABS Wiring:
          On the chassis side of C101 (big plug that connects the engine harness to the chassis), pin 20 (red/yellow wire) is ABS. I ran a 14 gauge wire between pin 20 on the engine side of my connector to the Engine Control Module Relay in the E36 engine bay wiring harness. I tapped into the red/white wire (Relay port 87a). This gives power during start/run.

            So I'm going to be cutting this harness tomorrow, any last suggestions, input, or warnings?

            EDIT: Or some reassurance that my wiring is right.
