    m42-b35 wiring. anyone have the pinouts?

    Once again, I suck at wiring so if anyone has this already done and written down I would be very grateful. e34 harness.

    Alright after about half an hours searching I found this diagram that has all the 318is c101 pins.



    I know I wrote down the e34 stuff when I did my last swap but I have no idea where it is. If I manage to find it I'll be sure to post it up.

      Check out one of my wiring threads, I am pretty sure it's in there.

          Upon further inspection, all the pins are the same lol. This is going to be simpler than I thought :)

          Lets hope the e34 harness will plug into the e30 side.

            Depends on the build date of the e34 it came from....early ones were 20 pin, and later ones were 25 ;)

              Yup, I've got the 25 pin lol. Do you know if the pin arrangements are still the same as the 20 pin?

                  So what I see is:

                  318is 535i
                  hooked to:
                  1 - blue -alternator 25 - blue
                  2 - x
                  3 - x
                  4 - brown/white -ect
                  5 - brown/green -oil pressure switch
                  6 - green/yellow -O2s relay power
                  7 - green -dme power from ignition switch 21 - green
                  8 - white
                  9 - black -engine speed for tach 20 - black

                  13 - green/violet -fuel pump relay 13 - green/violet
                  14 - black/white -road speed signal 14 - black/white
                  15 - black/green -signal from starter to unloader relays
                  16 - white/black -pin 6 diag.
                  17 - x
                  18 - black/yellow -ignition switch
                  19 - x
                  20 - red/yellow -abs


                  Am I right? I feel I missed a bunch of info in that post but...



                  I think I'm just going to go to a junkyard tomorrow morning and grab me a 20 pin m30 harness. For my skill-set that sounds like the easiest thing to do.

                    Since I was in the middle of building a 25pin x20 to 20pin c101 adapter, this should help you:
