    Looking for M42 wiring harness diagram or map

    Im doing this from the ground up so I have no reference point. Ive found about 80% of the connectors, but Im missing a few. Primarily the 2 plugs after the temp switches (one is a 6 pin connector)

    Behind the harness Im missing a few too. I could take pics or if anyone has a diagram that'd be useful.

    Ive been googling for awhile and I cant seem to find useful photos.

    the haynes manual has all of the diagrams

    or you can try this but I couldn't find one for the e30 m42, just the e36 m42

      I didnt think of the Hayne's manual for this application. The wiring diagram for the E36 M42 is excellent but the one for the E30 M42 is pretty poor in comparison.

      Unfortunately the harnesses are wildly more complex for the E36 than the E30 but maybe I can reverse engineer it and throw out the excess.

      First Ill start with Haynes.

        Try the earliest 318ti as a starting place.
        Just the dme sections- for the rest of the car,
        use e30.

        I don't remember ever seeing e30m42 BMW diagrams...

          Try this one. The 1992 318iC was an e30.

              All E30 diagrams are there. The 1992 one is the complete M42 relevant one.

                  BMW even admits that the 91 318 ETM is not final....cover says preliminary edition.
