    Default E37 Bench harness Pins

    Searched on the help- bench harness tutorial info, and didnt find the info for the E37, wich are the pins needed on a bench harness for the E37..

    im using 19-switched ignition, 20-battery, 73-switched ignition, 43 and 44 CAN signal on C1, on C2 73-ground, is this correct?? cant read a E37 ECM, maybe the ecm is bad. just want to check

    There are probably many ways to build a Bench Programming Harness for the E37. The PDF attached below is just one possible way to do it.

    I would use only the C1 / X1 / J1 connector (call it what you will) - similar to an E38 setup.

    I've tried this one and others on 3 different ECMs and can't connect to any of them. Any ideas?
