    ECU Pinout and Mil-Spec Part Numbers

    Not sure if this is in the right section but if it's not then please move.

    For those of you who are interested in building or just fixing your harness, here comes the thread with knowledge I collected from vast information on the world wide web. This is not my due diligence as I just compiled the list. Credit goes where credit is due.

    Disclaimer: None of the part numbers are Honda part numbers and you will not find it from them.

    You only need A,B, E for Manual. C, D are for Automatic ECUs

    A and B is on the engine harness
    E is on the dash harness
    C, D on automatic dash harness

    31 PIN A: 1318682-6
    24 PIN B: 353029-1
    22 PIN C: 353028-1
    17 PIN D: 353027-1
    31 PIN E: 353826-1

    again A, B, and E are just for manual.

    Mil-spec Circular Connector for the die hards

    Credit: ummmm not sure just kinda looked at pics and found it lol

    Disclaimer: There are literally 1000s of pages of different Mil-Spec Connectors that all look familiar, I really suggest you learn the difference in the part numbers before making an order. There are guides that explain them and if I find the link i'll post it. This is a very common connector which is why I posted it.
