    I am trying to figure out what round obd-to-obd2 (16pin) adapter cable to purchase, but I am unable to determine what port I have on my 1982 633CSI.
    Online all I can find is a round 20pin, while mine only appears to have 15 pins,.. see photo.
    Any help would be much appreciated.

    The 15 pin DMEs have no diagnostic abilities. Reset for services was the main use for it.
