    I got this msd box in some other parts and was trying to identify it. I called msd with the part number and they did not know what it was. At that point I was asked to email pics and after some time I receive an email back that it was 33 years old and that they had no wiring diagram for it. They also said the man that designed it for them had been retired for over 20 years. So my question is have any of you seen this box and by chance know how it wires? It is new and has never been installed, but the instructions were not in the box. thanks

    Black is ground

    Red is positive

    Orange is positive terminal of coil

    violet and green are magnetic trigger pick ups

    white is point circuit


    Looks like basic MSD wireing to me. DOnt use Violet and green and white together.

    One black lead seems to be missing. Maybe the case gets grounded instead?
