    My initial thought was that it swapped between the two HI/LO Fuel/Ignition tables - I could have sworn that they had slightly different values in them, but looking back now, they seem to be duplicates of each other. Any insight you can provide will be great!

    Because different people reference each pin in different ways, this diagram refers to pins in both the wiring diagram format (absolute pins ie. 52) and by connector (C2).

    In addition to that, I've also added the following;

    1. A basic description of each pin to help diagnosis of faults
    2. Where possible, additional uses for some pins, these are described at the bottom of the diagram

    If anyone feels there's missing information or sees an error, please don't hesitate to let me know and I'll update the diagram
    Thanks a lot Jason.
    Warm greetings from Indonesia.
