    To compliment my last post, here are the wire colors from the ignitor unit. As you can see, there are no solid black, solid gray, or solid orange wires here. For my application I’m going to try to match the wiring colors to those coming out of the ignitor unit since this will be a point of reference for future troubleshooting. The diagram shows solid brown, solid white, and solid green wires as an intermediary harness. I think that’s an opportunity to improve and save myself future frustration.

    Is that your plug coming from a rectifier is there a way to test those rectifiers I’m having a charging problem now with my 1980 XS400

    It’s the plug for the ignitor unit. It’s the brains of the ignition system.
