I be got the same issue with my XS2 restorationAll right!! I think I finally have it.
So what I said about hooking up the wire's like in my last pic was indeed wrong. This is where guy's are taking their wiring apart, like me, and just matching up the color's, then realizing they have some left over safety relay wire's to deal with.
But now,, I THINK we finally have the correct way to do it. Thanks Jerm!! You da Man.
Please tell me this is correct. Then I can move on to the headlight bucket.
