Won't start one day and fires up first crank next day

We have a non standard ignition system! This is not in the factory location or even Factory wiring!

What else may be hiding behind it? I will leave this to DEL!

Why Do Folks make this harder than that is needed?
Nobody makes anything harder. It's already harder than is needed BECAUSE THIS IS AN ONLINE DIAGNOSIS. I don't understand why there's a faction that always BLAMES people for making things difficult, when it already is. We're not in person! If you think it's so mofokin easy, then here's an idea. SOLVE IT FOR HIM RIGHT NOW! Otherwise, take your blaming BULLSHIT somewhere else! All everyone is trying to do here is help someone whose car we cannot even TOUCH. It's hard enough already, genius.
