The only thing left in the ignition system that I have not changed out is the green wire, plug wires, and ignition switch. At this point I really don't think it is the plug wires. The green wire is corroded pretty bad so is the focus for now. I hope after all this the problem is not in the ignition switch. If replacing the green wire doesn't cure the issue I'll jump the switch.

So this mystery wire is a coax. Interesting. I may unwind it and splice into the harness, unfortunately that means using some of the existing wire. Going direct to the box may be a better idea.

I knew what I was getting into when I bought this car. So far I don't have a lot of cash in the parts/repairs. It'll get sorted out and it will (slowly) become my daily driver. It's a really cool car that deserves a second lease on life. All this DIY troubleshooting also helps me with the fuel system side of our business as many times electrical issues are blamed on fuel and vice versa. When you're working with dilapidated fuel and ignition systems it gets tough to tease out the root of the problems.
