Then isolated the stuff that had to stay. I found the OEM starter relay wire and connected it to a push button. Ignition hot to a toggle switch, which powered the gauges thru a fuse and the fan relay. I salvaged all the wire I needed from the car. Ignition switch is gone, and all I have in the car is the kill switch, a toggle switch, and a push button. Super simple and it was free and easy.
I guess I can't really say I'm going to tear out everything and start completely from scratch. I like your idea and I'd salvage more of what's there if it were in better condition, but the previous owner(s) have really made a mess of most of it. Basically I've attempted to identify everything in the engine bay with a wire going to it to determine whether I need to wire it up again when I'm finished. I've decided to keep the Duraspark ignition control setup, and the wires coming out of the duraspark box and going to the distributor and coil will mostly stay. I think I'll leave most of the factory headlight and parking light wiring in place to maintain the ability to be street legal, but I don't think I'll actually connect them to anything for now. The neutral safety switch and brake light switch will stay but get new wiring to my circuit board.
So much of the wiring that's there currently does nothing, as this vehicle originally had a "computer"-controlled idle speed control motor attached to the factory carb, and the prev owner swapped in a different engine and an aftermarket carb. The "computer" is still there and has a massive bundle of about 20 wires coming out of it and disappearing into the harness snake. There are many many loose connectors dangling from various points along the engine bay harness and not going anywhere. And then there are a bunch of added wires (like lamp cord wires) from previous owners, with exposed twist connections to random harness wires. These power the aftermarket electric radiator fan, aftermarket fuel pump, custom starter button (since the steering column is shredded), and probably at some point there was a stereo done the same way.
Anyway, it's a mess. Basically I'm starting from scratch, but with the exception of a few components that haven't been defiled by previous owners and don't really need any changes to perform their function in the new setup. There's way too much mess there for my tastes, for an electrical system that really only consists of about 10 components in the entire vehicle.
