Your wiring

All home made except the harness between the tail lamps.

Wiring is intimidating. I would love to learn more on how to replace. I'm presently reinstalling everything under the hood from a rebuild and repaint. There are so many unused connectors from past emissions stuff (and who know what) that its confusing to know whats it for.
 
I pulled all my original harnesses out and went through them all in 1993, replacing anything coroded, burnt, sunbaked, etc. I’ve added so much in the way of ignition, ammeter bypass, trans brakes, overdrives, widebands and now EFI, that it’s time to abandon the factory wiring and go aftermarket everything.... it’s all coming out.

old red dodge you gave me the red x why may i ask
 
I diagnose prototype wiring and do harness repair at Chrysler Engineering. This stuff is cake. Much easier than repinning a 105 terminal module connector while it's still buried in the car.

I am not having any known wiring issues, EXCEPT for the wiring that is around the base of the steering column in my 70 Roadrunner. There are a couple of white plastic terminals with about 8 or 10 wires in them. I have had the gauges cut off and I had to "jiggle" that connector. It looks like someone cut all the wires on one side of one of the connectors and butt spliced them back together, keeping the plastic connector in the circuit.
I'm having a Dakota Digital gauge system installed so I'm not too concerned, but I do want to have the grounds of the electrical system checked, and maybe add a couple of engine/chassis grounds to be certain that grounding paths are well established.
 
My cars wiring are combination of original, and custom. Anything new that I do, I use crosslinked polyethylene wire (TXL/GXL/SXL), and stay away from the common PVC (GPT, or "hook-up") wire that many autoparts stores carry.
 
I put in a new wiring harness for the engine bay and front end. The rest of the car had original wiring - have to admit that always bothered/worried me a bit. I hope the new owner swaps out the balance of it. Wiring always intimidated me and I didn’t want to mess with what worked fine. Thought the engine bay was most critical so when the motor was done so was the wiring.
 
I Spent all day today re-wiring (part of) my friends '66 Plymouth Fury today. There is still more to do, but made all new engine harness, and fixed/cleaned up most of the firewall forward wiring. Under the dash there is still more work, but it is running now. It looks like maybe the amp gauge or alternator shorted out, and judging from the damage, not sure it had a no fusible link? The main power wire must have burned up from the neutral safety relay to the alternator. I think the previous owner replaced it with 16 AWG wire? Maybe 14 AWG at best, and did not clean-up all the other wires that the main one melted into. Had many butt splices with bad crimps that were held together with the electrical tape everything was wrapped in. Removed the tape, and wires were falling out of the crimp connectors.
 
Wiring on my 65 Belvedere is all custom. Schematics shown in pictures below.
I could NEVER have done this wiring job...way above my pay grade..lol
Heck it is even wired up for the 4-WAY FLASHER to work in case of emergency...maybe if the car goes dead 1/2 way down the track...lol, again.
