Wiring or AC?

[PbFut]

If not having AC is acceptable for a while, I would probably redo the electrical if you feel it is at end of life. The factory designed fuse protection of the harness was acceptable for the time but it is marginal by today's standards if you are using all the optioned accessories of the truck. My 72 is fairly original and fully optioned, and I added more stuff. I needed to change things a bit for the electric fans and camper battery I added. It was a mistake in hindsight to use electric fans but that is off topic. I needed to modify the shunt wire from the main splice in the harness to the battery. I had to disassemble much of the front harness to do so. I will say that my harness was in remarkably good shape for its age, including the volt reg, horn and headlights. All I really needed to do to the unmodified sections was clean with simple green and contact cleaner. on the connectors. The result was better than expected making the front end look very original and clean The factory did not use adhesive electrical tape. It is simply a vinyl tape wrap. It is easy to find and use once you learn the end technique. You can use electrical tape but it will likely get gummy over time. If you decide to repair, solder all your joints. Use shrink wrap to protect the other wires in the harness, and then vinyl wrap the set for a factory look. If you have time it is very easy to do and way cheaper than buying a harness if you have the time. Harnesses arn't that pricey so if time is an issue, get a new one. Good luck. I had a decent feeling of accomplishment once I got it all figured out. Not having to modify anything will be a snap for you.
