Electrical wiring

[Rawze]

As far as the wire looms go, I would just inspect wiring and replace the split-loom wherever it was going bad + ensure it is somewhat sealed form collecting moisture, unless there were issues.

If you wanted to go all out, you could remove the whole harness and do entire thing with it off the vehicle, then re-install it.

BTW: I replaced my dual (+) and dual (-) '1/0'-gauge starter wires (they were going bad form corrosion, etc. ) with a single 4/0 red and black welding cable for each and the starter works better than it used to. - Have helped a few guys do the same since. -- https://amzn.to/3a50Gxx
