[QUOTE="13fist, post: 1533002, member: 31010"] Finally decided to deal with old connectors, aged wires, and ratty looking tape & loom. This one from the alternator has been bothering me since I got the truck. The green rot goes back several inches. [ATTACH=full]177565[/ATTACH] While I've been collecting pigtails, wire, and fresh bits & pieces I was doing a lot of searching for diagrams, pin-outs, and what not. Everywhere I've read has said this main wire from the alt cannot be replaced. Turns out that is not at all true. Since I was replacing worn out GPCM connectors, I was going to have to deal with it anyway. [ATTACH=full]177566[/ATTACH] At least on my truck this is the only place in the wiring harness where this cable ties into anything. While I'm sure GPR truck are different, I can't imagine it being more complicated. [ATTACH=full]177567[/ATTACH] Once it was de-pinned from the connectors, it was completely free from the harness. Trading it for a run of 2ga and a mega fuse to replace the fuse links, and this was the easiest part. Still got ICP, IPR, & Valve cover connectors to do. I was originally going to finish everything up in cheap techflex split braid I got from amazon. It will work for some of it, but I didn't pay attention to the heat rating and it does get melty in places where it contacts hot engine. Gonna have to rethink that. This mess is a more time consuming job than I expected, but I should have it wrapped up later today and have more pics. [/QUOTE]
