I have been working on a wiring mess, and I finally got it all figured out. Holy balls, I have never seen so many useless wires ran to whatever the heck they were doing with them, toggle switches all over and breakers, burned up wiring, melted casing on wiring....glad this baby had no engine otherwise I would have probably tried starting it and burned the damn thing down!!
Since I suck at taking "before" pictures I do not have much, I like to jump in and keep going until complete and neglect before pictures which sucks because this was not fun.
Very thankful I purchased the green 76 GMC parts truck that was never touched, between that truck, the wiring diagrams on this site, and the 77 book you see in one of these pics, I got it done!
(As you can see, I am not too worried about cleaning everything up, I can do that later. For now I want it all to work properly).
Here is a small glimpse of the mess prior.

Here is some of the useless wires that were in place. Lots of wires spliced into others, bad crimps, poor connections...etc.

I now have all the wires routed properly (well, until I stuff the Olds engine in there), and all wires have proper ends on them, and as you can see blue tape with sharpie marker of where each wire goes. Put on new wire loom protectors also. Now I just need to fasten them into place with the plastic clips. I won't do that until the engine is in place in case I need to make small adjustments.

Got the AC stuff in it (old stuff was all cut/hacked up) from the green 76 and put into this one. Fixed up the wiring to get it all into place! (77 truck book, man is that handy!!). Got it all sealed up, every "correct" fastener into place..etc. Oh, and you can see the "properly" routed wires, nicely done and not just hanging all over heck...

And once again, glad I have that green 76, the headlight harness was ran along side the hoses you see on the fenderwell in that clamp, and of course all the plastic wire loom holders were missing, so I lucked out again and the green truck had all those little trinkets I needed.
See the fire extinguisher bracket, for how this thing was wired up I would have put one in there too!!!
