Hello all! I am currently working on an 82 f150 with the 5.8 351 Windsor. The motor itself is good and runs great but all the wiring under the hood has been chewed and torn up. Would love to get it rewired and cleaned up a lot! I’m needing some pictures and diagrams of engine bays and harnesses under the hood so I can get everything as close to factory as possible. Also interested in any suggestions you have! This is my first truck I’m planning on restoring.
Note the 98% or the engine bay wiring is part of the trucks main harness that runs across the top of the dashboard.
The ALT has a harness that is not part of the main harness as is the DSII IGN system harness.
If you have AC That is not part of the main harness also.
Also besides 300 six and v8 engine bay harness difference there is a different between single and dual tanks, EFI or carb and in tank electric pumps for the main harness
So depending on what all was eaten It might be best if you can find a v8 engine truck for the engine bay side of the harness and splice it onto yours.
I would think the wire colors would be the same or pretty close.
Just my .02

It's unsightly but it looks like you have rodent issues. Head over to a discount or bulk grocery store and get a BIG canister of Cayenne pepper. Sprinkle this around and under your engine compartment. This will stop the little cheese thieves quick. It will stop further wiring damage while you repair your truck.
I'm not sure if LMC truck has wiring harnesses, but you can look there.
FWIW, I keep a Tom Cat mouse block under the seat and one behind, under the battery tray. I also have them around the house, sheds, garage, basement. No more rodents running in or around my toys.
Get you truck running well, maybe you don't need to do much to the body... Oh, check out Hagerty Insurance, might be chaeper than normal auto insurance. I valued my truck low and don't drive it much. Under $300, for the year.

Any of the rewire harness kits you find are not for our trucks (universal or Chevy) and would take a lot of work to rewire the whole truck.
This is why I said to see just how bad the wires are in the engine bay and maybe find wires for under the hood for another truck (junk yard) and splice them in.

I just got my new LMC parts catalog today. (Wheee!!! ) It's lists "Painless Performance" wiring harnesses. You can check those out, either through their site or the Painless web site.

Unless they have made a new product line, the Painless harnesses are just universal hot rod wiring. Nothing will plug into the original Ford components. If you have to splice all the old connectors in place to plug into the Ford components, you might as well repair what you have.
No experience with this company, but their wiring kits look to be vehicle specific, unlike the universal hot rod kits offered by others.
There is a program on TV called "Wheeler Dealers" where they refurbish old cars. It varies where they do it. I've seen places on it that do custom restoration harnesses. It's done by hand to factory schematics but you can add other stuff too. I can see it being $2000 easy.

That would be the "universal kit" that they take the car / truck plugs off and re-pin them with the new wires so they plug back into the factory parts.
They are also use to re-wiring as they live across the pond in the land of darkness = Lucas wiring & electrical also known as the Prince of Darkness.
I stll think I would look for a factory truck and cut it's harness and splice it into my truck as it should have all the right color wires and plugs.

Has the OP called local auto parts stores and asked them what they have for a selection of pigtails ? I recall a catalog that had a ton of them in the past.
A google search may turn up electrical wire pigtails for a ______ too...
