Is your truck 4x4 or 2 wheel drive? What year is the donor cab? Is it a 2 wheel or 4x4? Is your truck auto or standard? Whatwas the truck the cab came from?

mine is a 86 2wheel drive auto the other cab is also 86 auto 2wd. only diff is mine is the custom deluxe not sure what the other is it just has a light in the cab and on the back above the bed. an mine dont which is no biggie. im just nervous about all the wiring. im not going to keep a/c on this truck just a defrost/heater. and plan on doing the autometer gauges in dash while swaping
here is a pic of the truck before i start incase i dont get it back together lol jk

Keep the a/c if your new cab has ac

the new cab is completely bare ill jhave to transfer everything. i have a very strong built 383 in it now. runs high 12s only reason i still got the a.c compressor is for the serpentine belt setup. it will be gone before long. this wont be a daily driver seeing how it will be getting faster soon ;)

What is wrong with your cab? It looks pretty clean in the pic! Wiring is simple enough, its just a big harness under the dash. Unbolt the one center bolt under the hood that connects the engine, tail lights, & head light harness to the back of the fuse box through the bulkhead connector. You unbolt the fuse box from the inside of the fire wall and pull the harness out. There are a few grounds and plugs to undo. Swap it into the other cab and reconnect the three harnesses.

well when you open the door its rusted pretty bad an whoevery had it before me did some bad bondo work on the cab corners. the floor in the corner all the way up drivers side is rusted through you can see pavement lol the new one is awesome no bondo or rust an nice doors jus need to replace the weatherstripping an make manual windows instead of electric.

if the new cab had a/c then your heater/defrost box won't cover the extra openings in the firewall. and the heater core is positioned differently. i did the same cab replacement on my truck. i went from a custom deluxe to a silverado cab. i also went from a 4x4 cab to a 4x2 cab, so i had the cut the tranny hump and weld. trucks with a/c don't have the manual vents in the kick panels. the light in the back is the cargo light. painless harnesses are well marked, i would just remember how the factory wiring was placed and do yours the same way.
