I have a 2000 ultracab 379 that originally came with a 63” stand up sleeper on it. I bought it as a day cab, but just got a 48” standup bunk off of a 2005 379.
My question is, where could I find wiring diagrams/wire numbers to get everything working? The plugs are different, and the labels aren’t legible. Local Peterbilt dealer (Hunter) are telling me they can’t find anything.
Heater + a/c controls, speakers and lights. Really can’t be that difficult, just looking to take the guess work out if possible.
Thanks in advance
