Using Suburban under dash wiring in pickup cab???

[hrc200x]

I'm wanting to put my '86 suburban under dash wiring into my '83 pickup cab. The pickup frame has dual tanks, how hard would it be to hook up the switch? Also the Burban has power locks but not power windows. I'd like to find a '85 or '86 wiring harness for a pickup with power windows/ locks, and dual tanks. No junk yards around here has it. If I do end up using the Burban wiring how hard would it be to put power windows in?

Does anyone on here have a parts truck preferably '85/'86 that has PW/PL, dual tanks with a clean non cut wiring harness? If so I'd be interested in it and have tons of parts I could trade, or list a price.

Any other problems I might run into with putting the Burban wiring into a pick up cab? I'd probably end up using the Burban column also.
