Electrical wiring

Can someone please tell me the wiring diagram for a 1981 Chevy Suburban power window and lock system so I can install them in my 1975 C20 custom.

register at autozone.com and look up the repair manual for your truck. They might have the electrical diagram.

An after market power window and lock system is available which requires much less destruction to get the same result. Check the hot rod forums if interested.
