77 c10 wiring for doors

[MYBAD66]

hey there all just picked up a 77 c10 with power windows and power locks...but all of that is dissassembled. wondering if anyone has a diagram of the door I can go off of to wire the switches up? I have an extra wire on the switch from the door. and when a probe is used all the wires on the door ground except for one wire that gets nothing. i'm good with mechanics and logic buuut electrical is very much something i'm not good with. any tips and tricks will be appreciated!
