Rebuilding a 74 C10 Short wheel base stepside. Using an 84 cab. Nearly done. I stripped the power windows and locks out of an 86 C10. Installed everything and it all works with one exception. The driver door lock switch will lock the doors and the passenger switch will unlock them. But neither switch does both. Also, the pink wire is power supply for the windows, the orange/black wire provides power to the door locks, but there is also a black wire with a clip connection. Is the black wire a ground? Any help would be awesome. Thx.
