My dad has a 1987 Chevy Silverado 1500 that is his version of a perfect truck. About a year ago I tried to get it running, both the fuel pumps were shot in it. I hastily cut the wires running off the frame rail that tees off into both of the fuel pumping wiring and the fuel selector valve wiring. I need some help with figuring out what to wire where. I have a tan/white, pink, gray, and tan wires running off the frame rail. Each tank has purple, gray, and black wires. The selector valve has a pink, tan, green, pink/black, and pink/white. Any help would be appreciated!
