Chevrolet Repair: 97 S10 wiring schematic fuel circuit, wire colors, fuel gauge

Question
were can i find a  diagram of wire colors?  
Which two wires and harness go to the fuel gauge?


Answer
Gray and black operate the PUMP.
Black is ground. Gray runs pump.
So the other wire, or two wires, are for the sender in the tank.

Also, at the public library, in the refference section, you can look at all types of shop, Mitchell, Chilton, Haynes and other manuals for that year and model of truck.
