We have a 1988 Ford Ranger extended cab center tank. We bought a new connector for the fuel tank but from the color of wires from the truck to the new harness that plugs into the fuel pump are different colors. Can you give us the color codes to match them up. We know black goes to black and the yellow with the white stripe goes with the yellow with the white stripe. Can you tell us which one is the positive that goes to the truck? Basically what we are looking for is: we want to know how the colors go from the truck to the harness. If you need more information i will give you my phone number. Where can i get a schematic manual for the wiring.
