Looking for wiring schematic for fuel system. I have look online and have a haynes manual but cannot find the wire colors for my harness. Our plug that connects to the fuel pump is a three wire with black, grey and black/pink, we have voltage going to the relays and to the injectors but low voltage going to the fuel pump, trying to track down the wires but the colors we have are not shown on any diagram we have been able to find. Any help would greatly be appreicated. Thank you.
