91 4.0/4.6L engine 93XJ engine wiring harness 87YJ recipient. Anyone have the FSM for a 93XJ engine wiring harness? maybe even a 87YJ also. Does anyone have info on the five wires that are needed to connect and start the engine? I have found the wires i need for the starter and have ran a wire from the relay to ignition so the starter will turn the engine over. I have grounded the fuel pump and ran a positive wire from fuel pump to the front of the vehicle when i give it power though i hear the pump kick on but no fuel the pump is a e2000 inline... is there a relay that allows the intake sending unit to allow fuel to flow?
