85 CJ Temp, Oil and Fuel Sender Wires
I am trying to get my transplanted 94 YJ 4.0 motor operational in my 85 CJ. I have put in new 4.2 temp and oil senders into the 4.0 engine so I can use my existing CJ dash gauges. I swapped this motor in about seven years ago and in the meantime I have forgotten or my labeling has faded on the CJ engine harness what goes where. I have a Jeep FSM for my scrambler, but it is REAL weak for back tracking the wiring harness and connections. I am wondering if there is not a supplement for the harness diagram. ITMT, can you tell me which colored wire goes the engine temp sensor? The oil sender has two male prongs on it and for the life of me, I can't find anything in my CJ harness that appears to match up. What should I be looking for? Lastly, my swap uses an E2000 external fuel pump for pushing fuel to the 4.0. I put in a new sender and tank into the Jeep. The fuel pump runs fine. I shared the ground location for the fuel pump with the sending unit ground. However, I can't get the gas gauge on the dash to move and I know I poured at least 4 gallons into the tank. What voltage or ohm readings should I get and where should I take them for trouble shooting? Thanks for the wisdom.
