SLO_ken, thanks for the replay. I have been speaking with Thisguyyouknow on the forum as well about this. Basically what has been concluded is I can connect the green w/ black tracer from the O2 sensor and run it back to the fuel pump relay to the same pin that connects to the fuel pump power supply wire(need to get the exact pin number that connects to the relay when I get back home). The O2 sensor and fuel pump will both get continuous 12 volts in this configuration now. Whereas before, the fuel pump voltage would drop because of the ballast but the O2 sensor would always get a constant 12 volts.
Thisguyyouknow and I were discussing the red w/ dark blue tracer wire running from pin 37 on the ECM to the ballast resistor bypass relay. I was considering just cutting this wire and not using it but there was some concern with the ECM not getting a signal/ground from the relay and throwing a check engine code. He suggested splicing the pin 37 red w/ dark blue tracer wire (pin 86 on the ballast resistor bypass relay) wire from the ECM to the blue w/ white tracer wire (pin 85 from the ballast resistor bypass relay) to give the ECM the full signal just in case.
Being that the 94-95 XJs has pin 37 on the ECM empty I'm not sure if this wire is even necessary to hook up? Could I get away with just cutting the wire and leaving it disconnected, get a 94-95 ECM, or just make the splice and call it done? I would ideally just like to cut the wire and remove it all from the harness. Anyone know for sure if this will work or could I get a possible check engine code of the wire isn't connected?
