I have a 2000 jeep XJ with the 4.0L, 4WD, and am in the need for the complete wiring harness that connects to the main connector. It has the Black and White ECU connectors and of course the fuel injector connectors etc. looking through my parts manual, I cannot find a part number. Can anybody tell me what years also the same harness works on? And or the part number? Someone sent me a 98 harness it it won’t work

I believe the 2000-2001 are the same, maybe also the 99. You can't buy new ones, so the only option is used or rebuilding what you have. I have a number of wires with cracked insulation and I am planning to rebuild mine.

2000-01 are the coil over plug years whereas the 99 and older are distributor years. So he's gonna be sticking to the 00-01 specifically


I'm unaware of any complete kits out there. Really your best and most affordable effective bet will be a you wrench yard. They don't charge an arm/leg for the whole harness and you also get the benefit of inspecting and removing it with your level of attention/care vs the gamble on someone else' patience. Done this many times.

Might not even be '01 if the '00 is a Federal Emissions one.
'00 could come either way.
Best of my knowledge all '01's are CA Emissions.

All I know is that Jeep for the year 2000 and 2001 modified the set up. These are the only two years however, it’s best that I stick with a 2000 just in case. I may not have any choice except to do it myself. I just wished I had a way of figuring out what Pin inserts I need
