I have a buddy doing a 4.0 swap into an MJ that I picked up for him off here last year. The MJ came tore down with no motor(originally a 4cyl truck), but a complete 4.0 warness(unknown year) in a box in the cab. He has a good 4.0(unknown year) with a harness, but upon further inspection, he is not sure if the harness is the same year as he was told that it was the one that came with the motor, but differing wire cuts say otherwise.
So, two seemingly good harness, one good motor/tranny/trans, and one MJ.
What we need to know is how to determing what year the parts are, ie the motor and the wiring harnesses. Are there numbers that we should be able to locate on the block(if so, where?) and the harnesses?
They found two different numbers on the intake manifold. They are: AY11596 and 33007067.
We also have a complete 97 xj that is being used for parts and a template to put this thing back together, but the motor appears to possibly have jumped cogs on the timing chain so we are not using that motor.
Thanks in advance.
