Helped a friend change a Motor the old one locked up
should of been pretty standard ive changed several just not in a jeep but we're having all kinds of issues no power runs on like 3 cylinders loss of communication here is a list of what shows when I scan it the motor come from a salvage yard but only had 40k miles
We tried a new pcm but that didn't change anything either
Any thoughts /suggestions im lost on this one

 

Did you ever have any luck with this? I'm getting ready to do the same with my 15 Cherokee and trying to figure out what I'm getting myself into.

 

Not yet still trying to figure stuff out

 

Anyone know what wire or terminal on the plug powers the tcm so I can check for voltage there
