Hey all,
Doing some research..
Looking to possibly put a 4.0 L engine from an LJ into my CJ.

The engine I'm looking at does not have PCM (?). What options do I have? I'd like to purchase a stand alone wiring harness rather than messing with trying to pare down an existing harness...(not sure I can even get it.)

thoughts?

You can get the engine harness from ebay and an ecu.
 
I have the pcm from my 04 auto LJ, but I'm not sure if it's even good. I'm LS swapped and we tried to keep the PCM to run jeep gauges but spent way too much time trouble shooting then ditched it for aftermarket gauges. I'm not sure if we cut something we shouldn't have or fried the pcm.
