YJ & Grand Cherokee ECU

I doubt it. Probably two completely different things. When I was looking around for one for my XJ, the one on the same year ZJ even looked different. No telling how different the programs are.
 
I saw your post over on JF, and tried to do some research for you to no avail. I checked my FSM for part numbers, but wasn't able to find it even listed. I also checked chyrslerpartsdirect.com, and couldn't find it on there. Sorry.
 
Thanks. I appreciate the help. I was going to start looking at the dealer and see if the part numbers were the same but looks like you already covered that.
