I do not see why it would not, its a 4.0 it just happened to come out of a cherokee
 
There are significant external differences between the 00 and later engines 99 and later for the WJ and the earlier 4.0, Water pumps, accessory mounting, engine mounts are a few of the differences. Are you planning on fuel injection?

he said in his build thread that he is worried about the fuel injection wiring differences
 
I believe it will all work fine. It is wiring which is not my strength that I worry about.

Can you read wiring schematics? The obd1 isnt that bad to do. I haven't looked into the OBD2 wiring.
 
Never tried to read wiring schematics. 2004 should be obd II. I can figure it out just have to take my time.

sweet, worst case you can do an aftermarket refi computer and harness on it
 
Got the harness and computer, however, I am not sure the computer will work since it is for an auto.
