Your existing computer and harness will not work with the MPI 2.5. You will need the entire engine wiring harness, computer and probably even the dash harness, You may want to search some different forum classifieds for the correct harness From an MPI 2.5 XJ and get it all so you can easilly swap everything over. I'm not sure if the MPI was ever used in the later MJ's otherwise that would work too. Good luck.. you may want to repost this in the tech section as well to get a better response.

The AX-15 wasn't offered behind 4bangers. It's an AX-5. baby brother to the AX-15. :thumbsup:

The AX-4 and AX-5 were found behind 2.5L engines (and also the 2.8L and 2.1Ls). The AX-15 is found behind 4.0L engines (89.5 - 99). The 2 engines do not share bolt patterns.
There are 2 ways to mate an AX-15 to a 2.5L, the first is a complicated process using a bellhousing from a 4banger Dakota (which had AX-15s behind their 4bangers) and the other is with an aftermarket bellhousing.
