I have no idea about fitment into the Mitsu, but it's not that difficult to make the AW4 work with a factory Jeep TCU and part of the wiring harness. I did this to my Eagle I recently sold and it worked like it was installed from the factory. It just needs power, ground, input from the brake to release the torque converter and a TPS input. I added a Jeep TPS to my carb linkage. Also, there is a TV(throttle valve) cable that needs to connected to the throttle linkage and the appropriate shifter needs to be installed.
