i have a 89 comanche that has the 4.0 renix fi sy on it with m/t the computer is bad in it. So i got bord and have a totaled 93 xj 4.0 a/t. I want to have the ho harness run the older non ho 4.0. I'v look on the fourms and serched the internet but cant find the answers i want. I have already pulled both harnesses out and i know that the flywheel will have to be changed along with some sencors. Is the ecu from a ho differnt from m/t to the a/t is the harness differnt besides for the trany computer part of the harness , dose the flywheel and flexplate have more or less teeth for cps can you do this with lots of time.
