Ok guys I know the 4.0 swap thing is all to common and I feel preety confident in the swap after reading all the stuff on here about it. Only question is will the 4.0 harness and computer out of a 91 ex with auto trans work if I put a M50D in it instead. This is the wifes Bronco and she insist's on keeping a 5sp. otherwise I would just do the auto. I have a feeling that the computer is going to act funny and throw a code due to no feed back from the trans. Is this correct? By the way it's going in a 88 Bronco with a 2.9 and 5 speed.
