Hey guys I'm new here. I have a 1990 4 cyl car and want to swap a 5.0 into it. I just have a couple of questions. I want to stay fuel injected. Do I need to get a 5.0 computer to swap into the car and do I have to change any of the wiring harness. Or does everything just hook right up? I know about the rearend, trans, etc. I just need to know about the 4 cyl computer. I would appreciate any help on this subject. Thanks.
