I had to change the wireing harness on my 88 Bronco II My tranny has a three prong plug on the tranny and I think it is for the 3-4 shift and the TC lock up The wireing harness I found only has a two prong female plug end. I was sure the one I took out had the two prong also and it shifted fine before but there is now way it was hooked up. I am bumb founded about that but what is more important I have no 3rd or 4th gear now. It shifts from 1 to 2 okay. It acts like a modulator valve maybe but like I say it was working fine before I changed the harness. Somebody help me, please
