[QUOTE="rgirardi, post: 436773, member: 19437"] Hi I am going to swap in a 1995 4.0L into a 4.2 L 1988 YJ, I have found several engines/harnesses/ECUs but they are all out of an automatic Jeep. In the early years will the ECU from an automatic tranny work with a standard. I believe the engine Managment system was very simple so the type of tranny shouldn't matter. Just wanted to see if I am wrong. Thanks Ralph [/QUOTE]
