I have the engine already it came from a 88 Formula and i have the ECM from the formula for the engine. Would it be wise to get a new wiring harness because i have the TPI's ECM or what should i do?? Also what else do I need to Swap the engines?? I am doing the swapping this summer.

 

i'd try to use the harness, ecm, and prom that went with the donner engine.

I know a guy who redid the TBI harness for TPI. Although he's proud of the accomplishment, deep down I'm sure he wishes he would have just gotten the TPI harness. It was neither time nor cost effective.
