I finally got the engine into the car today. I have to pull the tranny again, but that is a different story. My question is I have one plug on the wiring harness too many. Where does it go? It is a 4 wire grey plug that is on the strand that goes to the alternator. The lead is long enough to plug into anything on the back side of the engine. There is nothing back there that takes a plug like that. Does the fast idle valve from a 93 Integra LS have any electronics?
