i dropped in a USDM 1994 integra ls engine into my vx hatch, i was wondering do i need to use my old vx harness? i looked at the harness that is on the engine and it does not have a female plug on the passenger side where there is a male plug coming out of my car harness. right now everything is hooked up with the ls harness and the engine turns over. i also have fuel and coolant going through the engine, but it will not start. could this be related to the missing plug on the ls harness?
thanks for the help
