i have a 99' ex and this weekend i was planing on swapping it to a five speed but i was looking at the 5sp ecu i bought (P2P) and comparing it to the one in my car (also a P2P) and i noticed that there is one more plug for the one thats in my car now. the question is, is that extra plug the one that has the wires for park,neutral, reverse and so on?
just don't want to get half way done and realize i got the wrong ECU. :unsure:
