I have 90 dx civic hatch, bought an si hatch parts car. I have the intake,distributor,ecu and engine bay harness. The only problem is, is that on connector(six pin square) i thinks its the cyl sensor. Someone said that you just have to run the two wires to your ecu. Ok thats fine but i have six wires not two so i don`t get it. Is there anybody that has done this swap without changing the entire harness and that would be able to explain step by step how to do this? please help me.
