I'm dong a swap into a 96 hatch. I used a 99 SI wiring harness to do the swap. Everyting is wired up but I am missing the the third plug that goes into the ECU. I looked in my friend's car (it is also a 96 hatch) and he has the third plug but he has a 99 SI dash which has the third plug on it. This is the plug that comes from the dashboard an plugs into the ECU. Can anyone tell me what I need to do to fill the third plug? Do I need to get a SI dash harness or is there any other way that I can solve this problem?
