ok so i been really really confused with the wiring part of swapping the engine, ok so am i supposed to wire my factory harness to adapt to the jdm ecu or the jdm harness to adapt to the factory ecu? also when making them adapt do i just need to make them adapt to be able to just plug in or is there more? can someone help me out with this.

This would be better in the wiring or the FI forum... BUT

Ideally neither. You would usually want to swap the JDM motor, ecu, and harness into the USDM car. You would modify the JDM harness to fit in the USDM car (check out Tweak, he's god with these).

I would also highly suggest you read these threads.


Between those two threads, you should have all the wiring questions answered. :)
