Ok so here is what I have an issue with. I have a JDM H22A. The factory harness on the motor is uncut and came with the JDM ecu. I also have a full uncut Y8 harness and P28 with chrome and H22 base map. Is it possible to just keep the factory wire harness on the H22 with JDM ecu or do i have to use the Y8 harness. If I have to use the Y8 harness the end of the Y8 harness only has one plug that goes into the driverside harness that goes into the dash how do I wire that so it will work on my stock DX harness that goes into the car?
