Should i use the jdm P72 ecu and harness that come with the complete swap, or do what i planned and find a usdm harness to mate up with the jdm ecu, or just use both usdm harness and ecu? Im just kind of stumped on which one is going to be easiest, because i heard jdm harnesses arent worth shit, because they are backwards, but i figure if its mating up with its jdm counterpart, then it should be fine, correct? What would be the easiest way of doing this?

 

Use what you are given

 

Alrighty thanks. All i needed to know.
