Thats the stuff you need to rewire to make the car work. You can do those things with the engine in the car and pretty much put it last on the todo list.

However youll notice that the jdm harness enters through the firewall on the opposite side as it should on your usdm car. To fix this you dont have to extend the whole harness. You can do one of 2 things: 1. cut a new hole in the bottom center of your firewall so that the wiring will reach directly to the ecu, or 2: unwrap the entire harness and "flip" the part of the harness so that it reaches to your existing hole. After you flip it, youll only have to extend a few wires to things like the igniter.

If youre good with wiring, then pick option 2 and you'll end up with a cleaner install, but if you want a quick and simple way, then just cut a new hole.

Hi, about the 2 option with unwraping the harness.
Are you sure it will be long enough after unwraping it ?

it wont be.

youll have to extend maybe 30 wires.
my swap thread has good info on the wiring.
