Just switch out all your sensors for usdm ones, plug in your old b14 harness and that should get you going. One thing is though that if you use the det injectors which should be 370s with your stock ecu its going to run very rich. You will need a way to limit the fuel getting sprayed throuh em. Like a jwt ecu or safc. I ran my swap with the det injectors and it kept flooding my engine. Hopefully that helps some. Shoot me a text or call 440-360-0573. I dont know everything but enough to get you going!
