I have an complete assembled 04 long block that i am putting into a wrx. I already got intake manifold and throttle body as well as the cam position sensor needed for the wrx. I was trying to wire it up and did not even take into consideration the engine harness might be different. Does anyone know to do the entire swap if a 02 wrx engine harness is also needed?? thoughts or links please
