what wiring harness & subharness do i need for a usdm ITR into an EF, if im gonna use the stock ITR ecu? thanks for the help

 

no matter what motor you put in any honda you need the stock engine harness that goes with the car. now if your bucket is a dx you gota rewire the stock harness to mpfi. search it. if its si your good to go just wire vtec. then you need a obd0 to obd1 jumper should come with instructions or search it.
