what are you talking about ? you have a j35a? and you are putting it in a car , what car? and you need to use a auto ecu like the one that came from the motor. then you call or pm me to make you a wiring harness to go in the car or be brave and do the harness your self. but the wiring in the car does not need to be changed out to do the swap.
