I need to know if when I swap my B18A into my HF CRX, if I need to buy a wiring conversion kit, or if since both of the motors (lLS motor and HF motor) are OBD0 and MPFI, if the hf harness will plug into the LS ecu and the motor itself, or if I should just buy an ls harness. I really have no clue on this and any input will more than likely be usefull. Thanks a bunch.
