has anything on the engine like Inj dizzy and sensors been swapped out to obd1 stuff. if not scoop up a harness for a 96-98 gsr or ls integra and drop it on the motor. also depends on how many plugs is on your dizzy. If it has one its obd2 so use the above stated. If it has 2 then you got to have a obd1 harness.and change the injectors to obd1
