Dunno exactly where it goes back to in the harness, but it might be worth investigating to see. I don't believe the Oil Pressure unit affects spark, but i could be wrong. If its a 95 it should have a box in the engine bay, or is that what you meant by no code reader? Link to comment Share on other sites More sharing options...
