I am getting a 34 knock code and 54 auto to ecu and is a s13 auto to manual car. I have a wiring specialties harness but not the knock harness. I had to dewire from factory harness and and re pin to wiring specialties harness connector. I know front and back was right pin and assumed other 2 in connector were each ground as it was in factory harness. Seems twice as long as it should be tho but wanted to just depin connector and slide pins in new with no cutting. If I clear codes start it 1min turn off check codes 34 knock code is there already.
