I went by the skillsilla wiring guide to start my rb20 up using my KA lower harness. I was told that I have to wire in the knock sensor harness from the rb20 lower harness and tap it into the ECU. I did not do this, but the car still runs.
Is it neccessary to do this? what does the knock sensor plug look like?
