i figured out what my problem with my knock sensor was, the pin was kind of messed up. so i need to pin it again. i got the messed up pin out but now i need to get another pin out of my old harness. how can i do this, it doesn't seem to want to come out.

 

out of the engine bay harness mine just pulled out.

out of the ECU harness you need to pull back slightly th eside tabs on the connector, then flip up the top flap to reveal and release the pin.

good luck!
