Can anyone tell me what wires (pin #) from the PCM ground on the back of the driver's side head? I had 1 pull out of the factory crimp (which cause everything to go haywire) and i got it sorted out for now but i'd like to make it cleaner by re-grounding it closer to the pcm.

Ive read the pinouts for our pcm but i havent found the wiring diagram of where they all actually run too.
