I Like The Over Use Of The Shift Key Which Is A Feature Of The Forum To Make You Stop Posting ALL CAPS...

 

Oh, you do, do you! So you like all the idiot children who can't take a moment to hit the caps key EVER. Well poooo on you and your ilk.

 

NO, I was being sarcastic...lol

 

It's a piece of cake. Download the series four fsm wiring diagrams and look. You'll see where each of the wires come from and go to from the box. I'm not near my book right now so I can't tell you.

Looking at the knock box's connector, from the wire side of the plug, there is a BLACK wire that goes into the upper right, top socket. IT is a ground wire.

The wire just to the left of the one above is Gray and is a shielded wire from the knock sensor itself.

Just below that Grey wire is a Black/White wire. It is a source of 12vdc. Find a good source of 12vdc nearby. Maybe tap into pin 3I???????

Just to the left of that Black/White wire is a Light Green wire. It goes to pin 1R on the ECU.

The other sockets are empty. Right? Right.

 

Thanks for the info hailers,sorry to **** you off guys

 

Throw that **** away.
It gets ignored over 4kRPM, and it will NOT save your engine if you hit severe detonation.
