Knock sensor wire problem. HELP!!!

So I was wireing up the rest of my 97 trans am when I noticed I was missing my knock sensor plug all together. After not being able to find the wire anywhere I went and bought one from gm. but I don't know where to wire it to. I assume it goes strait to the ecu in one of the 4 wireing harnesses but I have no clue where and no one includeing the dealer can get me any info or diagrams to where it gos even a pinout diagram would be nice. Anyone know where I need to run this wire. Any help is appreciated. Its also the original obd2 ecu. Thanks.

Pin D22 is for the knock sensor circuit.

EDIT: D22 is the pinout on OBDI PCMs, not sure if it's the same on OBDII.
