NEED HELP! Knock sensor wiring diagram

[dirtymazda]

I have a 99 OBS K3500 with a 454. I recently discovered that the drivers side knock sensor is broken and the wire is missing. Can anyone tell me what pin it is on the pcm or where I may be able to find it? The passenger side either has the correct wire, or the drivers side one is long enuff that it reaches over to the passenger side. The truck runs great at first but then slowly starts to lose power like the timing is off. From what I understand the knock sensor will pull timing out of the motor if the sensor is bad. Hopefully someone can either post pictures of both side knock sensor wiring or knows the correct pin in the pcm connector that I can trace it myself. Thank you in advance!!
