Re: 16168625 pcm
No, the DRAC isn't a part of the PCM, it's just mounted there in a S10.
After thinking about the knock sensors some more, I realized, I never completely figured out what the difference was between the one knock sensor system and the two knock sensor system. The difference may not be in the PCM, but may be in the wiring harness used. I would try it first with just one of the 4.3L knock sensors. If it doesn't work, then I would add the necessary wiring and second sensor.
The right side 4.3L knock sensor won't fit in the block drain hole, on a V8, so I used one of the mechanical fuel pump bolt holes.
