Hey everyone,
I know the GM PID for Actual gear, but I can't seem to find a PID that would indicate if the vehicle was in Park, Neutral, or Reverse. I imagine Park and Neutral would have some kind of signal since it would trigger the neutral safety switch function.

I know I could just wire in an LED, at least for Reverse, but I am hoping to get everything (or as much as I can) displayed on the Tablet I am using for a dashboard.

I've tried to dig up a complete PID list with description for GM ECU's, specifically LS-type truck and car ECU's/PCM's, but no luck as of yet.
