if off, and you have continuity(very low, if any, Ohm resistance) then you know it will act as a ground regardless if the pcm is switched on or not. if you have no continuity when pcm is off, then it would mean B6 is a switched ground. if its switched, i would run the sensor wires both to the pcm, if its not switched by pcm, then id say just run a new chassis ground and just check to make sure you have a good ground connection.

That was my plan, just wanted to hear some opnions on this.
As long as its not a switched ground, which it would be very doubtful being a shared ground, a ground is a ground as long as signal stays clean.
