can you check for continuity between the normal pcm to chassis ground and the B6 pin?
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.
