[V8] signal wire to ground OXS

[dsaad at icehouse.net]

If you just leave the wire open, the ECU will recognize this and revert to open
loop mode but the car should be perfectly driveable. You will lose some power
and MPG may go down because the mixture will tend toward rich, but other than
that the motor should run fine.

Actually I would expect this same behavior if the O2 wire was open, grounded or
shorted to 12v (don't do that last one). The software should recognize this as a
bad sensor and respond accordingly.

What do you hope to learn by grounding it?
