Welll... that's a good question.
Ideally the O2 (and all other sensors) should share a common
ground point with the ECU signal ground.
Damned if I know where the ECU signal ground is. I would
guess it's in that cluster of brown wires that all connect
at the left side of the engine bay near the left head ground strap.

I'll try and photograph and document all the ground points
I find when I rip my digifant stuff out in another week or so.
