I think that's an incredibly good idea!

I saved Larry's post with the part 4-wire part # for future reference. (-:

A 4-wire O2 sensor, with the ground connected to the same location
as the ECU ground would eliminate O2 problems caused by
slight (or sometimes not so slight as I found out) voltage differences
between engine and chassis.

A 4-wire sensor sounds like just the thing for digifant vanagon
owners. I would certainly do it to mine if I didn't have other
plans already... (-:
