Thanks Ken and Joel for the response.
There seem to be more than two grounds in my engine compartment though.
There is a ground wire near the electrical junction boxes on the driver's
side, is this the only other one I need to be concerned about?
Also, I've read something about needing to ground the AFM after installin
the capacitor in the wiring harness. Is this necessary? Where should the
connections be made?

Still hoping for FI system that works WITH the O2 sensor connected...
