There is a white wire coming off the 02 sensor...its there.

The light is lit up all the way RICH, not stoich, correct. Green, all the way to the right. That means the power and ground are OK, but the connection to the 02 sensor is not there.

Look again and tap the purple wire coming from the guage (most probably that red extension wire) to the white wire from the 02 sensor...there are 4 of them I believe, one is white.
