autometer air/fuel gauge wiring.

THis is a ultralite gauge, which wire do you use comming off the computer wiring harnness. I have a scanmaster, can you use the wire thats tapped into at the dianostic plug?

I thought the only wires required were +/- and one to the O2 sensor? Anyone else have something different?

Thats the wire I was talking about. Rather than running it through the firewall to the o2 sensor, I was going to wire it to the computer.
