Hiya guys

I have a digital short band afr gauge that reads from 7-20 so although short band still gives me an idea of what afr is, before anyone says theyre waste of time ie the crapy stoich lean gauges which are usless on turbo cars.

Anyhows the question im asking is which wire off the lambda sensor goes to the guage ther is a choice of 3, 2 white ones and a black im assuming its the black but want to confirm before i start cutting into wires.

Thanks.
