air/fuel

[drppdime96]

I need help installing a air/fuel gauge on my 96 sonoma 2.2ltr... any help would be appreciated...

well not sure what the wire colors on the guage are but i would say
red-switched positive source
black-ground
white-positive only when lights are on
green, purple or whatever is left-to o2 sensor

Which o2 sensor.. aint there like 6 or somethin on the car and do I just splice it..?

[nomaboy]

any 1 of the 2 before that cat. just spice into the signal wire from the 02 to computer. there will probably be multiple wires on the 02 so just splice one at a time till you find the one that works. on mine it was the purple wire.
