02, signal wire

[00 Red SS]

Im doing wiring and ready to wire up my a/f gauge. Which wire is the signal wire from the 02 sensor i didnt look really close at them but theres 2 whire wires and a black im assuming the black is the ground so that leaves the power heater wire and the signal.

It's the black wire. I'd search the threads for the wiring diagram and just pull off of the puter connector. It's a lot cleaner install.

ranchero5.0- is correct - its the black wire. I just ran a wire from the gauge through the shifter hole in my car and tapped into the sensor itself.
