Wiring an Air/Fuel Raio gauge
I have an Autometer air/fuel ratio gauge. I was under the impression this wired directly to the O2 sensor. However the O2 sensor is a 1-wire and the gauge is a 3 wire (1 being ground).
Do I need to get a different O2 sensor? Or splice it in somehow?
Thanks!

How much was the gauge? If I cheap out I'm going to do this instead of getting a gauge.

If its not heated the readings would be off untill, pretty much, the closed loop when the O2 sensor is warmed up.
