$750 LT1

I have a 1995 LT1 camaro, and need help installing an A/F ratio gauge.

There are 3 wires coming out of the gauge. One is a ground (black). the other Power (red). I can do those. But there is a violet wire that goes to the o2 sensor signal. Now where do I get the signal from? Somewhere on the PCM? Any help would be greatly appreciated.


Thanks,
Daniel

Either the left O2 sensor (purple/white wire from pin C20 on the PCM) or the right O2 sensor (purple wire from pin C8). Splice into the wire somewhere between the PCM and the harness plug. Do NOT splice into the actual O2 sensor wires.

If you want to be able to select either sensor, wire the two sensors to the outer terminals of a single-pole/double-throw switch, and put the purple wire from the gauge on the center terminal.

Moving to "General F-Body Tech...."
