wiring Air/Fuel Gauge question

[VXtreme]

Need a question answered. Just bought a Auto Meter Carbon Fiber Air/Fuel ration gauge. I need to know if anyone knows where and how to splice the gauge wiring into wiring harness utilizing the stock o2 sensors.

My mechanic who did mine is not around to ask now... but doing some searching I found this from HotSauce:

Heres what the 4 wires are:

2 are for the preheater.

1 is ground.

1 is signal, and will give a reading of about .95V.

I have no idea what the colors are, but with a DVM it should be easy to figure out.

That being said, I see no reason to have an O2 meter unless you are going to tune with it, and then I'd want a wideband O2 sensor.
