Help on wiring up air/fuel ratio guage

Just got the guages and I am wondering which of the 4 wires on the O2 sensor I should use for the air/fuel guage. Does anybody know?

Is the sensor wires same colors on the 2.2l and the v6 3.0?

There are 4 wires. I think 2 are grounds, 1 signal, and 1 heater. The colors are 2 blacks, 1 white and 1 blue. It should be white or blue I think, but I'm not sure.

ill reiterate my prevous statement, there is one black wire and it is the only wire which will give you a signal. When i did this about 2 weeks ago i originally tapped the incorrect wire, however the way i tapped it was using a t splice so theres no harm done. good luck

lol, everyone all tape on different wires. so which one did you tape it onto anyway?

Did we ever figure this out?

I am still having trouble on my A/F gauge. I tried both blue and white.

I think tapping the black on is incorrect

I ended up hooking it up to my yellow/red wire on the other side of the plug where O2 sensor wires plug in. All my gauge shows is stoich when I am letting go of the gas pedal, and rich when I gas it up. If thats what it supposed to show, let me know.

Which gauge do you have? If its the autometer gauge, its supposed to dance around(because your A/F mixture is continually changing). Under hard acceloration, your o2 sensors can not deliver the data quick enough so your car relys on the ECU's fuel map, and then the gauge should stay much more constant

I have a cheap autometer guage, is it working proparly considering what I described it does?
