O2 sensor gage

I came across one of those gages that measures air/fuel mixture the other day, got it for free. It uses led's to output the mixture. Was thinking of putting it in my Jeep, not sure how to install it, where does the wire tap into the o2 sensor?

Re: O2 sensor gage

Splice into the wire to the O2 sensor and I think you also have to have the gauge grounded. Somewhere in the off-road.com tech articles it talks about the voltages coming from the O2 sensor. The gauge is nothing more than a volt meter. I transplanted an '85 motor with the sensor into my '79 and I have the wire coiled under the dash and will get a gauge soon.

Re: O2 sensor gage

Where should I splice in, this won't affect anything else. Does the O2 sensor go to the computer?
