a/f guage hookup

Does anyone know which wire I tap into my ecu to hook up my air/fuel ratio gauge my car is obd2..or a website that shows diagrom?Hasport has it but nothing worked when I tapped into it.Any suggestions???

go ot www.automoter.com and look at the pdf file they have on the site. just look and you'll find the instructions o how to hook up a a/f gauge

yeah I got the gauge hooked up just not to my o2 sensor and autometer isnt goin to give me a diagram of my civic ecu I need to know a site that will have that diagrom so I know which wire to tap into.

I just went by trial and error. I have a 4 wire O2 sensor, two of the leads are black. Leave those alone. Just try each of the others to get a signal. Not the best way but it works.
