A/F Gauge

I recently bought an air/fuel gauge from iEquus and I tried finding an install thread but to no avail. I was wondering if anyone knew which wire I needed to tap to get a signal, or if it would be easier to tap each O2 sensor separately. If that's the case, where does the other O2 sensor connect? I'm getting wideband sensors soon but I just want to see how I would go about this. The instructions that came with the gauge were for a 4 wire O2 sensor btw.

If I remember correctly you need the wideband unit..not just the sensor for you to get any kind of correct reading

How are you planning on providing them a signal input in order to control A/F?

Apexi NEO is what I'm looking at. I just want a gauge to monitor more easily rather than changing screens or whatever on the NEO.

As far as I've read on Apexi's site it can act as a wideband controller

It's far more complicated than that.

ok you can use the neo to adjust your a/f ratio. but the neo will not tell you what your current a/f ratio is. that is why you need a wideband. The wideband gets the reading and then displays it via a guage or screen. Some can datalog so that you can record what is going on while you are driving so that you can go back later and adjust the settings with your neo.
