A/F gauge Install.... HELP
I have everything in place to install a digital air fuel ratio gaue in my new A-pillar. Kinda for looks as it won;t come close to doing what AutoTap does. Here is the BIG question. It only has 3 wires. 1 black for the ground. 1 red for the switched 12 volt pwr and 1 orange for the connectin to the O2 sensor signal wire. I see 4 O2 sensors. 2 inthe front and 2 behind the cat's. I have TPIS LT headers and corsa indy exhaust. Shouldn't matter. I have the PCM pinouts bbut I cannnot determine which one to tap into or do I just choose any of the two front sensors to tap into (as long as it's the signal wire) OR do I tap into BOTH the two front sensors signal wires?What the hell? Need some help please. The instructions are vague. It's a Cyberdyne electric bar graph A/F Gauge. Any assistance would be welcome.

You will have to choose one of the front sensors. Some say the drivers side bank tends to be a bit leaner, but it shoud not matter much with that type of guage.
What the heck! where did that sig pic come from. This is pretty funny.
hmm, it's back to normal now.

Re: A/F gauge Install.... HELP (QuickSilver2002)
Thanks man. Is choosing a leaner running sensor better than a richer one better for adjusting to a stoich environment overall or would this be bad decision. I had Ed's programming and my signature is pretty much up to date as fas as mods. I still seem to get some "pinging" at low rpm now after two readjustments with Ed. He is great at what he does but they haven;t been Dyno tunes. I wm working on getting a dyno tune. I also have LS1 Edit. I am working on picking up a spare PCM as Ed locks his work plus he does an outstanding job anyway and it would be nice to have a spare PCM. I am digressing here. So, bottom line, DO I come off the signal wire immediately after the harness that connects the sensor to the PCM or do I tap into the wire coming out of the PCM. If it's the PCM which pinout do I choose:
HO2S Low Signal [Bank 2 Sensor 2]
HO2S Low Signal [Bank 2 Sensor 1]
HO2S Low Signal [Bank 1 Sensor X]
HO2S Low Signal [Bank 1 Sensor 1]
HO2S High Signal [Bank 2 Sensor 2]
HO2S High Signal [Bank 2 Sensor 1]
HO2S High Signal [Bank 1 Sensor X]
HO2S High Signal [Bank 1 Sensor 1]
This SH*! is very confusing for the first timer. I have done everything else on this car or just about. Am I overthinking this stuff? BTW- Thanks for your reply Quicksilver.
