If you look down on the blue connector thats listed..it has Low bank 1-1, 1-2, 2-1, 2-2. Then it has the same for the High Bank...which would be the best one to tap into? i dont wanna run it right to the 02..wanna hit the pcm....thanks.

While I don't understand the outputs of your PCM. The easiest thing to do would be to get under your car, find the 1V O2 sensor that is hopefully before your catalytics, and tap into it directly.

You could even trace the wire up the engine bay a bit till you find it's connector on it's harness. Then tap into it further up the loom. That way you don't have to worry about the elements as much being directly under the car.

what wire is the proper one to tap into off the 02

Usually it's a single wire. A narrow band 1V sensor has only a single signal wire.

Is this for a wideband? If so it depends on the wideband kit because it has a controller that calibrates the wideband. If you are running this off the stock narrow band sensors then the guage will be nothing for looks. I found this out the hard way when I tuned my trex cam with my narrow band. Once I got a wideband my A/F ratio was WAY off.

Thunder racing sells one with a guage and so does dynojet.

If your front O2s are on sims, your car should be running like ****. O2 sims are made for the rear O2 sensors only. The computer needs the front O2s connected so it can adjust the AFR.

Also if you have heated O2s like I do and have 4 or so wires inside the wire loom, it would be easier to just get the Air/Fuel Pigtail Tap from lmperformance. It hooks up to the harness between the harness and O2. There is a wire that is split from the harness that you connect the AF gauge to. http://www.lmperformance.com/2602/1.html This pigtail tap eliminates any questions you may have like "Is this the right wire?".

I just ran a wire to the rear 02's. Tapped into the purple wire with a white stripe. That's the easiest way to hook it up. It's a pain to get a wire to the computer and then have room to work. It's not going to hurt to hook it up close to the 02. The guage is basically just going to be for looks unless your running the AEM Wideband. But anyways if you go this route. Just pop the plastic piece up on top of your dash pull the radio, A/C controls, and console out. Then remove the shifter boot. Then just run a wire from the guage under the plastic piece behind the radio under the console the through the floor next the the shifter. The harness is right under the hole in the floorboard.
