I have an autometer air fuel gauge it has one wire that is suppost to go to the computer i think. does anyone know what it hooks into?

 

They hook to an O2 at the least.

 

Sounds like you bought just a "gauge" not a wideband kit?

If so you wasted money.
The pcm constantly varies AFR to keep the O2s bouncing back and forth across 450mv which is 14.7:1 AFR and the ONLY point at which a narrowband is accurate.

Don't just take my word for it though search here and you will find every time this comes up the same answer is given.

The constant varying of AFR by the pcm will cause a wild lightshow on a bar type display.

 

Yeah, But the look cool. If you cant find anything out shoot me a PM. ill be back in my shop tommorow and I had one hooked up on mine at one time. I can look on the wiring harness and tell you what pin location on the PCM they go

 

The O2 signal wires are purple (pin C8) on the passenger side, and purple/white (pin C20) on the driver's side. Hooking up to one, you'll only have poor/limited info on only one bank of the engine. Hook it up to both, via a single pole, double throw switch, and you'll be able to select which bank of the engine gives you the psychedelic light show.

Really not worth it.

 

Definitely an uber waste of money and effort.

 

I have AEM wideband, i had this gauge from a long time ago. I have an open spot for it to go kinda looks weird with nothing there so i figured i might as well throw it in. thanks for the help.

 

I have mine hooked up to the wideband sensor in the headers and the gauge in where the center eyeballs were

 

^ this is why I have been a fan of the Pontiac interior...I'm a big fan of the gauges in the dash- they look as factory as you can get IMO..not the typical 'pod warts' that us Camaro guys have to do..myself included.

 

You really can't have "too much" info....... center vents + pod warts...
