what wire do i hook up my air fuel ratio gauge to get a good reading on my 2001 silverado 5.3 with the sts set up?

 

Did your gauge come with some type of sensor and or a bung to weld into your exhaust for mounting it? Post up what you have.
Is it just an AF gauge or a wideband?

 

The only AFR guage worth fooling with is a wideband,you'll need to add a bung into your exhaust pipe to mount the wideband o2 sensor near your front narrowband o2 sensor.I prefer mounting the guage on a pillar mounted pod.Or you can unscrew a stock o2 sensor if you don't plan on perminently mount the wideband o2.

 

its juat a a/f gauge not wideband and its electrical just 3 wires power ground and another wire that am tryin to fine out where it goes?

 

To be honest, I would not waste your time with that non-wideband model. It taps off your existing narrow band O2's and will not read accurately outside of the 14-15 range. Save a few bucks and buy a wideband, your engine will thank you for it!

 

How are you tunning this??

I also agree with ktmrider, buy a wide band.

 

true am saving up for a wideband now just my friend gave me this one and i have the pod with an empthy spot so i just wanted to mount it on and hook it up. does n e one know what wire i need to tap into and where so i can get the light show?
