Anyone out there can enlighten me on how to wire the air/fuel gauge?? I have the Greddy warning meter. It comes with a "replacement" HO2 sensor. If I am replacing the factory HO2 sensor directly, how does the gauge read the output? Some enlightenment would be greatly appreciated. I need this gauge working to try and tune my car a little better.

Hey Larry,
I believe the O2 sensor come with the gauge isn't replacement of the original one that is there.
You need to drill it into the good placement in the header, possibly close to the primary O2.

 

Damn... I think I'll just have Evolution install it. Thanks Randy.

 

I would suggest that.
