Air Fuel Guage

So I have this air/fuel guage that I would like to hook up. Where do I hook this up under the hood? If anyone near flint would like to give me a hand, It would be appreciated.

 

Thanks in advance

My guess is this, there will be three wires:

Black is ground

white or red is +12

and possibly a green wire that will splice into the wire coming out of the 02 sensor in the manifold.

There could also possibly be a 4th wire if the gage has a back light.

 

This is just my guess, I've seen an A/F gage onces about 4 years ago. See if you can find the manufacturs web site.

I had one in one of my many vehicles....mine was a backlit APC digital a/f gauge. 4 wire....don't remember the last color

 

Black = -

Red = +

Green = O2 sensor

? = headlights
