i have a 2000 crv and am trying to attach my air/fuel gauge. which o2 sensor does it go on? and where are the harnesses located?

thanks!!

 

No offense, but why would you want to put a toy of a meter in your car? Unless it's a wideband, it's pretty much useless and is just another reason to lure thieves to your ride. Anyhow...I've always connected it to the o2 nearest the cat to the white wire I believe it was.

 

I'll second that. The ones that attach to your o2 sensor wire are just a light show and are very inaccurate.
