I have an A/F gauge left over from my previous vehicle and need to know where to tap into for the o2 sensor. I know that with a narrowband it is pointless and I shouldn't waste my money and what not, but I really don't care. I tried searching and went through 33 pages with no help. Thanks in advance

 

wondering the same question as well!

 

I agree, the gauge is useless. Cool to look at though.

If you can find electrical schematics, it should be easy to find.
