Shouldn't you have two o2 sensors on your cat and one on your header? And the one on head should be a 4-wire?</TD></TR></TABLE>
I thought 91s were OBD1, so there'd only be one o2 sensor...on the header.

if he's running the obd2 computer he needs two o2 sensors....
without knowing what computer you're running or at least which obd you're running your post isn't giving anyone enough information to even attempt to help you.

im asumming u are still running obd0 with your one wire o2
u can splice either at the ecu harness for 02
or u can splice the 02 wire itself and hook it up to the purple on air/fuel (for autometer anyway)

I have a Faze air/fuel in my car. I wouldn't reccomend cutting the wire ( I did, if you didn't notice, there really isn't much room to fit your hand in there.) You can still get an accurate reading by running it under the car and just literally plugging it into the harness.

air/fuel gauges are worthless unless they are wideband.... a autobling, faze, autozone, whatever brand... won't give an "accurate reading" no matter where you run the wires to/from....
but that's not even what this thread is about...
nobody is installing an a/f gauge.

Read the title...and the origional question.....that's what it sounds like to me. Just a thought. Sry if offended. BTW, my guage and my laptop give out the same reading, I have no complaints.

congrats! you have TWO displays with the same worthless a/f reading! rock on dude!
-Erik <--- wonders when silly '05 Stunnas will learn that an a/f reading is worthless if it's not a wideband reading

He never even asked if he should get one or not, yet he gets another h-t regurgitation of "air/fuel gauges are useless unless wideband." Yes, so what? He already has it so quit trying to be so cool to your h-t e-buddies and help a guy out.
The standard narrowband may not be accurate, but it does give you an indication of what your ecu is "seeing" either lean or rich. This can lead one to investigate further into why the ecu sees it as such.
You forgot to tell him that he needs a jdm climate control because the jdm one is more accurate
