I have a Narrowband Autometer Cobalt Air/Fuel Ratio gauge, and need to know where to hook up to the wire for the O2 sensor, i've heard about tapping into the ECU, but have a bit of trepidation in doing that if i can just tap into one of the O2 sensors...

any help would be appreciated, i'd like the gauge hooked up by christmas...

 

bump?

 

i can't remember which wire is the signal wire but a narrow band a/f gauge will serve you no real good. you're better off to buy a wide band and have a separate o2 sensor for that.

 

i posted a thread on which wire i used. should be searchable, ill find it

I still love that no one posted on it.

 

thanks!
