where is the primary O2 sensor wire on the ECU for 99integra gsr? ive been looking all over for it and can't seem to find it. i also tried the white wire on the C31P connector ( page 11-38 of helms), but it was for a 00ITR ECU. that was the closest thing to my car i can find on the web.

 

please?

 

That is viewed as if you were looking at the ECU.

 

thanks man, that helps a lot... the helms actually didnt have a pic of the 3rd connector. it only had the 31P connector which is the blue one in the middle. thanks again.

 

is that what u tap into for the A/F gauge?
