Hey guys, sorry this might sound stupid, but i was just wondering what color the wire is for the 02 sensor on a PR3 computer, I want to install my A/F ratio gauge, and i can't follow the wire from my 02 sensor to my ecu sicne the wire is all covered up, so i'm going to connect it to the ecu.
TIA, sorry for this, i did a search but coudlnt' fin dit.

 

all i can say is check wire C16 which is ur primary wire for the o2 sensor

if u still confused let me know

it should be on the last plug on the ecu

 

hey krazie, i have it pulled out, how do i know which one is c16?

the plug portion is sticking up..

 

it should be the last one on the bottom one as it is the even wire number

and it should be white color as it is on the actual wire to the o2 sensor

 

yeah thanks i got it, it works now, seems that i'm running really lean, it sometimes doesn't even register on the gauage. ah well.
