hey guys, this topic has probably been asked before but i couldnt find it in archives. well, i need to know which wire on my ecu is the o2 sensor. i have a 96 gsr and im installing a a/f guage. also could you tell me whats the best place to tap into power? thanks guys

 

any constant power signal... i think its white wire for the signal...

 

so i should wire the purple wire from the gauge to the white wire on the ecu? there are so many wires it makes me bonkers. pictures would help. ive been on autometers website and it just tells me to connect to o2 sensor. i just want a picture of which wire that is.

 

yeah solid white

 

i've searched so many places trying to figure out which wire was my o2 sensor, thanks for the info.
