Hello, i was fixing up S5 NA today. I was checking to see if the o2 sensor is hooked up since it has engine light on. And its plugged. Then i check my S4 NA for some compare since it passed smog and i was really surprised on what i see.

o2 sensor on my s4 na, was never plugged. The wire seem cut off. And im trying to find the wire that connects to it. I cant find diagram for it. Or anyone can help me out?

It breaks out of the wiring harness. Check behind the throttle body it should be around there.

Is it in the same location as the s5? i can't find where it the other side plugs into at all!! I've been searching and no one seems to have pics for the s5 lol

It comes out of the harness near where the wire that goes to the BAC comes from.

Here is what the connector looks like (on an S5).


It's a white sheilded wire that come from the harness right here. Comes out of the main wiring harness next to the BAC connection.


Note: I have mine wire tied up like it is in the picture because I'm running a wideband O2 that's hooked up at the ecu.

It should be a white plug in the back over the Transmission close to the left side lookin from the front. If inside the car its US pass. side On the N/A S4.
