This is a 88-91 si a6. Too many people have had their hands under this hood. I have accountability for everything but the o2 sensor wire. I cannot find it. I do have a black wire coming out of the harness underneath the distributor, but it is a shielded wire with another wire inside of it. Is this the wire thats supposed to be going to the o2?
The stock O2 sensor wire is white and pins to ECU C16.

Thanks for the info. I know the pin out. Just need to know where it comes out of the harness.
C157 = O2 sensor plug
