O2 sensor (cant find connection)

i really tried to refrain from posting this but, i found out that my o2 sensor hasnt been plugged in for quite sometime (mabey longer than the 2 months that ive owned it) its something that was just over looked... ive searched, and broke out the fsm for help but i guess its something so simple that it doesnt need explaination. anyway i cant figure out where the hell it goes. can someone with a S4 turbo2 take a pic of where the damn thing goes please? please excuse the noobness of the request, any help is much appreciated.

I'm pretty sure there should be a one wire spade connector (female side), the actual thing will look like a faded tannish color.

I could post mine up but my harness has been moved around a little because I have an HKS turbo manifold and I need to protect it from the heat of a relocated turbo.

The oxygen sensor wire comes out from under the rear of the upper intake manifold (on most cars).

If you can't find it, look for the large grey wire in the injector harness (going to passengers side under wiper motor). This is the oxygen sensor wire (shielded). You will have to design your own connection method (spade connectors, etc.)
