Default Oxygen sensor?'s

I just finished putting the motor/trans back in the car and have the entire harness plugged back in except for the oxygen sensor at the exhaust manifold collector. Where does this sensor plug in? For some reason I cant find the other side of the harness that it plugs into. My harness is modified as I've got v8 heads w/o TGV's etc. And I've done this many times before, but for some stupid reason I cant find the other other side of the harness for the sensor!
It's probably right under my nose, somebody please stop me from pulling all my hair out and tell me where this thing is!

hard to describe, but on the passenger side of the car near the back. if you've ever pulled your daytime running lamps connector, it's near that!!

It's where timmah said...more specifically under the black plastic cover on the passenger side of the engine bay.

I figured it should be there, but I still cant find it. I'm not referring to the sensor in the up-pipe, but the lower sensor in the collector. The problem is that nothing is stock, and the harness is upside down because my manifold is flipped. Half of the plugs are gone, which should make it easier
Anyhow, thanks for the replies, I'm gonna go put my reading glasses on and look for it. The connector is grey I imagine?

Yeah, I'm pretty sure the EGT in the uppipe and the O2 in the manifold both plug into the same general area.
