Extra wire HELP! Rear of engine

[gaber6]

I know I disconnected both, but only one has a place to live. The one between my fingers is the O2 sensor for the passenger side. Not sure what clips into the one shown. I hope to start the car tonight. It's been 3 weeks for my head gasket job.
Is there a spot on the back of the engine it plugs into that I can't see or feel?

Never mind. I'm a moron.

What was the end result?

Just curious

The wire comes from the main wire bundle on the passenger firewall area. I tucked it up there when I unclipped it to keep it out of the way. It blended in perfectly. After looking for it for 30 minutes I walked away and came back and it was right there.
