Who can identify where this plug goes, and where the wire attached to it comes from. I found it broken off in the rat's nest while I was putting everything back together. Here are the pix:

kinda looks like the O2 plug

 

looks like the o2 sensor plug. Go look at your downpipe where the o2 sensor is and see if it's disconnected

 

Does it plug into the o2 sensor, or does the wire end connect to the o2 sensor? When I looked at it on my downpipe, it didn't have anything connected to it, but it felt like a wire might have attached to the tip of it.

That's the male end of the O2 sensor connector. The wire should be connected to the 02 sensor which is screwed into your precat/downpipe. That connects to the female end which is usually attached to the back (firewall side) of the upper intake manifold where the lift hook is attached.

 

Thanks guys. Sure enough, it's the wire to the o2 sensor. Now I have to figure out the easiest way to get take off the sensor so I can solder the wire back on. Does anyone know what size wrench fits it?
