Browsing thru my engine bay and noticed this plug and nothing to plug it to. Can you tell me what it's for?
What is this plug for?

Curious here too. I put a ziptie over it when I did my engine remove & replace so I didn't look for it's home during the reinstall.
Was reminded of it being there recently as I'm replacing my exhaust manifolds and again saw it and thanked previous me for putting that ziptie on it.

In my California 05 that plugs into the upstream, front manifold O2 sensor. Maybe it's not used in all states.

I think you're confusing the connector with the yellow internals with the one in the background that connects to the O2 sensor (two white wires from that O2 plug). Front upper O2 plug snaps into the plastic wire cover along the intake manifold.
