Couple Electrical Connections in Engine

[Batterystang]

The first is an "O" type connector which could fit around a head bolt. It's apart of the connections that go to the Throttle Body. Is this a ground?

Also there is a pretty thick gauge "12-14" wire coming from right near the coil on the drivers side all the way to the passenger side. It barely stretch's to the stud on the alternator. I'm pretty sure it goes on along with the little red wire on that stud, is this correct?

Thank you!

The first wire under the TB is probably the O2 sensor ground.

What color is the wire and the stripe on the wire?
