Extra wire needs a home

I recently inherited a 1977 corvette. I’ve been going through the vehicle taking note of everything and learning this vehicles ins and outs. I stumbled upon this wire coming off of the alternator’s harness. I’m sure it goes somewhere but I cannot put my finger on where. The alternator seems to be charging just fine at slightly over 14V.

(And Yes, I will be replacing ALL of the wire connectors that are out of place in this photo)

First guess, That green wire goes to the temp sending unit.

Might that be what this is??

That would be it

Hit the nail on the head there.

Thank you for the help!!!
