That yellow wire on my 1979 Fairmont went to the hot side of the starter solenoid. It didn't have plugs like that.

IIRC that's for the rear defroster or in a vert for the top.

Correct.

Yep, power for my rear window defroster, but the end under the hood went to the hot side of my starter solenoid.
