Wondering what this wire goes to 73-80 wiring loom

[Chlsnk]

I am going to swap over front clips from my 84' to the older 74' front end this Friday. And before diving into this project I figured i'd do the once over of all the parts I have and while looking at my wiring loom for the headlights. I noticed there is a lager gague green wire that is cut off mabey 2 feet from where it goes into the block that plugs into the firewall.. Could anyone tell me what this goes to?




Also on a unrelated note was there any years 73-80 that had a under hood light that would come on when the hood was opened. My hood has a cut out for what looks like where a light would go.
