What are these connectors?

I found two connectors during my engine swap that I need to know what they are. They're located up near the firewall on the passenger side near all the AC stuff in that wiring harness. There's two connectors. One is a two wire connector, one wire green, the other black. The other connector is a single wire connector with a red wire. The connectors are a long type connector, not like most of the shorter connectors on the engine. The reason I need to know what these are is because the red wire connector looks quite fried and the two wire connector has some melted spots on it which I figure is from the fried red wire. Any help would be greatly appreciated. Thanks in advance.

86,

The dark green wire is likely power to the AC compressor clutch, and the black wire in the same connector is the clutch ground.

The single red wire could be the AC HIGH fan relay power feed, or could be the power to an underhood lamp.

Thanks for the help. I hope that's all they are. My AC has basically been eliminated and all the cycles work for my heater so if that's it then it's no big deal. I don't have an underhood lamp. Never did have one since I've had the car anyway. So I guess if that is what it used to go to then that's no big deal either.
