This question comes up about once a month where people have removed their engine and found a spare
green single wire connector left over when the engine was refitted. Everything works but they want to know.

Here is the green shrouded connector. It's a standard spade receptacle with a plastic cover. 

The reason why you can't find a home for it, yet everything on your car works, is because you don't have AC.

On a car with air conditioning, the connector joins to the AC pressure switch, however, the connector
is part of the wiring loom even if you don't have AC. The other green connector in the above photo
is connected directly to the air conditioning compressor in the engine bay.

No AC means no compressor so you just have 1 spare green connector.

Just tie it up out of the way and think nothing more of it.
