Loose wire

[Tony MB]

Recently took the bumper off my CLK to fit new headlight washers.....With the bumper off I found on my offside front fog light wire/plug has another wire/plug branching off with a cap on it....Anyone know what it's for ?

The one at the very end? Isn't that the outside temp sensor?
