Great question as I just bought a new A.R.E topper , and I would love to know as well before the guys cut into my wiring harness.

It's hard to see exactly where that wire is but there is a wire up front near the radiator (on top) that is a temperature sensor I believe.
Looks just like that.
Yup like the other said from what i found it's the 3rd break light. was going to install a rear light bar i had from my old truck but never got around to it.
