I too mounted my LED strip where the awning meets the camper. But I drilled a hole in the side of the trailer at the end of the light strip. Reason being, on the other side of the hole is where my radio/cdplayer is mounted, as well as where the TV plugs in. There is a shelfe for a DVD player and I have an open outlet. I simply ran the wires through the hole and plugged it in. The LED has a remote, and like many LED sets, have 50 colors to choose from as well as various blinking patterns.
The hole was only 1/2" in diameter sealed with white caulk, hardly noticeable.
Well worth not having to fool around with awning lights and having extension cords all over. im somewhat of a neat freak and don't like a bunch of wires running around. best upgrade i ever did!
