Hey Dave, what final route did you take to get the wires run back up to the light? I saw earlier where you had run them behind the window seal, but you had an ingress of water after that. Did you get your leak sealed? I don't mind drilling into plastic, as it is not needed for structural integrity. Routing the wiring around all the glass in our units looks like it would be tough.My switches are mounted in the plastic on the side just below the cupholders.
