Hello all: new to the Hi-Lo world, having bought a 2002 22T mid summer. Have used it a couple of times dry camping and the family loves it, especially my 2 girls, who don't have to drag a shovel off to the woods to do their business. Anyway, I'm wondering how to replace the driver-side brake light assembly after the plastic brackets holding the license plate broke. I have the replacement assembly and can only guess that I have to use a square bit open the "skin" of the trailer and expose the wiring I need access to. Any thoughts would be helpful. Thanks, Mike
