Update:. I hooked up 12g wire to the junction box, ran it through a wire cover, and snaked it along the I-beam. I connected it to my backup lights and camera, plugged the pigtail to the truck and put it in reverse. Both the lights and camera kicked on! Next, I will go back under the camper and permanently attach the wire to the I-beam. Thanks for all your help. My 70 year old body is sore from doing all that crawling around under the camper, but I am ticked pink that it all works. Thanks for your help!
