You should be able to find something out on youtube or in the DIY section. I just ran 11" heat tape starting on one side, across the bottom and up the other side. Drilled hole in side to run the wiring (used caulking to seal hole after I ran the wiring). Connected the t-stat and of course the water bottles in the bottom to help keep temps when I need to open the door. I found a rechargeable LED light bar on Amazon that I use in mine. I used velcro tape to attach it. I just recharge it when I need to.
