I just currently purchased the Fire and Ice LED Tailgate Bar, that operates with turn signals, break lights, and reverses lights. I am using my trailer hookup for my break lights, running lights, and turn signals. There is a separate wire for the reverse lights that you have to wire in. I am having trouble getting the reverse light wires hooked in properly. My truck is a 2009 Dodge Ram 1500. Any ideas or suggestions on where I would hook into my truck wiring for the reverse light?
