Well guys we discovered our issue wasnt wiring. Our loading, manger and horse interior lights on our new LQ trailer would only work if plugged into the truck. We assumed they had not been wired into the trailer batteries. Wrong. We were in Oklahoma last week on vacation and decided to call the factory and see if they would let us bring it in to be fixed. They fixed it over the phone. It was a DUH moment for us. There is a fuse in the battery box under the neck and it was blown. We had no idea there were more fuses than what was in the breaker panel in the LQ. Learning curve every day.
