    Only One Thing Went Wrong
    The inline plug in unit was easy to plug in. only had one problem, when hooked up I lost running lights to the trailer and one side of car. I checked around and was told my incandescent lights were drawing to much for the system so changed to leds and it works great. Thanks, GEM.
