If you want to use any PlasmaGlow Truck Products, like the Fire & Ice Tailgate Bar or Mud Flap Kit, that utilize the 4-pin trailer hitch plug and pull your trailer at the same time, your only option was to hard-wire your lighting accessories.
The PlasmaGlow 4-Way Trailer Hitch Adapter Splitter will allow you to plug up to 4 products into the trailer hitch plug on your truck without having to do any complex wiring. It will fit any truck with a 4-pin flat trailer hitch adapter. If you have a round trailer hitch plug, you can get an adapter to change to to a 4-pin at most auto parts stores.
