7 Way Blade Truck End to 4 Way Flat Trailer End Adapter

You are looking at a special trailer plug adapter I sell which will allow you to pull a trailer with the 4 way flat plug, even though your truck has the 7 way round plug commonly found on many tow vehicles

This plug consist of a female 4 way connector that the trailer plug can plug into, and 7 way blade plug to plug into the back of your tow vehicle.

Again, the 7 way end fits your truck, and the 4 way end fits the trailer.

This Adapter Should Work for You IF:

Your Towing Vehicle Plug Looks Like This
Your Trailer Plug Looks Like This
