7 Way Round to 5 Pin Flat Trailer Plug Light Adapter RV Connector Boat RV

Part Number - F75F

You are looking at a special trailer plug adapter I sell which will allow you to pull a trailer with the 5 way flat plug, even though your truck has the 7 way round plug  found on some tow vehicles

This plug consist of a female 5 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 5 way end fits the trailer.
