You are looking at a special trailer plug adapter I sell which will allow you to pull a trailer with the 5 way round plug, even though your truck has the 4 flat plug commonly found on most tow vehicles
This plug consist of a female 5 way round connector that the trailer plug can plug into, and 4 way flat plug to plug into the back of your tow vehicle.
Again, the 4 way flat end fits your truck, and the 5 way round end fits the trailer.
This Adapter Should Work for You IF:
