7 Way Round Pin Truck End to 7 Way Round Blade Trailer End Adapter
Part Number - R77F
You are looking at a special trailer plug adapter I sell which will allow you to pull a trailer with the 7 way blade plug, even though your truck has the 7 way pin plug commonly found on semis
This plug consists of a female 7 way blade connector that the trailer plug can plug into, and the 7 way pin plug can plug into the back of your tow vehicle.
Again the 7 way pin end fits your truck, and the 7 way blade end fits the trailer
The plug consists of a female 7 way blade connector that the trailer plug can plug into, and a 7 way pin plug can plug into the back of your tow vehicle.
