Question:

Hello, Im looking for a trailer lighting adapter that goes from Male 6-Way Round to a FEMALE 7-Way Socket. I see a 6-Way to 7-Way Male to Male but my Tow Dollie already has a Male plug. If one isnt available, is there a 7-Way male to female adapter that I could also use together with the Curt C59HR? I am trying to connect from my RV 6-Way Round Female Socket to a Two Dolly that has a 7-Way Male Plug.

Hey Daniel. I do indeed have an adapter for a male 6-Way Round to a female 7-Way Socket. It's the Buyers Products item # 337TC1067P. It comes with a 8" long cable.

You could also use the Curt Universal 5th Wheel/Gooseneck 7-Way Extension item # C56080 and the Pollak 6-Pole Round Pin item # PK11604 to make your own. The extensions 7' long so you'd have plenty of cable.

What kind of tow dolly do you have?
