Recommended 7-way to 4-way Flat Trailer Connector Adapter
Question:
We have a car dolly with a flat four conductor light connector. Our new RV has a 7 connector Bargman receptacle. Do you have a cable for this application?

Yes, we have a few options for a 7 way to 4 way flat trailer connection. One option if you don't need an extension is the Hopkins Adapter 7 Pole to 4 Pole with Tester and Cover, # 47345. This adapter has an LED tester internally to allow you to check your vehicle side trailer wiring functions at the connection.
If you need an extension adapter, I recommend the Wesbar Coiled Adapter - 7-Way RV to 4-Way or 5-Way flat # 787196 for an 8 foot option. For a much shorter extension adapter I recommend the Wesbar Adapter - 7-Way RV to 4-Way or 5-Way Flat - 18" Long, # 707250.
