Towing connector adapters bridge the gap between different plug configurations on tow vehicles and trailers. When your truck has a 7-way blade and your trailer has a 4-flat, or you're borrowing a trailer with a different connector style, adapters make the connection possible. We stock adapters for all common configurations including 4-flat, 5-flat, 6-round, and 7-blade in multiple combinations.

What to Know Before You Buy

• Adapting from a larger connector to smaller works fine—adapting up (4-flat to 7-blade) only provides the functions the original connector supports.
• 7-way blade connectors include circuits for electric brakes and 12V charging that smaller connectors don't have.
• Quality adapters use sealed weather-resistant connections—cheap adapters corrode quickly and cause intermittent lighting problems.
• Some adapters require external power connection for certain functions; check the wiring diagram before assuming full compatibility.
