Trailer sockets and plugs create the electrical connection between your tow vehicle and trailer for lighting, brakes, and auxiliary circuits. These connectors handle brake lights, turn signals, running lights, and—on larger connectors—electric brake signals and 12V charging circuits. We stock sockets (vehicle side), plugs (trailer side), and mounting hardware in all common configurations including 4-flat, 5-flat, 6-round, and 7-blade.

What to Know Before You Buy

  • Match connector type to your needs: 4-flat handles basic lights; 7-blade adds electric brakes, 12V charging, and backup lights.
  • Sockets mount to the tow vehicle; plugs wire to the trailer—verify which component you're replacing.
  • Quality connectors use sealed weather-resistant designs that prevent corrosion and intermittent connections.
  • OEM-style connectors include vehicle-specific brackets; universal connectors require custom mounting.

Replacing a damaged connector or upgrading to a 7-blade system for electric brakes? We can help you gather the right components.

Free shipping on most orders $99+ (US lower 48). Expert support and 90-day returns.
