Trailer Connectors

Trailer connectors are essential for safely linking your vehicle's electrical system to the trailer’s lights, brakes, and other auxiliary functions. Whether you're towing a utility trailer, camper, or heavy-duty equipment, Waytek offers a wide range of trailer plugs and trailer electrical connectors to meet every need. 

A 4-way trailer plug handles the basic lighting functions—running lights, left/right turn signals, and brake lights—while a 7-way trailer connector includes additional circuits for electric trailer brakes, reverse lights, or auxiliary power. These connectors are commonly found on SUVs, RVs, and trucks. 

Waytek’s trailer connectors are available in a variety of housing materials including: 

  • Durable black nylon (glass-filled for added strength) 
  • High-impact plastic 
  • Chrome-plated or die-cast metal for heavy-duty use 

 Pair your connector with trailer cable to create a complete wiring solution for trailer lighting and braking systems.
