Why Use a Dedicated Wiring Kit for the Mercedes GLS?

The Mercedes GLS is a full-size luxury SUV built for comfort, space, and power—making it an ideal candidate for demanding towing applications. A vehicle-specific towbar wiring kit ensures that all necessary lighting functions—including brake lights, indicators, and reverse lights—work flawlessly, while maintaining full compatibility with the GLS’s CAN-bus system and advanced safety features.

7-Pin or 13-Pin: Which Wiring Kit Do You Need?

Depending on your trailer or equipment, choose between the following options:

  • 7-Pin Wiring: Best for simpler trailers or carriers requiring only standard lighting.
  • 13-Pin Wiring: Ideal for caravans and advanced trailers needing power for onboard systems, reverse lights, or battery charging.
