In this article, we’ll explain everything you need to know about 13-pin trailer plug connections, ensuring your next trip with a trailer goes smoothly.
What Exactly is a “13-Pin Trailer Plug Connection”?
Before we go into detail, let’s clarify what the term “13-pin trailer plug connection” actually means.

Why is the 13-Pin Plug So Important?
The importance of the 13-pin plug lies in its ability to support additional functions beyond just the trailer’s basic lighting. These include:
- Rear Fog Light: The 13-pin plug allows for separate control of the trailer’s rear fog light, significantly improving visibility in poor weather conditions.
- Reverse Light: Separate control of the reverse light ensures safer reversing with a trailer.
- Continuous Power Supply: The 13-pin plug can provide continuous power to the trailer even when the vehicle is stationary, for example, for interior lighting or a cool box.
“The 13-pin plug is crucial for safety. The separate control of the trailer’s lights and the possibility of a continuous power supply make it the standard in modern vehicle technology,” says Dr. Ing. Klaus Müller, an expert in vehicle technology and author of the book “Modern Trailer Technology”.
What Are the Advantages of the 13-Pin Plug Over the 7-Pin Plug?
The 13-pin plug offers a number of advantages compared to the 7-pin plug:
- More Functions: As mentioned, the 13-pin plug enables control of functions that are not possible with the 7-pin plug.
- Future-Proof: The 13-pin plug is the current standard and will continue to be used in the future.
- Compatibility: Modern vehicles are generally equipped with a 13-pin socket.
