The differences between a 7-pin and 13-pin plug: what do you need?
If you want to connect a trailer, caravan or bike carrier to your vehicle, you need a plug that controls the power supply. But which plug is right for your situation? There are two common types: the 7-pin and the 13-pin plug. In this blog, we explain the differences and help you determine which plug you need.
What is a 7-pin plug?
The 7-pin plug is the most commonly used connection for simple applications. This type of plug provides basic lighting and is suitable for trailers and bike carriers without additional features.
Characteristics of a 7-pin plug:
- Suitable for standard lighting (taillights, brake lights, turn signals, fog light)
- Commonly used with small trailers and bike carriers
- No power supply for constant voltage or charging function
A 7-pin plug is sufficient if you only need basic lighting and no additional electrical functions such as interior lighting or a refrigerator in a caravan.
What is a 13-pin plug?
The 13-pin plug offers more features and is often used for caravans and more advanced trailers. This type of plug provides power not only to lights, but also to additional features such as a reversing light and power for accessories.
Characteristics of a 13-pin plug:
- Supports all functions of a 7-pin plug
- Provides additional connections for reversing lights, constant current and charging function
- Ideal for caravans, horse trailers and larger trailers
- Better and waterproof connection by rotary mechanism
If you use a caravan or trailer with additional features, a 13-pin plug is the better choice.
Which plug do you need?
The choice between a 7-pin and a 13-pin plug depends on the type of trailer or caravan you are using. Here are some guidelines:
- Bike carriers and small trailers without additional functions → 7-pin plug
- Large trailers, horse trailers or caravans with additional features → 13-pin plug
Solutions for different plugs
Do you have a 7-pin connector on your vehicle, but a 13-pin plug on your trailer? Or the other way around? No worries! There are adapters available that allow you to easily make the correct connection.
Conclusion
The choice between a 7-pin and a 13-pin plug depends on your needs. For simple applications, a 7-pin plug is sufficient, while a 13-pin plug offers more functionality for more complex applications.
