What is a 13-pin plug? - TRALERT®
A 13-pin plug is used to connect, for example, a trailer or caravan. With the 13-pin plug, the trailer's lighting will function. In addition to lighting, the 13-pin plug also allows for connecting additional functions. Think, for instance, of the motor for the tipping function of the trailer. Besides a 13-pin plug, there is also a 7-pin plug available on the market.

Difference with 7-pin plug
Naturally, there are differences between the two connectors. A 7-pin connector is intended to provide the trailer with basic lighting. A thirteen-pin connector ensures that the trailer is equipped with more lighting. By basic lighting, we mean, for example, turn signals and brake lights. In addition to the possibility of connecting lighting such as reverse lights, you also have two positions free. These positions can be used in the caravan world for a refrigerator, and in the trailer world for the tipping function.
Two variants
There are two different types of 13-pin connectors: the Jaeger connector and the Multicon West connector. Both connectors differ from each other. The Jaeger is standardly used with German car brands such as Mercedes, Audi, and BMW. It features a bayonet connection, which ensures that the connector fits more securely. When you want to connect a thirteen-pin Jaeger connector to a 7-pin connector, you will need to use an adapter adapter. Make sure to remove the adapter when not in use to prevent moisture ingress.
The second option is the Multicon West plug. The Multicon West plug is standard on cars from other countries. This connection fits both a 7-pin and a 13-pin plug. It can also be used for both functions. The connection can be useful when your trailer still has an ‘old’ 7-pin connection. What is important to know is that a Multicon West plug does not fit into a Jaeger socket. The reverse is also true.
