What is a 13-pole plug?
A 13-pole plug is used, for example, to connect a trailer or caravan. The lighting on the trailer works with the 13-pole plug. As well as the lighting, the 13-pole plug also offers the possibility of connecting extra functions. Think of the motor for the tipping function of the trailer. In addition to a 13-pole plug, there is also a 7-pin connector within the market.
Difference with 7-pin connector
Of course, there are differences between the two plugs. A 7-pole plug is intended to provide the trailer with basic lighting. A 13-pole plug ensures that the trailer is equipped with more lighting. Under basic lighting we mean for example indicators and brake lights. In addition to the possibility of lighting as reverse light you also have two positions available. These positions can be used in the caravan world for a refrigerator, for example, and in the trailer world for the tilt function.
There are two different types of 13-pin plugs. Namely the Jaeger plug and the Multicon West plug. Both plugs differ from each other. The Jaeger is used as standard in German car brands such as: Mercedes, Audi and BMW. It is fitted with a bayonet connection, which ensures that the plug is more solidly attached. If you want to connect a 13-pin Jaeger plug to a 7-pin plug, you will have to use a Adapter from. Be sure to remove the adapter when not in use. Otherwise moisture may get in.
The second option is the Multicon West plug. The Multicon West plug is standard on cars from other countries. This connector fits both a 7-pin and a 13-pin plug. It can also be used for both functions. The connection can come in handy when your trailer still has an 'old' 7 pin connector. What is important to know is that a Multicon West plug does not fit in a Jaeger socket. The other way round is also the case.
The wiring diagram also looks different when comparing the two different 13-pole plugs. The wiring diagrams of the two different systems are shown in the illustrations below. If you have any questions, please do not hesitate to contact us.
