If a caravan is to be connected with a 13-pin Jaeger system plug, the towing vehicle must be equipped with a 13-pin socket suitable for the trailer plug (from the GM European Aftersales range) in place of the 7-pin socket.  

A caravan with a 13-pin plug Multicon system plug can be connected directly to the 7-pin socket. If, however, current is required for the caravan interior illumination and refrigerator, the towing vehicle must be equipped with a 13-pin socket suitable for the trailer plug (from the GM European Aftersales range) in place of the 7-pin socket.  

Parts:  

The Aftersales Department stocks three different socket versions:  

 

1  Socket, 13-pin, Multicon system, 90 397 297 / 17 36 333, suitable for Multicon plug and 7-pin plug, system DIN-ISO 1724.  

2  Socket, 13-pin, Jaeger system, 90 392 256 / 17 36 326, (corresponds to DIN design 72 570).  

3  Socket, 7-pin, DIN-ISO 1724 system, 90 103 411 /17 36 330, suitable for all trailers except caravans equipped with Jaeger system plugs.
