The 13 pin Euro type plug and socket is now fitted on most caravans to supply power to all the road lights and ancillary power systems such as fridges and charging systems. All of this in one plug, with a secure twist lock. In 2008 this replaced the N type road lighting plug and the S type Ancillary plug on all new caravans. Converters are available to convert either 13pin to 7 pin or 7 pin to 13 pin.
Below is the wiring diagram for this plug and socket.
|Pin No.||Colour||Function||Cable dia|
|5||Brown||Right tail / Side light||1.5|
|6||Red||Brake / Stop lights||1.5|
|7||Black||Left tail / Side light||1.5|
|9||Orange||12v Permanent power from battery||2.5|

Because pin 12 is not usually used, 12 core cable can still be used to wire this 13 pin plug.
