WHAT IS A 7-PIN PLUG?
Every object that you attach to your vehicle must have electricity nowadays. This ensures that an essential component can
come into operation, namely the lighting. The lighting ensures greater road safety for you and your fellow road users. The
connection between car and object is made by a plug and a matching socket.The most common connections are the 7-pin
and 13-pole plugs. 7-pin plugs are used less frequently nowadays, because they only supply the basic lighting. These plugs
can still be found on older trailers and boat/horse trailers. 13-pole plugs are used with caravans and more modern objects.
A caravan always has a 13-pole connection.

WHAT IS THE DIFFERENCE BETWEEN A 7 AND 13 PIN PLUG?
A 7-pole plug provides only the basic lighting. Think here of fog lights, flashing lights, reverse lights and brake lights. Over
the years, more and more lighting has become compulsory so that the plug can no longer meet all requirements. So the
difference between a 7-pole and a 13-pole plug is that the 13-pole plug can supply more than just the basic lighting.
