Electrical socket for trailer
The vehicle is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10 is
302
only powered when the engine is running. The

charge wire (pin 10) charges, for example, a
caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13, should
never be connected to each other to avoid
overloading the electrical system.
If the trailer has a 7-contact connector, you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available.
