Electrical socket for trailer
The v
ehicl
e is fitt
ed with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. With the engine
running, electrical devices on the trailer re-
ceive power from the electrical connection
(pin 9 and pin 10 on the trailer power plug).
If the system detects that a trailer has been
connected electrically, the electrical equip-
ment on the trailer will receive voltage
through this connection (pins 9 and 10). Pin 9
has a permanent live. This powers, for exam-
ple, the trailer's interior lighting. Electrical de-
vices such as a fridge in a caravan only re-
ceive electrical power if the engine is running
(through pin 10).
The earth wires, pin 3 and pin 13, should not
be connected to each other to avoid over-
loading 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.
Trailer cable
Always secure the trailer cable to the towing
vehicle correctly. Leave a little bit of slack in
the cable for turning. However, ensure that
the cable does not rub off the ground while
driving.
Trailer rear lights
Check the trailer rear lights to ensure they
work correctly and remain legal. Ensure that
the trailer does not use more than the maxi-
mum power
