Towcar Electrics - Swift Tourer Owner's Handbook Manual

Tow Car Electrics
In all cases, The Swift Group assumes that the
tow car harness and electrics have been fitted
with the specific requirement of connection to
a caravan, which may contact AL-KO trailer
control (ATC), a 12V powered fridge and
charging circuits.
Most modern retro-fit towbars contain a relay,
located somewhere within the boot of the tow
car, which may have a selectable power output
for the fridge supplier.
If a customer is experiencing issues with the
fridge supply it is possible the relay requires
and adjustment and they should contact
their tow vehicle electrics installer or an auto
electrician to verify the installation.
Caravan 13 Pin Connection - care advise
All caravans since 2008 have been supplied
with a 13 pin plug to connect to the towcar.
The 13 pin plug has an inner ring assembly
that is independent from the outer body.
Under normal circumstances the inner ring and
the outer body will be locked in one position
(see fig 1).
When the plug is first inserted in the socket
body ensure that the locating protrusion (key)
matches the groove (keyway) in the socket
body. The outer body can then be rotated a
full 90 degrees clockwise until a click is felt
or heard, at this point the cover flap can be
allowed to fall over the circular surface of the
plug top.
To remove the plug it is important to rotate the
outer body a full 90 degrees anti-clockwise,
again until a click is heard or felt before

withdrawing the plug from the socket. This will
ensure that the inner and outer parts of the
plug are returned to a locked condition.
Warning: If the connector is not fully
rotated anti-clockwise prior to removing it
from the socket it is possible that the inner
ring will become 'floating' and may result
in a condition where the protrusion will be
incorrectly aligned (see fig 2 & 3).
If this situation does occur then it can
be corrected by entering the edge of the
protrusion on the plug into the groove in the
socket (see Fig 8) and rotating the plug body
anti-clockwise until a click is felt. This process
will re-establish the lock between the inner and
outer parts allowing the correct insertion of the
plug into the socket.
NOTE : Customers should note that the
towbar and towcar electrical socket will be
checked from the 1st January 2012 as part of
the standard MOT regulations, under directive
2009/40/EC. This not only applies to tow
