PinsY
The Ford trailer tow system is designed to
support one primary set of direction indicators
installed on to the trailer (left hand side and right
hand side). If additional direction indicators are
required, for example for tall horse boxes, these
should be driven using separate relays with the
coils being energized via the respective primary
direction indicator feeds, and power to the bulbs
being derived from the KL30 (B+) line.
WARNING: Depending on the
vehicle's lighting configuration, the
Central Junction Box (CJB) will not
support trailer direction indicators
wired directly to the vehicle's
direction indicators. If this is
attempted, the relevant CJB circuits
may shut down or perform illegally.
The Central Junction Box (CJB) does not
support the incremental load of powering side
marker lamps on a trailer, if these are required
they should also be driven using separate relays,
as above.
NOTE: The trailer detect circuit is part of the
Ford Trailer Tow module – it is not implement
able separately – and is only operational on
vehicles fitted with power locking.

Van, Bus, Kombi Ground Points
CAUTIONS:
Only use the ground points indicated.
Using alternative points may affect
the vehicle integrity.
Make sure that all ground points are
tightened to the correct torque.
Ground wires should be brought back to the Ford
ground points provided, please refer to the
following figures. For very high current users, it is
recommended that the ground connection is
made directly to the ground point close to the
battery ground point.
