4.12 Exterior Lighting
WARNINGS:
Make sure that the modified vehicle
complies with all relevant legal
requirements.
Do not tamper with the base system
(controlled by Body Control Module and
multiplex architecture) and any feeds
taken from the associated wiring or
controller.
4.12.1 Reversing Lamps
Reversing lamps are activated by the Body Control
Module (BCM) which is controlled by the BCM
high side driver. Accessories that add additional
load, such as back up sounders, connected to the
reverse lamp circuit, should be connected by a
relay. Connecting such loads directly to the
reverse lamp circuit could damage the BCM.
The load on the reversing lamps should not
exceed a total of 3A (42W).
4.12.2 Power for Additional External
Lamps
All power for additional exterior lamps must be
taken through the Auxiliary Fuse Panel with a
suitable switch and/or relay as required.
Refer to: 4.17 Fuses and Relays (page 185).
Refer to: 4.19 Electrical Connectors and
When fitting additional Markers it is recommended
to use LED lamps.

The BCM exterior lighting outputs have shutdown
protection in the event of an overload condition.
If the overload condition is not addressed, the
output will be shutdown permanently to protect
the driver hardware. A dealer visit and/or BCM
replacement may be required if overload condition
is not removed.
4.12.3 Lamps – Hazard / Direction
Indication
NOTE:
If LED indicators are used on the rear of a
Camper and Ford Skeletal Chassis conversion,
the wattage needs to simulate the 21W expected
by the bulb outage detection circuit. If LED
indicators are supplemental to existing system,
then the load resistor may not be required. When
adding extra lamps, the converter must check
they comply to the legal requirements and that
functionality is maintained.
NOTE:
For various vehicles CAT 6 repeater lamps
must be fitted. See legislation for full details.
Check with your local Ford Dealer or National
Sales Company representative.
The standard system configuration each side:
•
1 x Front Indicator 21W - max load 27W.
•
1 x Rear Indicator 21W - max load 27W.
•
1 x Side Repeater (Mirror Mounted) either CAT5
(5W) or CAT6 (16W). The whole mirror
assembly needs to be changed if moving from
CAT5 to CAT6.
