2006 FORD TRANSIT relay

The fitment of the Special Vehicle Option auxiliary
box will provide a power source for the relay
(although connection to the engine run pin is still
required).
Where connections are already made to the
engine run signal, it is vital that these connections
remain connected. In this instance, a suitable 'Y'
Jumper link should be used to tap out of the
connection.
Refer to: 4.13 Fuses and Relays (page 119).
If a positive (+12V) engine run signal is required,
this is possible by using the relay contacts to ‘pull
in’ 12V (preferably an ignition feed, KL15)

WARNINGS:
Under no circumstances should the
CAN bus be tampered with. This
may lead to failure of safety critical
components such as Anti-lock
Brake System.
Do not use connectors which cut
through the outer covering and into
the core wire
CAUTION: Only use Ford approved
connectors
Cutting into vehicle wiring is not permitted
because:-
•The base vehicle specification is unsuitable
for incremental loads except in conjunction
with Special Vehicle Option Auxiliary Fuse Box.
•Long term risk of a faulty connection
developing.
•Potential fire risk from over-loading.
All connections into existing wiring must be
permanently insulated. Exterior connections must
be water-proof.

Trailer Tow Connectivity - Trailer Tow, 12N & 12S Sockets
DescriptionItem
13N490 HarnessA
TubesX
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.

4.14.8 Additional Vehicle Signals
/ Features
Reverse Signal
A reverse signal is available on the tail light
connector. In order to avoid electrical issues due
to leakage, and to ensure connector
compatibility, a mating connector with
seals/plugs and pre-crimped wire & terminal
should be used. For Additional information refer
to Adding Connectors, Terminals and Wiring in
this manual.
NOTE: It is not recommended that signal is used
to drive auxiliary equipment directly – a relay (max
300mA) should be used. The existing reverse
light load is close to the threshold and is
hard-wired through the Central Junction Box for
current sensing to generate the appropriate CAN
message.

Pin Brake Light on Trailer Tow in-line connector at Rear of Vehicle
DescriptionItem
Third Stop LightPin 8
*If an existing third brake/stop lamp is already
fitted, or if the power exceeds 21W, an
intermediate relay must be used.
For Van, Bus and Kombi, the signal should be
derived from the 6-way connector to the rear
light assembly, pin 4.
Additional Position Lights at the Rear
of the Vehicle
The feed for position lights only at the rear
(bottom / top) can be taken from the licence plate
lighting connectors: left and right. For the correct
pin, please refer to Figure E84727; the maximum
load is 10W per side.
NOTE: Any additional position lights should be
taken from the licence plate lights, and no other
source.
In order to avoid electrical issues due to leakage,
and to ensure connector compatibility, a mating
connector with seals/plugs and pre-crimped wire
& terminal should be used. See Adding
Connectors,Terminals and Wiring.
NOTE: Position lamps (front and rear) only
function with the lighting switch in positions 1 or
2; however, the same bulbs are also used for the
parking lamps. There are two operating modes
for the latter, both with the ignition key removed.
1.Ignition off, master light switch to position ‘P’:
all 4 lamps are on.
2.Ignition off, master light switch off, move turn
indicator stalk to either left or right position (and
leave in): tell-tale and chime will operate briefly
and parking lamps (2) on the side selected will
be on.
The position and parking functions operate
independently.
When the position lights are extinguished, the
side marker and end-outline markers turn off
simultaneously, in line with InterRegs No 48, which
states the following:
5.11 - The electrical connections must be such
that the front and rear position lamps, the
end-outline marker lamps, if they exist, the
side-marker lamps, if they exist, and the rear
registration plate lamp can only be switched on
and off simultaneously. This condition does not
apply when using front and rear position lamps,
as well as side-marker lamps when combined or
reciprocally incorporated with said lamps, as
parking lamps and when side-marker lamps are
permitted to flash.

Licence Plate Lamp Connector
Side (and End Outline) Marker Lights
Side-marker and end-outline lights should be
installed in-line with the relevant vehicle
regulations. Both types of lamp are driven from
the same output on the Central Junction Box
(pin C2-16).
The number of lights per side that can be
supported (without the need for relay-activated
feeds) is typically 4 lights, provided the total load
does not exceed 20W, for example:- a total
additional vehicle load of 40W. There are two
ways to obtain this signal:
1.The chassis cab / cab-van-floor camper
underbody harness (14406) has 2 in-line
breakout connectors – in the middle of the
vehicle and in the area of the rear axle – that
provide feeds to these lights. Each breakout
will support a 10W load, and will connect with
a Ford jumper harness (part number
6C1T-15B484-A*) that provides connectors
to each side of the vehicle for side marker
lights (one harness connects to one left and
one right side marker light, for example:- 5W
per side).
NOTE: These breakout connectors are only
available on cab-van-floor LWB (2 pairs) and
MWB (1 pair) and chassis cab LWB (2 pairs) but
not on chassis cab MWB.
2.Alternatively, and/or in addition to, the feed
for the side-marker and end-outline marker
lights can be taken from the connectors to
the licence plate lights (2-way connector). see
also Adding Connectors, Terminals and Wiring.
NOTE: The feed for side-marker and end-outline
lights must NOT be taken from the position lights
signals. (The Central Junction Box output
provides power for the left and right position
lights, other lights including trailer tow, and will
NOT accept any additional load). The
side-marker and end-outline lights signal must
NOT be used for the roof marker lights.

harness that provides roof-mounted rear turn
indicators, powered via relays. This should be
used in conjunction with SVO fusebox.
3.Chassis cab LED rear lamp cluster
replacement recommendations, especially
turn indicator relay implications – see lighting
load table. Generally the use of LED equivalent
lighting systems reduces the electrical load on
the vehicle; however, special care needs to
be taken with respect to any change to or
addition of turn indicator lights. Depending on
the current requirements of the LED(s)
compared to the bulb it is replacing, a ballast
resistor may be required, if not already
integrated into the LED lamp assembly.
Without this, bulb outage detection for turn
indicators will be affected, which is a legal
requirement.
Additional turn indicators must be powered
through relays (max 300mA), driven by existing
turn lights. The maximum load that the Central
Junction Box can drive is 3 x 21W per side (front,
rear and CAT 6 turn indicators); but even if the
vehicle is not fitted with the CAT 6 lights, the feeds
for these should not be used as the Central
Junction Box would need reconfiguring, which
could have safety as well as functional
implications.
4.Special Vehicle Option beacon switch: wiring
locations, circuit diagrams and max amperage
– see Special Vehicle Option fuse box
schematic (max current is 15A); there is
provision for the Special Vehicle Option beacon
switch in an empty switch location on the
instrument panel.
5.Rear loom connector detail location and supply
details for retro-fit loom extension for
example:- when extending a medium wheel
base, long wheel base or extended frame
overhang, what connectors do they use to
make a plug and play loom extension? – for
chassis cab vehicles, there is an Special
Vehicle Option extension loom for rear lamps
(part number 6C1V-14408-A*). There is not, at
present, a similar loom for Van, Bus and
Kombi's, although the appropriate mating
connector is now tooled, so this would be
possible.
Miscellaneous Systems
Handbrake on - Cluster Warning Light -
Unless the vehicle is specified with options that
drive the handbrake warning light (for example
ESP, Australia market), the components making
up this system are not fitted. We do not
recommend installation of this feature as an
aftermarket addition. There are several reasons
for this:
1.Not all circuits carry the requisite wire as a give
away:
•The wires might be part of the main vehicle
harness (14401) even if not used – for example
camper vehicles are normally ordered with
power mirrors, and the wires will be present
as a give-away.
•The seat pedestal harness (14K076), however,
is vehicle specific – if the handbrake is not part
of the specification, it will not be present or
give-away. This harness would need to be
changed to the compatible part that also
includes the handbrake warning light circuit.
2.The handbrake switch (part number
2F2T-15852-A*) together with its short jumper
harness (6C1T-15K857-A*) would need to be
obtained and fitted.
3.The handbrake warning light is in all clusters,
but unless the vehicle config. parameter
“parking brake switch” is set, the Central
Junction Box will not read this input, and hence
NO CAN message sent to the cluster.
Reconfiguration can only be done at a Ford
Dealer.
NOTE: If a vehicle already has a handbrake
warning light in the cluster, or one is installed as
per the Ford design, it is not possible to utilize the
wire from the handbrake switch as part of an
interlock circuit (this is a pull up resistor input that
provides a wetting current of 20mA – anything in
excess of this, for example through additional
circuitry, will almost certainly damage the Central
Junction Box). If there is no handbrake switch
installed, it would be possible to add one and
utilize this as part of a separate circuit, up to a
maximum current of 500mA through the switch.
Reverse Sensors (Rear Park Aid
Module)- The factory-fit option is a CAN-based
system, but for Van, Bus, and Kombi vehicles
only. Stand-alone systems can be installed (for
example for chassis cab conversions), but would
need to utilize the PTA line of the radio if muting
is required.
Fuel Fired Heater (FFH)- Add FFH: wiring is
only present (give-away) in certain harnesses.
There was an aftermarket kit available for this
system on current Transit, which could probably
be “updated” to suit V347/8.
Fuel Fired Heater (FFH) - Programmable
FFH: this utilizes a timer/control module mounted
to the Instrument Panel, which necessitates
having the correct Instrument Panel harness
fitted. Retrofit of this would be a difficult.
For both systems, the appropriate 6C1T-14K132
harness would be required (suffix -A* for
Programmable FFH, and suffix –B* for Add FFH).
Central Locking
Locking is controlled by the Central Junction Box
module. There is current sensing on certain
locking circuit pins as part of the security system
– if these are tampered with, locking cannot be
guaranteed.

However, it is possible to add an additional lock(s)
– see also the section covering the ‘third button
on key fob’ – but only by utilizing relays (the
electric locks are operated by surface mounted
relays in the Central Junction Box – these are
only capable of powering one lock each, in
addition to which the output of these devices is
current-sensed to check it is within minimum and
maximum limits: I) to verify operation, and ii) as
part of the security system). For camper vehicles,
the Central Junction Box is configured for a
chassis cab vehicle.
Depending on functionality required, the pins
used will emulate the basic locking/unlocking
operation of an existing door. Note, however,
that any additional locks will not be covered by
the vehicle alarm or operate Central Junction
Box controlled lighting, etc. It would be necessary
to splice into either the Central Junction Box
connector or the in-line connector for the door
jumper harness. The coil of the relay (max.
300mA) should be added across the relevant
pin and ground (i.e. one relay for lock all, one
relay for driver door unlock etc.)
The use of Ford Transit lock mechanisms is
strongly recommended as the Central Junction
Box is designed to drive these latches for the
correct amount of time.

Locking Configurations- The following list
details specific locking scenarios that have been
noted by customers:
1.Raid locking or drive away locking for taxi and
parcel van usage – this is a configurable
parameter in the Central Junction Box (Ford
Dealerships can set this).
2.Slam locking – this is a configurable parameter
in Central Junction Box (marketing want to
sell this as an option, therefore dealerships
can only switch off this feature, but not switch
on).
3.N1 lock reconfiguration into M2 locking, i.e. no
deadlocks – this can be reconfigured to be
central-locking only by a Ford Dealer (via
Dealership hotline).

5.3.1 Load Compartment Interior
Lining
Do not damage the lock or latch system
(electrical cables, release system) when applying
interior lining.
WARNING: Plan fixing points for
other fitments such as racking to
ensure through bolting can be
achieved. Fixing to the lining
material may be inadequate for
normal safe operation of the vehicle.
The additional weight of the linings on doors may
require additional reinforcements to the door and
pillar at the hinge and check mechanism.
5.3.2 Security, Anti Theft and
Locking System Security
NOTE: It is not recommended to alter the
locking system.
However, in case a modification is required for
the conversions, please consult the Vehicle
Converter Advisory Service [email protected].
To avoid locking system security complications,
it is recommended to discuss with the local Ford
dealer prior to modifications taking place.
The Central Junction Box is designed to work
specifically with the Ford Transit lock and latch
mechanisms and therefore drives latches to lock
and unlock for specific time periods. Additional
power locking functionality should be based
around the use of additional Ford Transit latch
mechanisms. Additional latches can be driven
via relays connected in parallel with existing
latches.
On Chassis Cabs fitted with a high-level
Passenger Junction Box, the cargo door latch
driver is not used by the base vehicle and can
be used by Body Builders wishing to add power
locking capability to the vehicle load space. This
latch can be controlled via the driver's door key
barrel or the cargo unlock button on the remote
key fob (dependent on vehicle configuration).
The following figures outline the areas in which
it is not advisable to drill:
