2006 FORD TRANSIT WIRING HARNESS

Where wires are required to be extended, break
in points should only be at existing connector
points and only Ford approved connectors should
be used.
Ford approved link harnesses should be used.
Unused Connectors
The harnesses may have a number of unused
connectors – these are dedicated to other
features and options, e.g. heated seats, but are
not always present depending on level of
harness fitted. Ford do not recommend the use
of these connectors for any other purpose than
that intended by design.
Power Outlet / Cigar Lighter
Both features adopt a 20A fusing strategy. With
a single battery system, continued loading of
these features will lead to battery drain, and risk
vehicle starting. If continuous power is required,
a second battery option should be installed and
the customer connection points, where fitted,
utilized.
4.14.4 Installation and Routing Guides

Anti-Lock Brake System Wiring Harness Routing
The installation and routing of Ford wiring
(including those provided as part of accessory
kits such as trailer tow) have been fully-validated
and have passed the requisite EMC tests. Ford
Motor Company; however, are not responsible
for the vehicle’s EMC immunity when
non-Ford-approved systems are installed.
WARNING: Do not route other wiring
near/close to electrical cables with
the Antilock Brake System and
Traction Control System cables
because of extraneous signal risk.
It is generally not recommended to
hang it off existing looms or pipes.
Wiring must be suitably fixed without any
detrimental effect on other wiring.
Single or bunched looms must maintain the
following clearances:

4.14.5 Electrics for Tow bar
Tow bar electrical system may be ordered as a
13-pin DIN connector, as part of the original
vehicle build.
Where it is required to add trailer towing to an
existing vehicle, and to ensure compliance with
lighting regulations, the appropriate wiring
accessory kit can be obtained from your Ford
Dealer. Fitment of non-Ford trailer tow wiring is
not advisable due to Central Junction Box control
of lighting, and meeting legal lighting regulations.
Contact your local Ford dealer for details of a
harness that connects to the base vehicle
harness. All Transits are provided with a basic
trailer tow interface - this connector is located on
the left hand side of the engine compartment
NOTE: For Van tow bars it is necessary to
connect into the rear lamp unit
For information, there is no trailer tell-tale in the
cluster, and if equipped with the Ford Trailer Tow
module, the vehicle’s rear fog lights are disabled
when a trailer is hitched-up.
A 7-pin trailer tow sub-harness is released by SVO
(part number 6C1V-13B576-A*); currently there
is no 7+7 sub-harness available, but figure E84722
is a proposal detailing the connectivity from the
in-line near the rear of the vehicle. The electrical
schematics for the 13-pin trailer tow system form
part of the workshop manual.

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.

Roof-Mounted Position Light - Front
The lights operate in conjunction with the normal
position lights, driven by Central Junction Box
outputs (Left Hand: pin C2-28; Right Hand: pin
C2-20).
The roof marker lights are fitted as standard to
chassis cab vehicles, except those ordered for
camper use; on cab-van-floor vehicles, there is
a connector located in the area of the A-pillar
above the sun visor on the left and right hand
sides, that will provide the appropriate signals.
To get access the roof trim needs to be
disassembled. Each connector is capable of
supplying a 5W load.
NOTE: The feed for Roof marker lights must
NOT be taken from the side-marker and
end-outline lights signal.

Connectors are already part of the wiring if the
vehicle is medium or high spec. (for example with
electrical side mirrors). The main light switch will
need to be changed for one that includes this
feature. (There are switches with and without
front fog light function).
Connecting to Lighting - Question
and Answers
1.Chassis cab end outline marker lights,
recommended circuit and max amperage –
see lighting load table. There is NO
Ford-released harness for this, as the
end-outline marker lights normally form part
of the float.
2.Van & cab roof mounted rear lamp cluster
turn indicators, recommended circuit and max
amperage – at present there is an SVO
FordTransit 2006.5 (April 2006–)
Date of Publication: 12/2006
4 Electrical
1531E84729 E84718

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.

The software in the PCM responds to the change
of state, so it is recommended that these 3
middle switches be non-latching push button
micro switches. When going from idle to an
elevated RPM the execution of the command
will occur as the button is released. When going
to idle the execution of the command occurs as
the button is pressed.
The final button (the one on the left in Fig. 4) acts
as an ‘emergency’ vehicle engine stop. It is
recommended that this be a red & oversize
non-latching micro switch button. The execution
of this command will occur as the button is
pressed.
All wiring connecting the PCM to the resistance
ladder control box should be shielded & twisted
(33 twists / m) to reduce EMC effects
All resistors should have a tolerance of +/- 5% or
better
Switch contact, connectors & loom (loom
between the green/white wires & the control
box) total resistance must be no greater than 5
ohm max.
The PCM to resister ladder control switch box
loom should not come within 100mm of any other
harness, especially any carrying heavy loads.
Designs which do not require all the button
switches must still have the complete resistor
network with the switches positioned correctly
within the network.
The resistance ladder is acting as a potential
divider
The 220 nF capacitor is used in the circuit to
reduce EMC effects on the system
A suitable two way quality connector should be
used to connect the control box to the two
green/white wires
How to change the default settings
By default, when the feature is first enabled
(either via factory order or via dealer IDS tools),
it will be set to the 3 speed mode of operation
with preset RPM values of 1100, 1600 & 2030rpm
for the 3 speeds.
There are two methods by which these defaults
can be modified:
1.via the IDS diagnostics system at a Ford dealer
(there may be a charge for this)
2.via an inbuilt vehicle ‘learn mode’
Via the IDS system the mode of operation can
freely be changed between any of the 3 modes
of operation, the feature can even be turn off
(disabled). The 3 default RPM speeds can also
be modified.
Via the vehicle ‘learn mode’ the 3 speed mode
& the variable speed mode can be freely
interchanged, however it is not possible to select
the idle up speed mode via the vehicle learn
mode. The 3 default RPM speeds can also be
modified via ‘learn mode’
It is not possible via either method above, to
change the step value of 25rpm per press or the
250 rpm per sec for a held down button, in the
variable rpm speed mode.
Via IDS The RPM Speed Controller menu is under
the tool box tab, then Powertrain, then service
functions, then PCM. The IDS on screen menus
will guide the dealer through the options & setup.
How to enter vehicle ‘Learn mode’
1.Make sure that the RPM Speed controller
switch box is connected but turned off (not
‘armed’)
2.Start the engine (vehicle out of gear & no foot
pedals being pressed, handbrake on)
3.Wait a couple of seconds for the instrument
panel start up diagnostic lights to extinguish
4.Press & release the clutch pedal
5.Press & release the brake pedal
6.Repeat steps 4) & 5) a further four times
(clutch & brake pressed a total of five times
sequentially each)
NOTE: Steps 4) to 6) have to be started within
10 seconds of the engine start
The vehicle should now be in ‘learn mode’
How to Select between modes
1.Enter ‘learn mode’ (see directions above)
2.Arm the RPM speed controller (turn the key
switch to ‘on’)
If the vehicle is already in 3 speed mode (the
initial default):
3.Press & release the brake pedal five times
The vehicle should now be in variable speed
mode. The new settings can be saved & learn
mode exited (see below)
Alternatively
4.Press & release the brake pedal once
The vehicle should now be in 3 speed mode.
The new settings can be saved & learn mode
exited (see below)
Using this method it is easy to change between
these two modes of operation for the RPM
speed controller
NOTE: If the engine stalls out at the initial brake
pedal input then the vehicle was not in, or has
dropped out of ‘learn mode’ & you will have to
restart the procedure.

How to change the 3 pre-set default
RPM values in the 3 speed mode
1.Enter ‘learn mode’ (see directions above)
2.Arm the RPM speed controller (turn the key
switch to ‘on’)
3.Press & release the brake pedal once
4.Press & release the RPM button that requires
re-programming
5.Use the accelerator pedal to rev the engine to
the new desired RPM speed & hold at this
speed (only speeds between 1200 to 3000
rpm can be selected in 3 speed mode)
6.Press & release the same RPM button to reset
the stored RPM speed to the current engines
RPM
7.Release the accelerator pedal
8.Repeat steps 4) to 7) for the remaining RPM
buttons
The 3 RPM speeds should now be
re-programmed to the new RPM speeds. The
new settings can be saved & learn mode exited
(see below)
NOTE: If the engine RPM responds to the initial
RPM button press, then the vehicle has not
entered ‘learn mode’ correctly & you will have to
restart the procedure. If the engine stalls out at
the brake or accelerator pedal inputs then the
vehicle was not in, or has dropped out of ‘learn
mode’ & you will have to restart the procedure.
How to save new settings & exit
from ‘Learn mode’
1.From within the ‘learn mode’ & with the RPM
Speed Control switch box ‘armed’, press the
clutch pedal repeatedly until the engine stalls.
2.Restart the engine & test the new settings,
repeat above procedures if necessary
NOTE: The engine stalling indicates that the
settings should have been saved & the vehicle
has exited from ‘learn mode’. Learn mode
however is very specific that the exact steps are
taken in the correct order & within certain time
limits otherwise the learn procedure fails & it may
take several attempts to get this order & timing
correct & a successful modification from the
default settings.
Some Reasons why RPM speed
Control operation may stop or fail
The RPM Speed control software monitors
vehicle information during operation in RPM
speed control mode & will drop out of RPM speed
control and / or stall the engine should any
adverse signals be detected. For example:
•If the engine temperature becomes too hot
then RPM speed control will stop in order to
protect the engine.
•If the engine oil light illuminates then RPM
speed control will stop in order to protect the
engine
•If the low fuel level light illuminates then RPM
speed control will stop so that the vehicle can
be driven to a refueling point.
•If the vehicle speed exceeds approx 2.5 mph
wile in 3 speed or variable speed modes, then
RPM speed control may stop. RPM speed
control should normally be operated with the
hand brake on, but some uses may require a
low level of vehicle ‘creep’ during RPM speed
control operation. Note that there is no sensing
of the park brake on this version of RPM speed
controller to facilitate this type of operation.
•The software monitors for ‘stuck on’ buttons
on the control switch box, this may result in
RPM speed control being halted. A button that
is held down for too long may be registered
by the software as a ‘stuck’ button.
•The software monitors the foot pedals, if
depressed these may stall the engine if in 3
speed mode or variable speed mode (does
not apply to idle up speed)
•If the control switch box circuitry significantly
exceeds 2110 ohms or there is a short circuit
then RPM speed control will not be possible.
•If a PTO conversion has been attempted on a
vehicle with a non ABS braking system then
RPM speed control will fail due to vehicle
speed being registered via a transmission
speed sensor and / or the need to press the
clutch in order to put the vehicle in gear while
in RPM speed control mode.
4.14.10 Adding Connectors,
Terminals and Wiring
Additional Rear Speakers
NOTE: The connectors on the Instrument Panel
harness (14K024) and the main harness (14401)
are reversed between Left Hand Drive (LHD) and
Right Hand Drive (RHD) vehicles, hence different
sets of terminals/wires are required to cover all
the markets.
