4.1.3 Circuit Diagram
When designing electrical circuits, or making
alterations, the following must be considered:
•Current rating of wiring, see following
specification chart (Current Rating of Wire
Sizes)
•Any voltage drop in the circuit should not
lower the terminal voltage at consumption
point to below 95% of battery voltage.
•Do not cut into the original loom.
•Additional earth returns should be included to
support new equipment.
•A supplementary circuit diagram and
accompanying instructions should be added
to the Owner’s Information or a separate
Manual supplied with the vehicle for each
unique component.
NOTE: For further information please contact
your local National Sales Company
representative, or Local Ford Dealer.

•Before disconnecting the battery, check
availability of radio key code.
•Fuses – when auxiliary electrical systems are
to be added to the vehicle it is mandatory that
the additional circuit design includes the
necessary fuses.
•The Special Vehicle Option auxiliary fuse box
is recommended.
Refer to: 4.13 Fuses and Relays (page 119).
4.3.4 Fitting of Equipment
Containing an Electric Motor
WARNINGS:
When equipment containing an
electrical motor is connected, it
must be connected via a blocking
diode or relay to prevent “back
Electro Motive Force (EMF)” being
applied to the auxiliary terminal.
When electric motors are to be
fitted, account must be taken of the
potentially high currents that a
motor can draw.
CAUTION: The following must be
observed:
•All motors must be driven via relays with
contacts rated at least 3 times the maximum
rated current of the motor.
•All motor supply circuits must be individually
fused with the proper fuse rating for the
motor.
•All power wiring must be rated for at least 3
times the rating of the motor and installed as
far away as possible from any existing vehicle
wiring.
•All motors fitted should be fully suppressed to
ensure electrical interference does not affect
the vehicle systems.
•Add EMC emissions statement to CE
approval.
4.3.5 Vehicle Electrical Capacity
- Alternator
WARNING: Do not cut into the
alternator wires or use the
alternator as a source to obtain a
'D+ Signal'
An engine run signal is available from the Central
Junction Box by installing a T-piece jumper
harness (Ford Part Number 6C1V-14A411-F_).
Refer to: 4.14 Special Conversions (page 131).
4.3.6 Charge Balance Guidelines
The base vehicle is fitted with a 150A alternator.
It is recommended to conduct a charge balance
calculation in case the conversion comprises a
high number of electrical consumers or high
electrical consumption is expected.
4.3.7 Circuit Diagrams
For circuit diagrams for Auxiliary Fuse Box
Connections and Standard Ford relays.
Refer to: 4.13 Fuses and Relays (page 119).
Full vehicle wiring and circuit diagrams are in the
Ford Workshop Manual.

4.4 Battery and Cables
4.4.1 Battery Information
In order to protect the battery system from direct
ground shorts, a special fuse is incorporated into
the battery positive feed, in the pre-fuse box
under the driver’s seat.
This fuse is not repairable – use only a Ford
replacement part.
Where extra batteries are required on vehicles
with a single battery installation, the battery
disconnect switch (split charge relay) and
associated wiring/hardware — fitted as standard
to vehicles equipped with dual batteries — can
be added.
Batteries – Additional – Heavy Duty
High current consumption may require a
heavy-duty battery or an additional battery.
Factory fitted Special Vehicle Options are available
for heavy-duty and/or extra batteries with the
battery disconnect switch (split charge relay).
The batteries can be retrofitted.
See diagram E74522 - Battery disconnect switch
(split charge relay) circuit.
Deep Cycle Battery (not for use as
primary, start-relevant battery)
A Special Vehicle Option is available. Please
contact your local National Sales Company
representative for availability and details.
•The deep cycle battery is used in conjunction
with the battery disconnect switch (split charge
relay) in applications where power to ancillary
circuits would heavily discharge the main
vehicle battery(s).
•Installation should be under the driver's seat.
When the deep cycle battery is installed, the
battery disconnect switch (split charge relay)
must be used.
•When the Deep Cycle Battery is installed it is
recommended that the Special Vehicle Option
auxiliary fuse box is fed from the customer
connection points.

4.8 Tachograph
The factory-fit Tachograph option uses a
Siemens VDO system. It is recommended,
therefore, that any vehicle that requires a
tachograph is sent to an authorised Siemens
VDO Tachograph Service Centre for system
installation and calibration.
Details of all recommended Service Centers can
be found on Siemens web site. This site also
contains details of current regulations and
tachograph operation.
4.8.1 Legislation
WARNING: All tachographs require
the same wiring connections as this
is controlled by tachograph
legislation.
There are two types of tachograph available, See
below diagrams, E75501 mechanical (MTCO)
and E75502 digital (DTCO). The type of
tachograph required by the customer will depend
on the legislation in the country of use.

Pin Assignment
For detailed information about pin assignments
please contact your local National Sales Company
representative or Siemens VDO directly.
Wiring
NOTE: Not all instrument panel looms contain
tachograph wiring.
The tachograph wiring consists of two parts:
•Speed sensor harness – this is a separate part
which attaches to the instrument panel
harness at the junction of the firewall and floor
pan, close to the centre of the vehicle.
•Instrument panel harness – this contains the
remainder of circuits for the tachograph.
4.8.2 Tachograph Mounting
Standard Ford installation uses a pod on top of
the instrument panel. The tachograph mounts in
the aperture nearest the instrument cluster. Note
the rear mounting bracket in the centre of the
DIN aperture in the below diagram E75503.

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.
