2006 FORD TRANSIT wiring

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.

Battery Rules:
•Batteries in parallel must be of the same type
and capacity.
•Starter and deep cycle batteries may only be
mixed through an isolator.
•For External charging of batteries ensure that
the maximum voltage of 14.6V is not
exceeded.
NOTE: Deep cycle batteries can be drained but
high loads can damage them. Always observe
circuit set-up outlined in diagram E74522 -
Battery disconnect switch (split charge relay).

Pull-in us actuvated within 70 ms of switching to
key position II
Pull-out is activated when switching to key
position I, or 0, and in key position II when no
engine run signal is sensed within 120 secs.
It is not possible to change state within 500 ms.
Removal of the Battery Disconnect
Switch (on twin battery models) and
wiring of batteries in parallel for high
current applications.
For vehicles equipped with a twin battery system,
wiring of the two batteries in parallel is not
recommended. If higher current is required,
680Ah batteries can be fitted (or a deep cycle
battery in lieu of the non-start relevant battery
only). Where a single passenger seat is fitted,
further batteries (1 or 2) can be installed in the
pedestal and added in parallel to the
non-start-relevant battery, although due
consideration then needs to be given to
increased current availability in the event of a
short circuit. Additional batteries should not be
installed under a passenger bench seat.
if this requirement is imperative, it would be
possible to disconnect the battery disconnect
switch and put the start-relevant and
non-start-relevant batteries in parallel using a
shorting bar (available from the Ford Delerships,
part number 6C1T-14A439-A*). There is one
important consideration when replacing the
battery disconnect switch with a shorting bar:
•Where the vehicle is configured for
twin-battery operation, the Central Junction
Box will detect if the battery disconnect switch
is missing (or has been removed), or the
mating connector short-circuited, and although
the vehicle will be functional, Diagnostic
Trouble Codes will be generated that will
flag-up during service. Hence if a shorting bar
is fitted, the vehicle needs to be reconfigured
(via the Dealership and Dealership Hotline).
Single to Dual Battery Conversion
For vehicles equipped with a single battery, it is
possible to upgrade to a twin battery system -
the connector for the battery disconnect switch
is present on all vehicles. In addition to
reconfiguring the vehicle for twin battery
operation (at a Dealership), the following battery
cables and components are required:

If a requirement exists (camper conversions for
example), it may be viable to order vehicles
installed with a single battery, a battery disconnect
switch, and a kit of harnesses – detailed above –
to be fitted by the installer.
Where required, e.g. for camper conversions,
gas-sealed battery boxes (with exterior venting)
are available. Ford part numbers:
6C1T-10N669-A_ (lefthand); 6C1T-10N669-B_
(right hand); 6C1T-10N725-A_ (lid).
The battery disconnect switch isolates the
auxiliary battery/batteries from the rest of the
base vehicle electrical system when the engine
is stopped.
The battery disconnect switch, together with
associated wiring and hardware, can be fitted as
part of an accessory kit (available from your local
Ford dealer) in the pre-fuse box.

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.

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.

4.9.2 Possible Accessories
Electric Antenna- Activation line, pin B2
(Switched Accessory +) is switched: 0 Volts when
the radio is switched off and +12 Volts when the
radio is switched on.
Auxiliary Input- Accepts a line-out from a
personal stereo or digital media player. This can
be supported by left channel pin C5 (+) and right
channel pin C11 (+) with a common ground, pin
C6, wired to a jack plug socket.
Audio Mute- There is a requirement under the
Health and Safety Machinery Directive to mute
the radio when machinery is in operation - this is
necessary to hear audible alarms and signals.
Pin B5 (C3-5 on the electrical schematic) on the
FAKRA interface should be used for this. In order
to avoid electrical issues due to leakage, and to
ensure connector compatibility, a connector
insert and a pre-crimped wire and terminal are
available as part of a wiring accessory kit, should
be used (Kit Part number KT6C1V-14A411-L*).
NOTE: When this line is pulled low (ground),
radio / CD sound is muted. However, there is no
wire present in the harness as this function is
normally communicated through the CAN bus.
Refer to: 4.14 Special Conversions (page 131).
(Adding Connectors, Terminals and Wiring)
After Market Hands Free Telephone Kit
(Non CAN-based)- Power should be supplied
via a fused battery line and activated by the
accessory line, pin A16. The mute line from the
phone is connected to Phone Transceiver Active,
pin B5. The audio output from the phone kit
should be fed into pins B1 (+) and B7 (–). The
phone audio is then amplified and diverted
through vehicle speakers.
Refer to: 4.14 Special Conversions (page 131).
Adding Connectors, Terminals and Wiring (for
Phone Transceiver Active / Speaker Terminals
and Wires).
After Market Audio / Navigation (Non
CAN-based)- Power should be supplied via a
fused battery line and activated by accessory
line, pin A16. Auxiliary input is connected as per
above.
NOTE: Note: Vehicle speed and reverse are
now CAN messages and supplied via the vehicle
multimedia bus, A9 (+) and A10 (-). There is no
hard wired Vehicle Speed Signal or reverse signal
available.
Additional Rear Speakers- Camper
vehicles, typically, are only equipped with
speakers in the front doors, in which case at
end-of-line the vehicle will be programmed for
just the front speakers and the fade function
disabled on the radios. If the radio is set for four
speakers, and those at the rear are absent, a
fault code will be flagged. The vehicle would need
reconfiguring at a Dealer once speakers are
installed. The radio will output 17W per channel
(left and right); a wire size with a CSA of 0.75 is
recommended.

Rear speaker wiring is always present in the
instrument panel harness (14K024), but not
necessarily in the harnesses (14401 and
14405/14A005) that then take the signals to the
rear speaker locations
For connecting two additional rear speakers, we
recommend utilising the 57-way connector, which
is located behind the glove box above the Central
Junction Box, as shown in the next figure. Insert
terminals crimped to suitable wires. For the exact
connector location
Refer to: 4.14 Special Conversions (page 131).
(Adding Connectors, Terminals and Wiring)
In order to avoid electrical issues due to leakage,
and to ensure connector compatibility, a
