4.14.2 Engine Run Signal (D+ Alternative)
Give Away Engine-run Signal Connector (Passenger side)
WARNING: Do not cut into the
alternator wires or use the alternator
as a source to obtain a 'D+ Signal'
The Engine Run Signal will only support the basic
vehicle system.
Vehicles built from August 2006 will have a
suitable ‘give-away’ connector (6.3mm flat blade
receptacle) in the main vehicle harness. This is
located on the passenger side and can be
accessed by dropping the glove box.
Most early-build vehicles do not have this
connector. In such instances, for engine run (C4-7
on the central Junction Box), there is a dedicated
terminal (pin 16) on the passenger-door loom /
main loom in-line connector available to energize
a relay (maximum one (1) relay). A T-piece
harness (6C1V-14A411-F*) is available from your
Local Ford Dealer to fit between the door / main
loom in-line connector. If the vehicle does not
have this fitted as a factory-fitted option
(campers, for example, do have this pre-fitted),
one way to install this is:
•Remove the passenger side mirror on the
using a long-reach M8 socket (note: right hand
drive vehicles use shear bolts that will need to
be replaced)
•Pull out the flexible grommet between the
body and the door, including the connector
shroud behind it.
•The connector between the main vehicle
harness (14401) and the door jumper harness
(14A631) Can now be pulled through and
disconnected
•The T-piece jumper harness can be inserted
between the two connectors and pushed
back into the body.
•Drop the glove box fully by depressing the side
detents – the single lead with connector
(6.3mm male terminal) can be pulled through
a square hole in the body-side inner panel,
behind the flexible grommet
•Re-fitment of the flexible grommet and door
mirror is the reverse of the above process,
noting that new shear bolts will be necessary
for right hand drive vehicle, part number
W712939-S422.
This engine run signal is ground switching (max.
current sink 200mA), for example it provides no
positive output and is only active under the
following conditions:
•Ignition on
•Engine running at normal idle
•Alternator giving output
•System voltage about 9 volts
FordTransit 2006.5 (April 2006–)

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)

4.14.3 Connectors
Cutting into the Original Wiring
System
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.

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:
FordTransit 2006.5 (April 2006–)

4 Electrical
134E79034

•10mm from static components (unless
clamped to it).
•250mm from exhaust system.
•30mm from rotating or moving components.
Wires / looms passing through sheet metal must
be through protective grommets that also ensure
a watertight seal. Adhesive or tape is not
acceptable.
CAUTION: Do not feed additional
wires through existing ‘occupied’
grommets.
A number of locations in the dash panel have
been identified for additional holes to route wires
through. See figures E74496 Left Hand and
E74497 Right Hand Drive Dash Panels for
locations. The selection of suitable locations will
depend on the vehicle specification – please
check that the immediate surrounding area is
free from obstructions and/or components to
prevent damage to critical systems, and that the
grommet will seal properly.
Typically two sizes of hole are recommended:
•Grommet to suit with hole size 40mm
diameter for dash panel – bunched loom.
•Grommet to suit with hole size 30mm
diameter for dash panel – up to three (3)
wires.

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.

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.
