The configuration of the Auxiliary Fuse Box is
hard wired (as shown in Figure E75088) Auxiliary
devices should be connected via the 16-way
connector C1. Most fuse / relay configurations
are available to meet particular requirements.
A maximum of 60 A is permitted per power feed,
with maximum individual fused circuits of up to
20 A.
There are 10 possible fuse locations in the fuse
box. Please refer to the following table (Fuse
Location), which shows how the fuses are
divided between the two power feeds.

The Special Vehicle Option Auxiliary Fuse Box,
with integrated link harness, will provide the
following connections:
•– Ground
•– Battery +
•– Ignition
•– Engine run
•– Switched interior illumination
The fuse box is connected to the vehicle main
battery(s) but when the deep cycle battery is
installed it is always connected to the deep cycle
battery.
4.13.5 Additional Ignition,
Instrument Panel Illumination and
Air Conditioning On Signals
Access to these feeds can be obtained via a
jumper harness (6C1V-14A411-*) that fits into the
8-pin in-line connector between the instrument
panel (14K024) and heater (18B518) harnesses
located behind the glove-box. This jumper will
provide the following signals through three, single
6.3mm colour-coded connectors, please refer
to Fig. E75089 Heater jumper for illumination,
ignition and air conditioning on access.

8 Pin Connector - for Ignition, Instrument Panel Illumination and Air Conditioning
On Signals

KL15 (12V ignition feed)Pin 4
Used instead of Pin 4 on vehicles euipped with Air Conditioning)Pin 7
Instrument Panel Illumination (12V feed)Pin 6
Air Conditioning On (12V)*Pin 5
It is recommended that these signals are used
to energize relays, or any other device, as long
as the maximum current does not exceed
300mA per function, or 600mA (suitable for
powering two relays) for the ignition feed.
NOTE: *There is NO direct provision for an air
conditioning on signal. When the air-conditioning
is switched on, 12V is applied to the defrost
compressor switch and the Air conditioning low
speed blower relay (both integral to the heating
ventilation and air conditioning unit and 18B518
wiring), and the Air conditioning cycling switch
(in the engine bay as part of the 9K499 wiring
[via the 14401 and 14K024 harnesses]). Additional
load on this line is limited, so air conditioning on
is only available as a signal (300mA) for voltage
sensing or powering of a relay – powering
another device directly is Not recommended.
Where additional current is required from either
output, a standard relay should be used, please
refer to Relay Figures E75017-E75021.
The Special Vehicle Option Auxiliary Fuse Box is
recommended as the most suitable power
source for these relays. Please consult your local
National Sales Company representative for
availability.

4.13.6 Relays and Switches
Relays
Single pole relays must be used under the
conditions:
•Single pole, 2-way (change over) is used to
switch from one circuit to another please refer
to Relay Figures E75017-E75021 for typical
relay circuit diagrams.
•Relays can be installed inside the vehicle or
inside the Special Vehicle Option Auxiliary Fuse
Box.
•The Ford standard relays have a nominal
current of 300mA (max) at 25°C. Relays with
greater loads should not be used.
•For maximum switching currents please refer
to Relay Figures E75017-E75021.

In addition to the fuses and relays fitted to the
Pre Fuse Box (PFB), Engine Junction Box (EJB)
and Central Junction Box (CJB), depending on
vehicle options, there may be up to 3 relays
mounted directly to the Heating, Ventilation and
Air-conditioning (HVAC) unit. These relays should
not be tampered with as they affect operation
of the associated system.
Heating, Ventilation and Air-conditioning (HVAC)
1 x 82GG-13A025-CAAir-conditioning
2 x 82GG-13A025-CAFuel-fired Heater without Air-conditioning
3 x 82GG-13A025-CAFuel-fired Heater with Air-conditioning*
*In addition to the relays, there is a diode 91AG-10374-B_
These relays have a different terminal
arrangement to those fitted throughout the rest
of the vehicle – if they need to be replaced, only
components with the same Ford part number
should be used.
Switches and their Illumination
The main instrument panel switches work in
conjunction with the Central Junction Box, and
are momentary action (non-latching) types. The
Central Junction Box is responsible for control
operation of the respective systems.
For any additional functions, unless the
interfacing module accommodates momentary
action switches, it is recommended that latching
types are used.
Three switches are available:

Rotary light (beacon)6C1V-13D768-A_
Rear work lamp6C1V-13D756-A_
Water faucet (heater)6C1V-19H218-A_
Search illumination for added switches can be
taken from any of the existing switches, by
connecting to the appropriate feed wire.

4.13.7 Windscreen wipers
NOTE: Power to wiper motors is limited by the
size of the wiring and associated relays. If any
alternative wiper installation is made, it must have
a specification equivalent to Ford components.
Refer to: 5.6 Glass, Frames and Mechanisms
(page 211).
The base wiper system should not be tampered
with (controlled by Central Junction Box and
multiplex architecture).
Headlamp wash – such installations would need
to be controlled via an external timer relay. The
Special Vehicle Option Auxiliary Fuse Box should
be utilized.
Heated washer jets – aftermarket systems should
be fitted via an ignition feed, via an additional relay.
The Special Vehicle Option Auxiliary Fuse Box
should be utilized.

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.
