2. MARKING OF ELECTRICAL WIRING
INTRODUCTION
This standard sets out specifications for the
uniform use of markings on electrical wiring.
The marking system consists of a numerical
system and a colour coding system, which
ensure a clear wiring layout and prevents faulty
connections and manufacturing errors.
The marking system does not apply to vehicles
subject to special conditions, such as military
vehicles.
Numerical and colour coding
Each numerical code consists of four digits, the
first of which refers to the main group and to the
colour.
Main groups
Power supply (red)
1000 to 1099
Voltage generation
1100 to 1199
Power supplies before
ignition
1200 to 1499
Power supplies after
ignition
Lighting (yellow)
2000 to 2099
Direction indicator lights
and alarm light
2100 to 2599
Vehicle external lights
2600 to 2999
Vehicle interior lighting
Warning and inspection functions (blue)
3000 to 3399
Engine functions
3400 to 3999
Vehicle functions
Consumers (black)

Starting, stopping, engine,
glow functions
4500 to 5499
Vehicle functions
5500 to 5999
Automatic transmission
Special applications (colour as desired)
6000 to 6999
Earth connections (white)

Notes:
-
The “M” with serial number coding on earth
wiring is used for production-related
reasons.
-
In the case of straight splicing of the wiring
(cascading), the numerical codes are shown
on each separate wire followed by a serial
letter.
Earth connections
The application of electronic systems has made
it necessary to divide the earth connections into
groups. There is a distinction to be made
between two different types of earth connection:
-
switching earth
-
test and signal earth.
The switching earth is the conventional type of
earth.
The test and signal earth is used exclusively for
electronic systems.
The wiring colour for both types of earth is white,
but the test and signal earth wiring is marked
with numerical codes (from 9000 to 9500).
NEVER USE THE TEST AND SIGNAL
EARTH WHEN FITTING AN
ELECTRICAL COMPONENT
If you do this, electronic components may not
work correctly.
If an electronic component needs to be
connected, the earth for this system must be
connected to the central earth connection in the
cab.
The connection point is located in the dashboard
connector lead-through.

1.
“1000” and “1010” is shown at the top left of
the diagram.
These stand for:
1000 = supply before ignition.
1010 = supply after ignition.
2.
“M” is shown at the bottom left of the
diagram.
This stands for:
M = earth connection.

3.
To make it easier to find your way around
the circuit diagram, a “search bar” is
included at the bottom, which contains
numbers.
These numbers are called location
numbers.
In the legend to the circuit diagram, the
description of the basic code (ECN) is
followed by the relevant location number.
This means that a specific component can
immediately be located in the diagram.
4.
There is an arrow above location numbers
60, 63, 64, and 68 in the diagram example.
Below this arrow is a number. This number
refers to the location number on the search
bar where you can find the relevant wire
number.
5.
Beneath the “M” (earth connection) line are
found the “NC” codes relating to relay
G154, the “CO” codes relating to relay
G107, and “NO” codes relating to relay
G000.
These codes stand for:
NC = normally closed (= break contact)
CO = change over (= changeover contact)
NO = normally open (= make contact)
These contacts can be found at the location
numbers shown beneath the codes “NC”,
“CO” and “NO”.
At the relay contacts shown in the diagram,
you will also find the location numbers
indicating the relay coil locations.
6.
In the circuit diagram, you will find the basic
codes (for example, E002). What these
codes stand for can be found in the legend
to the relevant circuit diagram.
