How to use the wiring diagram
The descriptions below apply in general to
all wiring diagram manuals, although not
all sections are necessarily contained in
this manual.
A. Component designation
Every component has a component designation that
consists of two parts.
The first part is a type number that describes the type
of component in question, for example 3/xx.
The second part of the designation is a serial number,
for example x/2.
Combined these give a component designation,
for example, 3/2.
At the end of the manual is a list of components, where,
with the help of the component designation, you can
read off the name of the component, for example
3/2 = Light switch.
List of type numbers
This list shows the type of component to which each
type numbers refers, for example, 3/x = switch,
=
6/x electric motor, etc.

B. Junction points
The wiring diagrams contain numbered junction points,
e.g. 53/352.
This manual contains a section with a list of junction
points. This list shows all the components which are
connected to each junction point.
The location of the junction points is shown in the
"Cable harness routing in vehicle" section.
C. Connectors
Connectors provide a bridge between two cable har-
nesses and are described in the "Connectors" section.
D. Electrical distribution
Operation of fuses and relays is shown in the "Electri-
cal distribution" section.
E. Data communication
Today's cars contain a CAN network, which transfers
information. The connections to this network are not
shown in their entirety on each wiring diagram. Com-
plete information about CAN communications can be
found in the section "Data communication". .
F. Abbreviations
A number of different abbreviations are used in the
manual. These are explained in the section "Abbrevia-
tions".
G. Component location
There is a section at the end of the manual in which the
appearance and location of components is described
in numerical order.
