The descriptions below apply in general
to all wiring diagram manuals, although
not all sections are necessarily contained
in this manual.
How to use the wiring diagrams 1:2
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, e.g. 3/xx.
The second part of the designation is a serial
number, e.g. x/2.
Together, this constitutes a component designation,
e.g. 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, e.g.,
3/2 = light switch.
List of type numbers
The list shows which type of component that
respective type numbers refer to, e.g.,
3/x = switch, 6/x = electric motor, etc.

B. Branching points
The wiring diagrams contain numbered junction
points, e.g. 53/352.
This manual contains a section with a list of
branching points. This list shows all the components
that are connected to each branching point.
The location of the branching points is shown in the
"Cable harness routing in vehicle" section.
C. Connectors
Connectors provide a bridge between two cable
harnesses and are described in the "Connectors"
section.
D. Electrical distribution
Operation of the fuses and relays is shown in the
"Electrical distribution" section.
E. Data communication
Today’s cars are equipped with CAN, LIN & MOST
networks that transmit information. Connections to
these networks are shown in their entirety on the
respective wiring diagram. Complete information on
Data communication can be found in the section
entitled "Control modules".
F. Abbreviations
A number of different abbreviations are used in the
manual. These are explained in the section
"Abbreviations".
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.
