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, for example 3/xx.
The second part of the designation is a serial number, for examp le 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
The list shows which type of component that respective type numbers refer to, for example, 3/x = switch,
6/x = electric motor, etc.

B. Junction points
The wiring diagrams contain numbered junction
points, for example 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 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 & MOST networks that transmit information. Connections to
these networks are shown in their entirety on the
respective wiring diagram. Complete information on
CAN & MOST 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 "Abbr eviations".
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.
