V40 L4-1.9L Turbo VIN 27 B4204T4 (2003)
Combined these give a component designation, for example, 3/2.
There is a list of components at Component I.D List, where, with the help of the component designation, you can read off the name of the component, for
example, 3/2 = light switch. Diagram Legend: See: Diagrams/Diagram Information and Instructions/Diagram Legend

B. Junction points
The wiring diagrams contain numbered junction points, e.g. 43/352.
This information contains a section with a list of junction points. This list shows all the components which are connected to each junction point. See:
Power and Ground Distribution/Branching Point/Diagrams/Electrical Diagrams
The location of the junction points is shown in the "Cable harness routing in vehicle". See: Locations/Harness Locations
C. Connectors
Connectors provide a bridge between two cables harnesses and are described in the "Connectors". See: Diagrams/Connector Views
D: Electrical distribution
Operation of the fuses and relays is shown in the "Electrical distribution". See: Power and Ground Distribution/Diagrams/Electrical Diagrams
E. Data communication
Today's cars are equipped with a CAN network, which transmits information. Connections to this network are shown in their entirety on the respective
wiring diagrams. Complete information on CAN communication is can be found in "Data communication". See: Powertrain Management/Computers
and Control Systems/Information Bus
F. Abbreviations
A number of different abbreviations are used in the diagrams. These are explained in the "Wire Color Code Identification and Other Abbreviations".
