XC90 L5-2.5L Turbo VIN 59 B5254T2 (2004)

Combined these give a component designation, for example, 3/2.
At the end there 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. See: Diagrams/Diagram Information and Instructions/Diagram Legend
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, e.g. 53/352.
This information contains a section with a list of junction points. This list shows all the components which are connected to each junction point.
The location of the junction points is shown in the "Cable harness routing in the vehicle". See: Locations/Harness Locations
C. Connectors
Connectors provide a bridge between two cables harnesses and are described in the "Connector Views". 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 can be found in "Data communication".
F. Abbreviations
A number of different abbreviations are used in the diagrams. These are explained in "Wire Color Code Identification Identification and Other
Abbreviations". See: Diagrams/Diagram Information and Instructions/Wire Color Code Identification and Other Abbreviations
