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, 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, for
List of type numbers

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.
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.
