European wiring diagrams (DIN) differ both in layout and nomenclature from SAE wiring diagrams. DIN schematics are linear with power feeds shown on the top and ground (earth) at the bottom of the schematic.
Electrical components are placed between the two and any output path from that component is referenced to a location number which is listed at the bottom.
Component designation and relay outputs are explained in the following link: Understanding DIN Wiring diagrams
