Google up "DIN electrical codes". Those numbers are universal on all German vehicles. All the relays and switches will have them if they are DIN spec. Makes electrical diagnostics easy squeezy once you get familiar with the code.
Any wiring diagram for a German vehicle that does not show those circuit numbers is totally lacking of any basic German design and process understanding.
