6V Bosch fog light relay VW Porsche NOS

Vintage VW and Porsche 6V Bosch fog light relay in new old stock (nos) condition. The relay comes with relay mount bracket, cable and nice old Bosch box. The set was made by Bosch in Germany in the 60ies. The screw terminal relay has the following four connectors: 85, 86, 87, 30/51. If you want to wire the fog lights like in Germany, then they burn only with the headlights and a short wire instruction without warranty will be like this: 85 blue to fuse box high beam / 86 yellow to fog light switch / 87 white to fog lights / 30/51 red to 30 ignition switch. I do not know if the cables have the correct length for your vintage VW or Porsche. The scans show how to mount the relay and how to wire in a VW Beetle. Both scans are not included.
