Opel utility headlight switch issue

[Mtape]

Hallo guys my Opel Opel utility headlight switch is failing to bring high beam on, does anyone have the wiring diagram.

Nothing could have damaged the wiring unless someone was fiddling, check the fuses, sometimes high beams have their separate fuse.

I've checked the fuses, relays, they're all fine. I've even triggered the high beam relay and the light comes on, using a hot wire to ground. What I'm looking for is the wiring schematic for the connection, that plugs to the headlight/ indicator switch.
Thank you
