1989 Polo fox 86C wiring (horn)

[sztabo85]

greetings,
In search of wiring diagram/schematic for above vehicle.
Horn triggers while driving, also when shifting to Reverse(???)

Steering center horn button removed/disconnected.

any ideas where the wiring harness (for Reverse switch on transmission) comes close to Horn wiring?

thanks in advance,
John
