Rieju ranger horn wiring?

[Bigboresrule]

Bought a 2021 300 ranger the switch on left handle bar shows a horn button along with turn signal switch. I believe behind head light I've found the turn signal wires but can't locate the horn wiring and have pulled the tank to see if the wires are there. I've found a pre ktm gas gas wiring diagram and see the horn and turn signal shown. The Rieju manual I got does not show any wiring nor mention horn wiring. Any one been down this road?
