K75 HORN - LOCATION AND HOW TO MOUNT

I would like to know where is the location of the naked K75 horn(s) and how I supposed to mount them on the bike. I see in some photos a single black painted horn in front of the engine and just under the plastic cover of the radiator. Is this the original position? Do they come as a couple or as a single horn? Do they come painted in black?

Thank you for your patience,

Goldetie,
The horn is situated behind the headlamp surround. On the naked K100 they come in tuned pairs but the K75 are crappy single squeeks.
To let people know I am about I fitted these loud Klaxons (e-bay just type klaxons in search) They certainly hear you.
