Just recently, I mounted a new Stebel horn. Perhaps this posting might be interesting to you. Unfortunately, I have to write in English, my German skills are quite poor
A horn is used for your safety and therefore should impress those who “overlooked” you. As a result, I went for the Stebel Nautilus horn. For those who do not know this horn, it is a beast and makes a hell of a noise!
The Stebel Nautilus works on two different frequencies (530Hz en 680Hz), has a build-in compressor, measures 140mm x 112mm x 100mm and produces 139dB(A) at 10cm and 115dB(A) at 2 meter distance.
Stebel Nautilus, 2-tone horn To build-in a Stebel Nautilus on a K1300S is a small challenge as there is not much room. I made a bracket from alluminium (black powder coated) that is connected to the front sub-frame at the right side. By doing so, the sound goes directly to the open part of the bike resulting in a maximum effect.
Bracket to mount the Stebel Nautilus As the Stebel Nautilus requires 18A, it is necessary to use a relay.

Stebel Nautilus mounted on my BMW K1300S I made a y-cable that is connected to the original horn using spare part connectors of BMW. By doing so, you do not have to cut the wires. Additionally, you will get a triple tone horn!
Horn connectors BMW Partnumber 0402342 en 0402344 As a result, the cable that controls the Stebel looks as follows.
