I am installing an Stebel Nautilis mini to make the bike more noticeable to oblivious cagers. I bought an accessory wiring harness to help with the install.
The wiring harness directs me to wire ground to a bolt on the bike. Does the F800GS support getting to ground via a bolt to the frame or should I be running it back to the battery? I'm not sure how canbus handles the frame and ground.
Also, if I want to pull power from the existing horn using a positap, which wire triggers the relay? I think I read somewhere that brown is negative (which would answer the question). Also, is it better to connect the new horn wiring back to the original horn connector? Ultimately, that's better for returning the bike to stock form, but I would need to buy the connector. Is this something that the BMW dealer would sell?
For the mounting, I fastened the horn via a bracket to the radiator housing using an L bracket, with the top of the compressor stabilized with JB Weld. Any thoughts on if this will eventually cause the plastic housing to fatigue and fail? I only thought of this after the install. I noticed that others have mounted the compressor to the composite bracket that supports the light pod and instruments. My concern with that location is that there are several wiring harnesses that run through the bottom of that bracket and I was concerned about vibration eventually rubbing through the wire.

Finally, does anyone have feedback on the reliability of the horn after 2-3 years? I noticed that much of the original install information is from 2-3 years ago. At that time, it seems the most experience was limited to 7 months.
All help is appreciated.
