That's a nice gadget, what other output did you use it for besides the horn?
1. Heated Seat (Yes, Arizona and heated Seat...

)
2. GPS (Garmin)
3. Additional High Beam (only place where I had an additional relay)
4. Tank Bag (SW Motech, has a Power Socket inside, Quick Connect)
5. Power Commander
The previous owner tapped for the Power Commander Power Supply the wire to the Running Lights. So it is described in the manual. BUT he did not consider the Running Lights / Brake Light is only one wire, PWM signal and drops to about 4 Volts when no Brake signal applied.

I developed a Brakelight Flasher for the PWM Signal (Arduino based), so was using the 12V here as well
6. Extra Power Connector in case I was using the mobile in a mount, Batter Tender Connector
I had it with relays etc in the past ... was sort of pain in the ass
Battery is at the top of the Bike, close to the tank, Power Commander and PDM under the Passengers Seat, so I had to route the wires a bit across the bike, but I had an additional fuse in the wire to the PDM.
Unfortunaly I did not document what I did, so I knew about it, but when I decided to sell the BMW (which did not happen yet), instead of explaining to the new owner, I reverted everything back to stock.
