Hi guys
just installed on my (2015)1200RT. Does anyone know where I can splice the yellow wire to for switched power? Currently the unit will only power up once I’ve started the bike, and pushed the silver button on the unit. I hoping this can be cured by splicing the yellow wire to a switched live. Just don’t know where such a wire is on the RT.
I tapped the yellow wire into the tail light wire, using a voltmeter to make sure you are selecting the one that powers on with ignition (driving lights) and NOT the one that only comes on with the brakes!
The easiest method is to use wire strippers to peel back a section of insulation on the tail light wire without breaking the copper itself, then wrap (ideally solder) the yellow to this and tape it up.
Edit: After seeing which bike you have, I believe BMW pulses the tail light to the lower level so the above method may not work for you. Perhaps do a search on a BMW forum to see how to get ignition power from their BUS system?
