2018 1200RT Police

Got any questions about the BMW's R1200RT/R1250RT's onboard audio, Bluetooth or the Electrical system?

2018 1200RT Police

Post by RTP »

Hi, I've searched the term "horn", but found nothing similar to my problem.
I've just bought an ex police 2018 1200RT. The bike does not have a horn fitted. I've removed the side panels but can't find the original horn plug on the loom. Does anybody know where the original horn wiring should "emerge" from the harness - it may be taped up/hidden somewhere, or it may have been cut off when the sirens etc were removed?
Failing that, does anybody know where to download/purchase an electrical drawing for the bike so I could maybe tap into the horn cables coming from wherever they are fed from?
I guess my other options are to fit a new switch and wire a horn in from scratch (last resort), or buy an ezecan and hope the original horn switch is still "seen" on the canbus.

Any advice would be very much appreciated.

Cheers,
Tony.

Thanks for the quick reply. I've looked up and down around the fork area - couldn't see a plug unfortunately. If I knew where about the horn cable exited the main harness I'd have a place to start (unless it should exit right near the forks, then it'd probably be a tank off job.

Post your location, maybe easier if you can have a nose at another bike to give you an idea of the horn setup.

You only need this on ya bars

Thanks for your help everyone. I've had a diagnostic tool on it today and the horn switch is still being seen on the canbus, so ezcan it is.
Cheers.
