2019 850 GS Brake light wire

So BMW stepped back to have two wires - one for the brake light and one for the tail light?

My '17 F700GS has only one wire for both. The other wire is for the license plate light.

F850 wiring diagram

What color is the brake light wire on this bike?

Thanks in advance....

I just saw your message... did anyone come up with a wiring diagrams for F850GS? Did you discover if you bike had one wire for Brake light and same wire for running? (My F800GSA had only one wire for both). I found the brake wire today and tapped into it... but is shows either 12 V when brake is on or 2volts otherwise. which is not enough to drive my LEDs for running light. What did you find out/discover? BTW I have the F800GS wiring diagrams (2) if you want them. Roger T
