Electrical system questions - turn signals '94 R1200R

Hello Folks, A friend of mine recently acquired a 1994 R1200R. He is attempting an electrical troubleshoot of the turn signal system which seem buggered up. The question I have is concerning ground/earth wiring. I myself have have a 2004 K1200LT and it has all the ground wires are brown tying to a common point, not the frame. Is the same true with this older R1200R bike? We have yet to purchase a service manual that would have wiring schematic.
 
Hi! I'm going to change the title of this thread so it's easier to tell what it's about!
 
BMW has used brown wires for ground since I was a Cub Scout. They all eventually tie to the chassis or the engine or the battery.

However, I don't think BMW built an R1200R in 1994. So we really don't know what the bike is.

Thanks Paul, I will need to confirm the model number again.

All German cars, too.

It's a standard developed by Bosch.

ground = earth, and brown is a pretty good representation. Kind of like low beam is yellow and high beam is white.
