Yup!! Yammy's color code is Yellow for brake, Blue for running lights, and Green or Brown for turn signals. Without going out to the garage to check, I think green is left but I'm not totally sure.
The clutch switch can be disassembled and serviced, there is a tech note somewhere done by Dingy. Also the clutch and brake switches are interchangeable if your bike has cruise. The wire colors are different but they plug in the same. That being said I might have a new one for you, I'll check later and get back to you...
