I emailed Yamiya and asked about the indicator light mechanism. Their reply was to ask if I was looking for the harness pictured below. So I'm guessing the Japanese speedo harness has the extra light bulb on it? I can't tell by the picture. But that's not the mechanism itself, so I stopped by my local Honda dealer and asked the lady in the parts department if they could order Japanese domestic parts. The reply I got was crickets....and a blank stare...and "Um...I don't think so." I have a cousin who teaches Japanese and spent some time there so I'm going to ask her to help me search the web for the remaining pieces to our puzzle. I'll post any finds.
