Does anyone know how to open the speedometer up? I am trying to install a LED light on the white face of the speedo that will be tied into my green blinker reminder on the tank so I will remember to turn them off during the day. I know I should just use the old left thumb press thing a million times to get used to it, but until i do I would like the added safety of seeing the little red LED light up on the face of my speedo. I've removed the speedo and the chrome housing but i dont know how to open it the rest of the way up and i dont want to break it.
