CONTRARY TO WHAT YOU'VE LIKELY READ, THE M-BUTTON IS NOT EASIER, FASTER, OR IN ANY WAY LESS COMPLICATED THAN RUNNING DIRECT WIRES FROM YOUR SWITCHES TO THE M-UNIT. THE M-BUTTON MUST BE INSTALLED INSIDE YOUR HANDLE BARS AND THIS IS NOT A SIMPLE TASK. If you are building a show bike where all of your wiring and cabling is run internally then this is a brilliant device for accomplishing this. The mo.Button (m-Button) is a CAN-BUS device that converts the switch inputs to digital signals and sends them over a single, thin cable to the mo.Unit.
