The M-Button does convert the handle bar switch inputs from analog to digital. Then, from the the M-B to M-Unit a single wire (green coincidentally) runs back to the CONFIG input. This carries all control signal inputs.
The actual device power comes from the right side, as an output. It's all switched, fused supply essentially. Just run wires from the Turn L forward and rear to the signal indicator and you're turn signals are wired. (as an example).
As for the indicator programming, I'm only aware of time-based self canceling options. On the 10" interval, beginning with 10" from activation, up to 50" if I recall. You can also set them to be always on as markers, plus the flash mode when turning. Switch action resets the counter and begins again should you be turning left in LA...
The BRAKE function does allow "strobing" as long as the brake switch is active. I use this with an LED tailight, very bright.
Sorry ADV for the thread jack-
