Not familiar with this unit.
This thread discusses the wiring and other considerations.
You can tap into the CAN signals from the rear alarm connector. Then you can get the throttle position from the connector on the left side mentioned in the referenced thread. You can't use the CAN signal for throttle position as it only shows the actual opening of the throttle plate, not what you are commanding at the throttle grip.
Braking could get interesting. I think the rear brake light is connected to the CAN. Haven't figured out which signal is for the brake light...yet.
