Actually it is a lot simpler than that, I already bought a Driver Board and all it does is control the Led, all you have is 8 connections: Battery(+,-), Switch (In,Out) momentery, Crash/Lock; either hook up a Momentary Switch, Shock Sensor or Both, Led Out(+,-).
Now all the Sound Functions and the speaker are part of the other board, I took apart a Yoda(Hasbro) Saber and it looks like all you need is to tap in to the Switch from the Driver and supply battery power, it already has the Speaker and Shock Sensor built in. I hope this helps.

May the Force
Be with You
