3 wires will go to the motor you need to get deans for the enpty battery leads, there is one connector with 3 wires that goes to the receiver, if ur running a receivr pack you need to remove one of those wires(not shure of which one on the MM)and then there is the onoff switch
@Asianplayer: It looks like you have set the turn ration of your dremel too high and were cutting too hasty. I experienced this with PC Case modding, high turn ratios can make the dremel jump especially if you hold them with one hand (steel is really nasty!)
