Look for the power button and the cable already soldered from this kit: http://www.diyeboard.com/v11-single-belt-motor-sine-wave-foc-esc-speed-controller-p-523.html
I messed something up on mine and it isn’t working right anymore so I’m stuck pushing-to-start and waiting for auto-turn-off. I don’t have a soldering kit otherwise Id try to fix it myself.
