The heading says it all. Solder according to the schematic and program the Arduino using attached program (adjust as needed, defaults work well for me). Should work instantly.
You can put the Arduino Nano inside the controller case (insulate using shrinking plastic), in that case connect the power to +5 pin, ground to GND pin, output to ZB pin.
If you put it outside the case, connect output to throttle input, power to throttle power and ground to throttle ground. Before reassembling, remove all power sources and short-circuit the big capacitors or you could blow the board as you insert it in the conductive housing.
PAS output can be connected directly to D2, Arduino has an in-built pull-up.
