Hey Dude that set up looks pretty solid. You need a toggle switch with 6 prongs. The 2 center prongs are for the 2 wires from the battery. Then you split the wires from the the moter so you have 4 instead of 2. You simply connect the wires opposite on each side if the center battery prongs. The switch changes the polarity to run the motor forward or reverse. You will need a temporary on toggle switch unless you put limit switches in place. Temporary just means you would have to hold the toggle in either direction and it will always go to off in the middle. Did that all make sense. Let me know, I've wired many of these.
