36120 Wiring help

The 36120 car controller that's going in my Savage has 6 wires going to the motor and 4 going to the battery. I was wondering if the 6 wires just paired up with each other and if I could just solder them together so that there would only be 3 wires. I was also wondering whether I could do the same thing with the battery wires. Is it possible to just cut off the second set of wires so there is less mess?
Thanks
