use either 1 or 2 and 3 or 4 for power supply. the other ones (look at the documentation because i don't have it with me right now) are the outputs. the outputs can get hooked up to the digital in side of the rc, each of them a signal wire. You need to ground all of them though. out setup is in an L shape, with the base of the L the ground and one signal and the upright part 3 more signal wires. we just just pwm cables for this. it works well enough for testing purposes
