There are two wires for +5V and GND. The other two are Channel A and Channel B. These all get wired to the Digital Input/Output pins on the Digital Side Car. Unfortunately, since there are two channels, you must wire each channel to it's own set of pins. That leaves you with a little bit of a conundrum. What you have to do is connect the +5V, GND, and Channel A to one Digital I/O channel. Then wire Channel B to just the signal pin of another channel.

You can achieve this by cutting 2 PWM cables in half, and soldering the +5V and GND to the red and black wires of one of the PWM cables on the socket side (so you can plug it into the DSC). Channel A should be soldered to the white wire in that PWM cable. Channel B should be soldered to the white wire in the second PWM cable, and clip the red and black wires and insulate them with heatshrink or electrical tape.

Good luck!
