Also one thing I've learned being head electrical on my team is simply don't try if you don't know...
Electrical isn't like programming where you can hit backspace, in electrical things can burn, arc weld, explode, and kill you.
Also I recommend tinning wires to newbs, helps them understand the wires a lot more.

None of the FRC legal motor controls of the recent past have used the 5v signal wire in the PWM cable.
The way the motor controllers that I have looked at their schematics work is that the black and white wires are connected to an optoisolator. So all the signal does is light up an LED.
