FUTURE Foundation Design Challenge Wires

For the FUTURE Foundation Design Challenge, is it legal to use non-Vex wires? Or if not, is it legal to modify Vex PWM wires?

I’m not sure what you mean by “wires.” If they are necessary to power non-VEX decorative items, or as a decorative element themselves, they would be legal. Perhaps you could explain in more detail?

Would it be legal to make a male to male PWM wire to plug into two different cortexs to make them operate together?

Yes, that would be OK.
