MXP board design help

My thinking was that the 5V of power would go into the power line on the PWM cable, then in the component (talon, victor, spike, ect) that the PWM cable plugs into the power would then connect to the PWM ground. Back on the MXP board before reaching the digital ground the the PWM cable would power an LED. That way your LED would only light up if the Cable was plugged in at both locations.

I don't understand how this is supposed to work. Can you post a schematic that shows the connections, especially the part that provides the LED current?
