Recently I have started working on a custom MXP breakboard, its main design purpose is a place to mount a I2C driven IMU unite sourced from either Adafruit or Sparkfun. I feel fairly confident there, where I am running into problem is with LED based continuity signal lights I want to include to show if PWM cables are plugged in.

Long story:
The problem is the rules with the MXP boards, specifically the part about being active vs passive. To have the LEDs light up, my plan had been to run the 5V power across all the power lines for the PWM terminals. Then on the PWM ground each cabled connected to the board would have an individual path to an LED that would then connect to the shared digital ground. 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.

Short story (or long story continued):
The rules (according to FRC 2015 game Manuel) do not allow active component in the PWM path way if it controls motors (it will). To my understanding LED are an active component because they are diodes.

So is there any other way that I could hook these LEDs up that would show continuity and still be considered a passive board?
