You can have the switch pull the appropriate pin to ground (as the manual shows) and then have the PROGRAM turn the appropriate LED on to match the switch (Pwm1_red, for example).

This is what we do.

You can even use the program to have the lights give more information than just "on" or "off" for instance you may want to indicate an error condition by flashing the LED.

The code is not that hard to write and you don't need to have auxilary power supplies on your OI.

Just a suggestion.
