Hi Josh,

Good to see my idea validated by Roman :)

The reason I split the current limiting resistors for the LED was to provide
some protection to the PIC for Electro-Static discharge and short circuits
in the cable. To fulfil these requirement, they MUST be located at the PIC.
And for ease of assembly, the other resistors should be there as well I'd
assume. I don't think you'll get any benefit moving them to the end of the
cable.

Roman, this is the circuit I posted:
