Nope, no resistor needed. I actually also found out that even with the older design, a .01uf cap works as well and doesn't present a constant load. The resistor was to force the triac to fire if it didn't have a resistive load, turns out the cap does the job as well. The current version of the Super-Chuffer board has the .01uf cap on-board.

I recommend using a 470 ohm resistor in series with the LED and connecting the positive side to track power. The cab lighting output already has a diode in front of the FET switch, so all you need is the resistor in series with the LED and you're set.
