These guys are probably right about the LED tail lights. I'll add that the GM PCMs are not quite as picky about low resistance and don't have to have the resistor packs.

Stop at your local Radio Shack and pick up a pack of 1K ohm 1/2 watt resistors. There will be 5 of them in the pack, but you just need 1. I find it easiest to place it at the tail light but you can place it near the brake switch if you prefer. It just needs to be connected from the ground wire to the brake signal wire. The resistor is not polarized, so which lead is which doesn't matter. The 1K ohm resistor won't even pull 1/4 watt, so it'll be cool to the touch unlike a spare bulb or resistor pack.
