Technically on an '04 you'll need both. Pin 33 (purple wire) on the C1 connector (blue one) will need 12v when the pedal is not depressed, and pin 6 (light blue wire) on the TAC module plug needs 12v when the pedal is depressed. Your truck should already have the right brake pedal switch with the two sets of connections on it unless it didn't have factory cruise control, which I would think would be odd on a fairly loaded suburban.
