The brake stop lamp switch is located at the top of the brake pedal of your 2008 Chevy Express. You're looking for the cold side circuit wire that only shows voltage when the brake pedal is pressed. This should be a white wire, but I'd recommend using a circuit tester like # PTW2993 to confirm.

If you click the provided video link, and fast forward to the 20:15 mark, you can see where the stop lamp switch and the correct wire is located.
