I looked up the 2010 Chevrolet Colorado and the two switches on your brake pedal is for the brake light and the other switch is for the traction control/cruise control. You will need to use a circuit tester, like part # PTW2993, and test the wires. I would start by looking for a light blue wire and test that wire for power only when the brakes are applied.

I am including a link to a FAQ page on brake controllers. It does list some colors of the wires on vehicles that are needed when installing a brake controller. Vehicle manufacturers do change wiring configurations regularly, that is why we always recommend using a circuit tester to verify all connections.
