Where is the brake light switch on a 1995 Chevrolet Silverado 4wd?

UNDER the dash, on the steering column and it makes contact with the brake pedal It looks like a bracket, that wraps around the brake pedal arm, and it has a cylinder type switch that makes contact with the brake pedal arm. When the brake pedal is pressed down it pushes the cylinder switch together which closes the circuit and makes you brake lights come on. It may be a fuse or wires but start with the switch.
