I own a 1987 dodge d150 and I don't have any brake lights, I have turn signals and park lights. I tested the switch at the brake pedal and am not getting any power but I cannot locate the fuse or where the wiring goes after leaving the brake pedal.

The wiring in a brake system is that on properly working brakes, the wiring to the lights completes a circuit lighting the brake lights up when you press the brake pedal in... I'm not sure where the wiring is but it is somewhere attatched to the brake pedal
