Hey guys so we are getting our 1980 coach ready for our trip to the smokies Monday and I noticed no brake lights so I checked fuses some seemed nasty and old so I swapped them, no lights, I then checked the hazards switch, all works, now I’m looking for the brake switch and there is nothing that looks like a brake switch near the brake pedal, i then take the brake lights out, 0 volts when no brake applied, 0 volts when brake is applied, headlights turn on and marker lights on 6 volts, brake apply with all lights on 6 volts. What am I missing please help before we have to cancel our trip. Any advice where the brake switch.
