As title says 1996 topkick 7500 brake switch is good. It will leave the brake lights on even with the switch disconnected. both wires orange and white are hot as long as the breaker is plugged in. Disconnected plug under cab going back to lights. Still hot all the time. I believe the white wire is supposed to be cold unless brake pedal is pressed. Both wires still hot with turn signal connector disconnected. I do not have a wiring diagram (wish I did) My though right now is to cut the white wire at the brake switch and the turn signal connector and wire the brake switch direct to the turn signal connector. My only concern is what else It might effect. Any thoughs or ideas.
