E brake activates truck brake lights
Was bored today because I missed the Houston bomb party  and decided to get one of the "honey do's" done on wifeys truck.
Her Pac brake will slide you forward in the seat and vehicles behind you on our twisty, limited visibility, hill country roads need some warning that she fired the retro rockets.
It was really easy to do, I found the two wires on the brake controller, one +12V and the other goes from 0 to +12V to turn on the brake lights. Wired them to the normally open contacts of a relay. Took the relay coil wires between ground and the side of the throttle switch that goes through the firewall to the Pacbrake solenoid.
BAM! Ebrake on, brake lights on. Easy. Next to add a push-pull switch in the coil side of the relay so we dont trip the trailer brake controller.
