Well a guy I worked with had E-brakes on half the axles on his short end-dump. LEO, doing a "safety inspection" thought he was checking for water in a air tank, pulled a cable. The driver standing next to trailer saw the smoke. When they weighed the trailer, it was overweight because the brakes did not work on 2 of the axles. I did not have a trailer behind my old F500, so I pulled my controller, so he could get down the road.
Like somebody else said, the instructions warn against pulling pin while the cord is attached.
