ive got a 1999 f350 turbo diesel with an electrical problem I hope someone else has had; the interiopr lights and the outside light in the bed both come on while the brakes are being applied, and also when the motor is off and the truck is parked. Im worried about it killing my battery and leaving me calling auto club. Id appreciate any feed back from anyone who has had or who knows anything about this problem. thanks

 

Did someone just hook up a brake controller for a trailer? If so, sounds like they got some wires mixed up.
