i have a 4 x 8 trailer that i am wiring for lights. with my truck lights on, the running lights, turn signals, and flashers work fine but when i press the brake pedal the lights on my trailer go out. if my truck lights are not on the brake lights on my trailer work. why is this happening? any help or ideas is greatly appreciated. thanks.
