Functionality of Each Wire
Each wire in the 7 pin horse trailer wiring diagram serves a specific function:
White Wire
The white wire is the ground wire, which connects the trailer to the towing vehicle’s frame. It ensures a safe and reliable electrical connection between the two vehicles.
Brown Wire
The brown wire powers the tail lights of the trailer. It is usually connected to the vehicle’s parking lights, which allow the trailer to be seen from the rear at night or in low-light conditions.

The yellow wire powers the left-turn and brake lights of the trailer. When the vehicle’s left turn signal or brake pedal is activated, the current is sent through the yellow wire, lighting up the corresponding lights on the trailer.
Blue Wire
The blue wire powers the electric brakes of the trailer. When the vehicle’s brakes are applied, the current is sent through the blue wire, activating the trailer’s electric brakes.
Black Wire
The black wire charges the trailer’s battery while it is being towed.
Red Wire
The red wire provides auxiliary power to the trailer, which is used for powering accessories such as interior lighting or a refrigerator.
