Sundowner horse trailer wiring diagram

For many horse owners, the task of wiring their horse trailer can seem daunting. With so many wires, connectors and parts to consider, it can be difficult to know where to start. The good news is that understanding the wiring diagram of your horse trailer is much easier than you might think. In this article, we’ll provide an overview of the different components of a wiring diagram and how they work together.

Components of a Horse Trailer Wiring Diagram

A wiring diagram for a horse trailer is essentially made up of two main components: the power source and the lights. The power source is typically either a battery or the trailer’s electrical system. The lights are then connected to the power source via the wiring. Depending on the type of trailer, there may also be other components such as a brake light and turn signals.

Power Source

The power source for a horse trailer is typically a 12-volt battery. This battery is connected to the trailer’s electrical system, which provides power to the lights. The battery is typically located in a compartment on the back of the trailer, or you may also find a battery box mounted on the frame. It’s important to make sure the battery is properly charged and that all connections are secure.


Once the power source has been established, the next step is to connect the lights to the power source. This typically involves running wires from the battery to each light and connecting them to the appropriate terminals. Depending on the type of trailer, the lights may also need to be connected to a switch or relay. This will ensure that the lights are only turned on when they are needed.


Understanding the wiring diagram of your horse trailer can be a daunting task. However, by taking the time to familiarize yourself with the components of the diagram and how they work together, you can be sure that your trailer is wired properly and safely. With a little bit of knowledge and patience, you can be sure that your horse trailer is in safe working order.
