Electric trailer brakes are an essential component of a trailer’s braking system. They activate when the driver applies the brakes in the towing vehicle, helping to slow down and stop the trailer. To properly install electric trailer brakes, it is important to have a wiring diagram that outlines the necessary steps.
Understanding Electric Trailer Brakes
Electric trailer brakes are a type of braking system that uses an electric current to activate the trailer’s brakes. This current is sent from the towing vehicle to the trailer’s brakes through a wiring system. When the driver applies the brakes in the towing vehicle, the current is sent to the trailer’s brakes, causing them to activate and slow down the trailer. This ensures a safe and efficient stopping process.
Electric trailer brakes are typically found on larger trailers, such as those used for hauling boats, large equipment, or livestock. They are also commonly used on RVs and travel trailers.
Understanding how electric trailer brakes work is essential when it comes to installing or repairing them. A wiring diagram is an important tool for anyone looking to work on electric trailer brakes.
Electric Trailer Brakes Wiring Diagram
A wiring diagram is a visual representation of a trailer’s wiring system. This diagram outlines the various connections between the towing vehicle’s electrical system and the trailer’s brake system. It shows where the electric current flows and where the various components are located.
When it comes to electric trailer brakes, there are two main types of wiring diagrams: 7-way and 6-way. The 7-way diagram is the most common and is used for trailers with electric brakes and a separate battery for charging. The 6-way diagram is used for trailers with electric brakes but without a separate battery.
7-Way Electric Trailer Brakes Wiring Diagram
| Towing Vehicle | Trailer |
|---|---|
| Ground | Ground |
| Brake Controller Output | Brake Controller Input |
| Left Turn / Brake Lights | Left Turn / Brake Lights |
| Right Turn / Brake Lights | Right Turn / Brake Lights |
| Tail Lights | Tail Lights |
| Auxiliary Power | Battery Charge |
| Back-up Lights | N/A |
When wiring electric trailer brakes using a 7-way diagram, it is important to follow the diagram precisely. Each connection must be made to the corresponding component on the towing vehicle and the trailer.
It is also important to ensure that the wiring is secure and protected from potential damage caused by weather, road debris, or other factors.
6-Way Electric Trailer Brakes Wiring Diagram
| Towing Vehicle | Trailer |
|---|---|
| Ground | Ground |
| Brake Controller Output | Brake Controller Input |
| Left Turn / Brake Lights | Left Turn / Brake Lights |
| Right Turn / Brake Lights | Right Turn / Brake Lights |
| Tail Lights | Tail Lights |
| N/A | Battery Charge |
The 6-way wiring diagram for electric trailer brakes is similar to the 7-way diagram, but does not include an auxiliary power connection. The battery charge connection is used instead to power the brakes.
FAQ
What is an electric trailer brake?
An electric trailer brake is a type of braking system that uses an electric current to activate the brakes on a trailer. This current is sent from the towing vehicle to the trailer’s brakes through a wiring system.
How do electric trailer brakes work?
When the driver applies the brakes in the towing vehicle, an electric current is sent to the trailer’s brakes through a wiring system. This current activates the brakes on the trailer, causing it to slow down and stop.
Why are electric trailer brakes important?
Electric trailer brakes are important for ensuring safe and efficient stopping of a trailer attached to a towing vehicle. They provide additional braking power and help to prevent damage to both the towing vehicle and the trailer.
Can I install electric trailer brakes myself?
It is possible to install electric trailer brakes yourself, but it is important to have a wiring diagram and to follow it precisely. If you are not familiar with electrical wiring or do not feel confident in your abilities, it is recommended to seek the assistance of a professional.
