If you own a trailer, it is essential to understand the wiring diagram that connects your vehicle to the trailer. One of the most commonly used wiring diagrams is the 7 blade flat wiring diagram. This article will help you understand what this diagram is and how it works.
What is a 7 Blade Flat Wiring Diagram?
A 7 blade flat wiring diagram is a type of wiring diagram that connects a vehicle to a trailer. It includes seven wires that are color-coded to help identify each one. Each wire performs a specific function, and together they ensure that the trailer’s lights, brakes, and other electrical components work properly.
The seven wires in a 7 blade flat wiring diagram are:
| Wire Color | Function |
|---|---|
| White | Ground |
| Brown | Tail/Marker Lights |
| Yellow | Left Turn/Brake |
| Green | Right Turn/Brake |
| Blue | Brake Controller Output |
| Black | Battery Charge |
| Red | Reverse Lights (optional) |
How Does a 7 Blade Flat Wiring Diagram Work?
A 7 blade flat wiring diagram works by connecting the seven wires to the corresponding electrical components on the trailer. The white wire is connected to the trailer’s frame, providing a ground for the electrical system. The brown wire connects to the tail and marker lights, while the yellow and green wires connect to the left and right turn signals and brake lights.
The blue wire connects to the trailer’s brake controller, which applies the brakes when the driver steps on the brake pedal. The black wire connects to the trailer’s battery, providing a charge to the battery when the vehicle is running. Lastly, the optional red wire connects to the reverse lights, which illuminate when the driver puts the vehicle in reverse.
