A trailer wiring diagram is essential for anyone who intends to tow a trailer. It ensures that the trailer lights are working correctly and that the signals from the towing vehicle are being sent to the trailer. This article outlines the details of the 6 point trailer wiring diagram.
What is a Trailer Wiring Diagram?
A trailer wiring diagram is a visual representation of the electrical connections between a towing vehicle and a trailer. It specifies the color-coding of the wires, the connections between the various components, and the electrical functions of each wire. A trailer wiring diagram ensures that the trailer lights work when they are supposed to and that the towing vehicle can communicate with the trailer.
Why is a Trailer Wiring Diagram Important?
Trailer wiring diagrams are important because they prevent potentially hazardous situations on the road. Without a proper wiring diagram, the trailer lights may not function correctly, which could lead to accidents. A trailer wiring diagram is crucial for knowing which wires to connect and how to connect them in the correct order. It is also essential for identifying any wiring problems that may occur during towing.
How to Read a Trailer Wiring Diagram
Reading a trailer wiring diagram is not difficult. The diagram consists of a series of symbols representing the various components of the wiring system. The symbols are typically color-coded to indicate the function of each wire. A key to the symbols is provided on the diagram, which explains what each symbol represents.
The wiring diagram is typically broken down into sections, with each section representing a specific function of the system. For example, the diagram may have sections for the left turn signal, right turn signal, brake lights, and running lights. Each section will have its own set of symbols, which correspond to the appropriate wires in the system.
The 6 Point Trailer Wiring Diagram
The 6 point trailer wiring diagram is a common wiring configuration for trailers. It consists of six wires that are color-coded to indicate their function:
| Wire Color | Function |
|---|---|
| Brown | Tail/Marker Light |
| Yellow | Left Turn Signal |
| Green | Right Turn Signal |
| White | Ground |
| Blue | Brake |
| Red | Battery/Charge |
Brown Wire
The brown wire is connected to the tail/marker lights on the trailer. These lights are typically located on the rear of the trailer and indicate the outline or edge of the trailer to other drivers on the road.
The brown wire is also used to power the license plate light on the trailer, if it has one.
Yellow Wire
The yellow wire is connected to the left turn signal on the towing vehicle. This wire signals the left turn signal on the trailer when activated by the towing vehicle.
The left turn signal is typically indicated by a flashing light on the rear of the trailer on the left-hand side.
Green Wire
The green wire is connected to the right turn signal on the towing vehicle. This wire signals the right turn signal on the trailer when activated by the towing vehicle.
The right turn signal is typically indicated by a flashing light on the rear of the trailer on the right-hand side.
White Wire
The white wire is the ground wire for the trailer. It is connected to the trailer frame and provides an electrical ground for the trailer’s electrical system.
The white wire is also used to ground the trailer’s brake system, if applicable.
Blue Wire
The blue wire is connected to the trailer’s electric brake system. This wire sends a signal from the towing vehicle to the trailer to activate the trailer’s brakes when the towing vehicle’s brakes are applied.
Red Wire
The red wire is connected to the trailer’s battery or charging system. This wire charges the trailer’s battery or provides power to the trailer’s electrical system when the towing vehicle is running.
FAQ
What if my Trailer Wiring Diagram is Different?
