What is a Reese Trailer Plug Wiring Diagram and How is it Used?
A Reese Trailer Plug Wiring Diagram is a schematic that illustrates the specific color-coding and function of each wire within a Reese trailer connector. These connectors are designed to provide a standardized way to transmit power and signals from the towing vehicle to the trailer's electrical components, primarily its lights. These diagrams are indispensable tools for both professional mechanics and DIY enthusiasts alike. They take the guesswork out of trailer wiring, ensuring that functions like brake lights, turn signals, running lights, and even auxiliary power are correctly routed.
The use of a Reese Trailer Plug Wiring Diagram simplifies the installation and maintenance process significantly. Instead of relying on trial and error, you can consult the diagram to identify which wire corresponds to which function. For example, you'll typically find:
- Running Lights: Often a brown wire, this illuminates the trailer's marker lights.
- Left Turn/Stop Light: Typically a yellow wire, controlling the left turn signal and the brake light on that side.
- Right Turn/Stop Light: Usually a green wire, controlling the right turn signal and the brake light on that side.
- Ground: Essential for completing the circuit, usually a white wire.
- Brake Controller Power: This wire (often blue) provides power to an aftermarket trailer brake controller.
- Reverse Lights: Sometimes a purple wire, this activates the trailer's reverse lights when the vehicle is in reverse.
Understanding these connections is paramount for safety . Incorrect wiring can lead to malfunctioning lights, which can result in fines, accidents, and a hazardous towing experience. The diagram ensures that when you hit your brakes, the trailer's brake lights illuminate, and when you signal a turn, the corresponding lights on the trailer flash.
The Reese Trailer Plug Wiring Diagram typically comes in a few common configurations, with the 4-way, 5-way, 6-way, and 7-way being the most prevalent. Each offers a different number of circuits for various trailer needs:
| Connector Type | Common Functions |
|---|---|
| 4-Way Flat | Tail/Running Lights, Left Turn, Right Turn, Ground |
| 5-Way Flat | Functions of 4-way plus: Auxiliary Power or Reverse Lights |
| 6-Way Round | Functions of 4-way plus: Electric Brakes and Auxiliary Power |
| 7-Way RV Blade | Functions of 6-way plus: Trailer Battery Charge/Breakaway Battery Charge |
By referencing the specific Reese Trailer Plug Wiring Diagram for your connector type, you can confidently connect each wire to its corresponding terminal on both your vehicle and your trailer. This systematic approach prevents frustrating troubleshooting sessions and ensures your trailer's electrical system operates as intended.
