The Ground Wire
The ground wire connects the trailer's lighting system to the towing vehicle's chassis. It serves as a return path for the electrical current, allowing the trailer's lights to function correctly. The ground wire is usually white or grey, and it should be connected securely to the trailer's metal frame.
The Left Turn Signal Wire
The left turn signal wire is responsible for powering the trailer's left turn signal light. It is usually yellow in color, and it should be connected to the towing vehicle's left turn signal wire using a connector plug.
The Right Turn Signal Wire
Similar to the left turn signal wire, the right turn signal wire powers the trailer's right turn signal light. It is usually green in color, and it should be connected to the towing vehicle's right turn signal wire using a connector plug.
The Taillight Wire
The taillight wire powers the trailer's taillights, brake lights, and license plate light. It is usually brown in color, and it should be connected to the towing vehicle's taillight wire using a connector plug.
Wiring Color Codes
Understanding the wiring color codes is crucial for anyone installing a 4-wire diagram. The codes ensure that each wire is connected to the correct component, thus preventing any electrical mishaps. Below are the standard wiring color codes for a 4-wire diagram:

- Right Turn Signal Wire - Green
- Taillight Wire - Brown
Installation Process
The installation process for a 4-wire diagram is relatively simple and straightforward. Here are the steps involved:
- Locate the towing vehicle's wiring harness and identify the four wires (ground, left turn signal, right turn signal, and taillight).
- Attach the connector plug to the end of each wire using a wire crimper. Ensure that each wire is connected to the corresponding component (ground wire to the trailer's metal frame, left turn signal wire to the left turn signal light, etc.).
- Connect the connector plugs to the corresponding sockets on the trailer's lighting system.
- Test the trailer's lights to ensure that they are functioning correctly. If any issues arise, double-check the wiring connections and correct any mistakes.
Final Thoughts
The 4-wire diagram is an effective and straightforward wiring system for trailers. It ensures that the trailer's lighting system is synchronized with that of the towing vehicle, enabling the driver to signal their intentions effectively. Proper installation is crucial for this system to work correctly, so be sure to follow the guidelines outlined above.
