When it comes to towing trailers, having the proper wiring is crucial for safety and functionality. One of the most popular wiring configurations is the 6 wire round trailer wiring diagram. In this article, we will discuss the basics of this type of wiring and provide a step-by-step guide for installation.
What Is The 6 Wire Round Trailer Wiring Diagram?
The 6 wire round trailer wiring diagram is a configuration that uses six wires to connect the trailer to the towing vehicle. It is used for trailers with multiple functions such as running lights, brake lights, turn signals, and reverse lights. The 6 wires are color-coded and have specific functions, making it easy to connect the trailer correctly.
The Colors and Functions of the 6 Wires
The colors and functions of the 6 wires in the round trailer wiring diagram are as follows:
| Wire Color | Function |
|---|---|
| White | Ground |
| Brown | Tail Lights |
| Yellow | Left Turn Signal |
| Green | Right Turn Signal |
| Blue | Brake Lights |
| Black | Reverse Lights |
It is important to note that the wire colors may vary depending on the manufacturer, so it is always recommended to use a wiring diagram specific to your trailer and towing vehicle.
Step-by-Step Guide for 6 Wire Round Trailer Wiring Installation
Before starting the installation process, make sure you have the necessary tools and supplies:
- 6-way round trailer connector
- Wire cutters/strippers
- Electrical tape
- Heat shrink tubing
- Butt connectors
- Soldering iron and solder (optional)
Step 1: Prepare the Wires
Cut and strip the insulation from the ends of each wire. Make sure to leave enough length to reach the connector with some slack. Use the wire stripper tool to strip about ¾” to 1” of insulation from the end of each wire, exposing the bare copper wire beneath.
Step 2: Connect the Wires to the Connector
Using the diagram as a guide, attach each wire to the appropriate terminal on the 6-way round trailer connector. Use a butt connector to crimp the wire to the connector, then apply electrical tape or heat shrink tubing to seal the connection. Repeat this process for each wire.
Step 3: Test the Connections
Once all wires are attached to the connector, test each function to ensure that it is working properly. Turn on the towing vehicle’s lights and check that the trailer’s lights are working as they should. Check the brake lights, turn signals and reverse lights, in particular.
Frequently Asked Questions About 6 Wire Round Trailer Wiring Diagram
Q: What is the maximum weight that can be towed with a 6 wire round trailer wiring diagram?
A: The maximum weight that can be towed with a 6 wire round trailer wiring diagram is dependent on the towing vehicle’s towing capacity and the trailer’s weight. Make sure to follow the manufacturer’s guidelines and never exceed the recommended weight limit.
Q: Can I connect a 4-wire trailer to a 6-wire round trailer wiring diagram?
