Trailer wiring can be confusing, especially when it comes to figuring out the right wiring diagram for your trailer. If you’re looking for a 6 way round plug trailer wiring diagram, you’re in the right place. In this article, we’ll provide you with everything you need to know about wiring your trailer with a 6 way round plug. From the basics of trailer wiring to understanding the diagram itself, we’ll cover it all. Let’s get started!
What is a 6 way round plug trailer wiring diagram?
A 6 way round plug trailer wiring diagram is a diagram that shows you how to wire your trailer with a 6 way round plug. This type of plug is commonly used on some trailers and RVs. The diagram provides you with a visual representation of the wiring setup you need to follow to connect your trailer to your tow vehicle properly.
A 6 way round plug has 6 pins or connections that are numbered for easy identification. Each pin has a specific color code that corresponds to a specific wire. By following the diagram and connecting the right wires to the right pins, you’ll have a functional trailer that’s ready to hit the road.
The Basics of Trailer Wiring
Before we dive into the specifics of a 6 way round plug trailer wiring diagram, let’s go over some basic trailer wiring concepts that will help you better understand the diagram.
The 4-Wire Flat Wiring System
The most basic trailer wiring system is the 4-wire flat system. This system consists of four wires:
- Ground wire (white)
- Left turn and brake wire (yellow)
- Right turn and brake wire (green)
- Taillight wire (brown)
This system is typically used on small trailers, like utility trailers or boat trailers, and doesn’t require a brake controller.
The 7-Wire Round Wiring System
The 7-wire round system, also known as the RV-style wiring system, is more complex than the 4-wire flat system. It has seven wires instead of four:
- Ground wire (white)
- Left turn and brake wire (yellow)
- Right turn and brake wire (green)
- Taillight wire (brown)
- Brake wire (blue)
- Battery charge wire (black)
- Auxiliary wire (purple)
This system is used on larger trailers, like travel trailers or fifth wheel trailers, and requires a brake controller to operate the brakes.
The 6 Way Round Plug Wiring Diagram
Now that we’ve covered the basics, let’s take a look at the 6 way round plug trailer wiring diagram. The diagram is divided into three sections: the tow vehicle, the trailer, and the individual connections between them. Let’s break it down.
The Tow Vehicle Connections
The first section of the diagram shows the connections on the tow vehicle. It includes the following pins:
- Ground wire (white)
- Left turn and brake wire (yellow)
- Right turn and brake wire (green)
If your tow vehicle has separate turn signals and brake lights, you’ll need to use a converter box to combine the two signals into one wire. The combined wire will connect to the yellow pin on the plug.
The Trailer Connections
The second section of the diagram shows the connections on the trailer. It includes the following pins:
- Ground wire (white)
- Left turn and brake wire (yellow)
- Right turn and brake wire (green)
- Taillight wire (brown)
- Brake wire (blue)
- Battery charge wire (black)
If your trailer doesn’t have brakes, you can skip the blue wire. If you’re not using a battery on your trailer, you can skip the black wire.
The Individual Connections
The third section of the diagram shows the individual connections between the tow vehicle and trailer. It includes the following connections:
- Ground to ground (white to white)
- Left turn and brake to left turn and brake (yellow to yellow)
- Right turn and brake to right turn and brake (green to green)
- Taillight to taillight (brown to brown)
- Brake controller output to brake wire (blue to blue)
- Battery positive to battery charge wire (black to black)
Once you’ve made all of these connections, your trailer should be fully wired and ready to go!
