7 Pin Trailer Plug Buying Guide
When it comes to towing a trailer, the right wiring and electrical components are essential. One of the key components is the trailer plug, which connects the trailer's electrical system to the tow vehicle. There are several different types of trailer plugs available, but the 7 pin trailer plug is the most commonly used for towing larger trailers. In this guide, we'll explore everything you need to know to choose the right 7 pin trailer plug for your towing needs.
What is a 7 Pin Trailer Plug?
A 7 pin trailer plug is a connector that has seven pins or blades that are used to connect a trailer to a tow vehicle. The seven pins are used for different purposes:
- Ground: Pin 1 is for the ground wire, which is used to ground the trailer's electrical system to the tow vehicle.
- Left turn/brake: Pin 2 is for the left turn signal and brake lights.
- Right turn/brake: Pin 3 is for the right turn signal and brake lights.
- Tail/marker lights: Pin 4 is for the taillights and marker lights on the trailer.
- Brake controller: Pin 5 is for the brake controller, which is used to operate the electric brakes on the trailer.
- Battery: Pin 6 is for the battery, which is used to charge the trailer's battery while it's being towed.
- Back-up lights: Pin 7 is for the back-up lights on the trailer.
Why Use a 7 Pin Trailer Plug?
The 7 pin trailer plug is the most commonly used trailer plug for towing larger trailers because it provides all the necessary connections for the trailer's electrical system. The 7 pin plug allows for independent control of the left and right turn signals, the brake lights, and the taillights. It also includes a connection for the brake controller and a battery charge line, which are essential for towing trailers with electric brakes or trailers with onboard battery systems.
Types of 7 Pin Trailer Plugs
There are two main types of 7 pin trailer plugs: round and flat. The round plugs are typically used on larger trailers, while the flat plugs are used on smaller trailers. Here's a closer look at each type:
Round 7 Pin Trailer Plugs
Round 7 pin trailer plugs are the most common type of 7 pin plug and are typically used on larger trailers. They have a circular shape and feature seven pins or blades that are arranged in a circular pattern. These plugs are highly durable and weather-resistant, making them ideal for use in harsh conditions.
Flat 7 Pin Trailer Plugs
Flat 7 pin trailer plugs are typically used on smaller trailers and have a rectangular shape with seven pins or blades arranged in a straight row. These plugs are less durable than round plugs and are not as weather-resistant, making them better suited for use in less harsh conditions.
Choosing the Right 7 Pin Trailer Plug
When choosing a 7 pin trailer plug, there are several factors to consider. Here are some key things to keep in mind:
Compatibility
The first thing to consider when choosing a 7 pin trailer plug is compatibility. The plug must be compatible with both your trailer's electrical system and your tow vehicle's wiring harness. Make sure to check the owner's manual for both your trailer and tow vehicle to determine which type of plug is compatible.
Durability
The next thing to consider is the plug's durability. Look for plugs that are made from high-quality materials and are designed to withstand harsh weather conditions. Round plugs are generally more durable than flat plugs, so if you're towing a larger trailer or plan to tow in harsh conditions, a round plug may be a better option.
Functionality
Another important factor to consider is the plug's functionality. Make sure the plug has all of the necessary connections for your trailer's electrical system, including connections for the brake controller and battery charge line if needed. Some plugs may also come with additional features, such as built-in LED lights for better visibility.
Ease of Installation
Finally, consider the ease of installation when choosing a 7 pin trailer plug. Look for plugs that are easy to install and require minimal tools or expertise. Some plugs may come with installation instructions or even be pre-wired for easier installation.
Installation Tips
Once you've chosen the right 7 pin trailer plug, it's important to install it correctly to ensure safe and reliable towing. Here are some tips to keep in mind:
- Make sure the wiring harness and plug connections are clean and free of corrosion.
- Follow the wiring diagram for your trailer and tow vehicle to ensure proper connection.
- Test the connections for continuity and proper function before towing.
- Secure the wiring harness to prevent damage from vibration or movement during towing.
Conclusion
Choosing the right 7 pin trailer plug is essential for safe and reliable towing. Consider compatibility, durability, functionality, and ease of installation when choosing a plug for your trailer. Once you've chosen the right plug, make sure to install it correctly and test the connections before towing. With the right plug and proper installation, you can enjoy worry-free towing for years to come.
