Why I Believe a 7 Way Trailer Wire Plug is Essential

As someone who has owned and operated multiple trailers, I can confidently say that a 7 way trailer wire plug is an absolute necessity. This type of plug, also known as a round pin connector, allows for the proper connection between your trailer and towing vehicle. Without it, you risk not only inconvenience, but also safety hazards on the road.

First and foremost, a 7 way trailer wire plug allows for all necessary electrical components to be connected between your trailer and towing vehicle. This includes brake lights, turn signals, and tail lights. Without these functions properly working, you are putting yourself and others on the road at risk. In addition, some states have laws requiring trailers to have functional brake lights and turn signals in order to be legally towed.

Furthermore, a 7 way trailer wire plug also allows for the connection of electric brakes on your trailer. These brakes are crucial in providing additional stopping power when towing heavy loads. Without them, you could risk losing control of your trailer while driving down steep inclines or in emergency braking situations.

Another reason why I believe a 7 way trailer wire plug is essential is because it allows for easy troubleshooting in case of electrical issues.

My Buying Guide on ‘7 Way Trailer Wire Plug’

As someone who has owned and used multiple trailers, I understand the importance of having a reliable and efficient wiring system. A 7 way trailer wire plug is a crucial component that allows you to connect your trailer’s electrical system to your vehicle, providing power to essential functions such as brake lights, turn signals, and taillights. In this buying guide, I will share my experience and provide you with all the necessary information to help you choose the right 7 way trailer wire plug for your needs.

What is a 7 Way Trailer Wire Plug?

A 7 way trailer wire plug is a connector that has seven pins or blades designed to transfer power and signals between your vehicle and trailer. Each pin or blade serves a specific function, including brake lights, turn signals, taillights, electric brakes, reverse lights, and auxiliary power. This type of wiring system is commonly used for trailers that are larger in size and require more electrical power.

Factors to Consider

Before purchasing a 7 way trailer wire plug, there are several factors you should consider to ensure that it meets your needs.

Compatibility

The first thing you need to check is if the 7 way trailer wire plug is compatible with your vehicle’s wiring system. Most plugs come with universal compatibility, but it’s always best to double-check before making a purchase.

Durability

Since the wiring system will be exposed to various elements such as rain and road debris, it’s essential to choose a durable option. Look for plugs made from high-quality materials like heavy-duty plastic or metal for long-lasting performance.

Number of Pins/Blades

While most 7 way trailer wire plugs come with seven pins/blades as standard, some may have additional pins/blades for added functionality. Consider the type of trailer you will be using and its electrical requirements before deciding on the number of pins/blades needed.

Waterproofing

If you frequently tow your trailer through wet conditions or submerge it in water when launching boats or jet skis, waterproofing should be a top priority. Look for plugs that come with weatherproof seals or are fully enclosed to prevent water damage.

Additional Features

Aside from these key factors, there are also some additional features that you may find useful in a 7 way trailer wire plug.

LED Indicator Lights

Some plugs come equipped with LED indicator lights that alert you if there are any faults in the wiring system. This feature can save you time troubleshooting issues with your trailer’s lights.

Dust Covers

Dust covers provide extra protection against dirt and debris buildup in the pins/ blades when not in use. They also help prolong the life of your plug by preventing corrosion.

Installation Process

While installation processes may vary depending on your vehicle’s make and model, most 7 way trailer wire plugs follow similar installation steps. However, if you’re not confident in installing it yourself, seek professional assistance from an auto electrician or mechanic.

1) Start by disconnecting your vehicle’s battery.
2) Locate the mounting location for the plug on your vehicle.
3) Drill holes (if needed) for mounting screws.
4) Connect each pin/blade according to their designated function.
5) Securely mount the plug onto your vehicle.
6) Test all functions by connecting your vehicle’s battery back on and plugging in your trailer.

Price Range

The price range for a good quality 7 way trailer wire plug can vary between $10-$50 depending on its features and durability. It’s essential not to compromise on quality as cheaper options may not last long or cause issues with your vehicle’s electrical system.

Conclusion

Purchasing a 7 way trailer wire plug may seem like a small decision compared to other parts of owning a trailer. However, choosing the right one can save you time and money in the long run while ensuring safe towing experiences. By considering compatibility, durability, number of pins/blades needed, additional features,and installation process,you can make an informed decision when selecting a 7 way trailer wire plug that meets all your needs
