My Buying Guide on ‘7 Way Plug Wire’

A 7 way plug wire is an essential component for connecting trailers, RVs, and other vehicles to a towing vehicle. With so many options available in the market, it can be overwhelming to choose the best one. In this guide, I will share my personal experience and provide some key factors to consider when buying a 7 way plug wire.

1. Know your vehicle’s wiring system

The first step in buying a 7 way plug wire is to know your vehicle’s wiring system. Some vehicles may have a 4 way or 5 way connector, while others may have a 6 way or 7 way connector. It is important to match the number of pins on your vehicle’s connector with the number of pins on the plug wire to ensure compatibility.

2. Consider the length

The length of the plug wire is another important factor to consider. It should be long enough to comfortably reach from your towing vehicle’s electrical socket to the trailer’s electrical socket without any tension or strain. Measure the distance between both sockets before purchasing a plug wire.

3. Check for durability

A good quality plug wire should be durable enough to withstand harsh weather conditions and frequent use without getting damaged. Look for wires made from high-quality materials such as copper or aluminum, which are known for their durability and ability to carry high amounts of current.

4. Consider waterproofing

If you often tow your trailer through wet or rainy conditions, it is important to choose a waterproof plug wire. This will prevent any damage caused by water exposure and ensure smooth functioning of your electrical connections.

5. Look for additional features

Some 7 way plug wires come with additional features such as LED lights that indicate when there is proper electrical connection between both sockets, making it easier for you to troubleshoot any issues quickly.

6. Read reviews and compare prices

Before making a purchase, it is always helpful to read reviews from other buyers who have used the product. This will give you an idea about its performance and durability. Additionally, compare prices from different brands before making a decision.

7. Buy from reliable sources

To ensure that you are getting a genuine and high-quality product, always buy from reliable sources such as reputable online retailers or authorized dealers.

I hope this guide has been helpful in providing some key points to consider when purchasing a 7 way plug wire. By keeping these factors in mind, you can make an informed decision and choose the right plug wire for your towing needs.
