The Necessity of a 7 Way Round Trailer Plug
As an avid traveler and outdoor enthusiast, I have had my fair share of experiences with trailers. Whether it’s hauling my camping gear or towing my boat to the lake, a reliable trailer is essential for any successful trip. And when it comes to connecting the trailer to my vehicle, there is one crucial component that I can’t do without – the 7 way round trailer plug.
The 7 way round trailer plug, also known as the RV plug or blade connector, is a standard connection system used for most trailers in North America. It consists of seven pins that provide power and signal transfer between the towing vehicle and the trailer. This plug is necessary for several reasons.
Firstly, the 7 way round trailer plug allows for easy and secure communication between the towing vehicle and the trailer. It provides connections for essential functions such as braking, taillights, turn signals, reverse lights, and electric brakes. Without this connection, it would be challenging to control and maneuver a trailer on the road.
Secondly, having a standard 7 way round trailer plug ensures compatibility with different vehicles and trailers. Whether I’m borrowing a friend’s truck or renting a new trailer, I know that
My Buying Guide on ‘7 Way Round Trailer Plug’
As an experienced RV owner, I have come across different types of trailer plugs over the years. One of the most versatile and commonly used plugs is the 7 way round trailer plug. This type of plug allows you to connect your trailer to the towing vehicle and transfer power, signals, and lights. In this buying guide, I will share my knowledge and experience on what to look for when purchasing a 7 way round trailer plug.
Durability
The first thing I consider when buying any RV equipment is its durability. A 7 way round trailer plug should be able to withstand harsh weather conditions and constant wear and tear from frequent use. Look for plugs made from high-quality materials such as heavy-duty plastic or metal. They should also be corrosion-resistant to ensure longevity.
Compatibility
Before purchasing a 7 way round trailer plug, make sure it is compatible with your towing vehicle’s wiring system. There are two types of wiring systems – blade style and pin style. The blade-style has flat contacts while the pin-style has round contacts. Check your vehicle’s manual or consult with a professional to determine which type you need.
Number of Pins
The standard 7 way round trailer plug has seven pins, but there are variations with additional pins for specific functions such as reverse lights or electric brakes. Determine which functions you need for your trailer and choose a plug with the appropriate number of pins.
Water Resistance
If you frequently travel in wet or rainy conditions, it is crucial to have a water-resistant 7 way round trailer plug. Look for plugs with rubber gaskets or seals around the connections to prevent water from entering and damaging the electrical components.
Ease of Installation
Installing a new 7 way round trailer plug can be challenging if you are not familiar with wiring systems. Consider purchasing a plug that comes with clear instructions or opt for a pre-wired harness that can easily be plugged into your existing system.
Price
The price of a 7 way round trailer plug can vary depending on its features and quality. It is essential to set a budget beforehand and compare prices from different brands before making a purchase. Remember, investing in a high-quality product may save you money in the long run by avoiding frequent replacements.
Warranty
A warranty is an important factor to consider when buying any RV equipment, including a 7 way round trailer plug. Look for brands that offer at least one year warranty against defects or malfunctions.
In conclusion, purchasing a 7 way round trailer plug may seem like a small decision, but it plays an essential role in ensuring safe and efficient towing experiences. By considering factors such as durability, compatibility, water resistance, ease of installation, price, and warranty, you can make an informed decision on which 7-way round trailer plug best suits your needs.
