This type of plug, also known as a RV style connector, has seven pins that connect the trailer’s electrical system to the vehicle’s.

After trying out various options, I have come to realize that the 7 way round trailer plug is the most efficient and versatile choice for all my towing needs. In this buying guide, I will share with you everything you need to know before purchasing a 7 way round trailer plug.
What is a 7 Way Round Trailer Plug?
A 7 way round trailer plug, also known as a 7 pin trailer connector, is an electrical connection between your vehicle and trailer. It consists of seven pins which are used to transmit power from your vehicle’s battery to your trailer’s lights, brakes, and other electrical components. The round shape of the plug provides a secure connection and prevents any accidental disconnections while on the road.
Why Choose a 7 Way Round Trailer Plug?
There are several reasons why I highly recommend a 7 way round trailer plug:
- Versatility: A 7 way round trailer plug can be used on various types of trailers such as utility trailers, campers, horse trailers, and boat trailers.
- Easy to Install: Most modern vehicles are equipped with a factory-installed brake controller and wiring harness compatible with a 7 way round trailer plug. This makes installation quick and hassle-free.
- Durability: The round design of the plug makes it more resistant to wear and tear compared to flat connectors. It can withstand harsh weather conditions and rough handling without compromising its function.
- Better Electrical Connection: The number of pins in a 7 way round trailer plug allows for better transmission of power compared to other types of connectors. This ensures that all your lights and brakes function properly while towing.
Things to Consider Before Buying
Purchasing the right 7 way round trailer plug can make all the difference in your towing experience. Here are some important factors to consider before making your purchase:
- Type of Vehicle: Not all vehicles come with factory-installed wiring harness compatible with a 7 way round trailer plug. Make sure to check if your vehicle has this feature before purchasing.
- Towing Capacity: It is crucial to know your vehicle’s towing capacity before selecting a trailer plug. Make sure that the combined weight of your vehicle and loaded trailer does not exceed its maximum towing capacity.
- Durability: Look for plugs made from high-quality materials such as heavy-duty plastic or metal for long-lasting durability.
- Cable Length: Consider how far apart your vehicle’s hitch receiver is from where you will be plugging in the connector on your trailer. Make sure that the cable length is long enough for easy connection without being too long that it drags on the ground.
Tips for Maintenance
To ensure that your 7 way round trailer plug stays in good condition, here are some maintenance tips:
- Clean Regularly: Dirt or debris inside the connector can cause poor connections or even corrosion over time. Clean it regularly using an electrical contact cleaner or rubbing alcohol.
- Lubricate Pins: Use dielectric grease or petroleum jelly on each pin before connecting to prevent corrosion and maintain smooth connections.
- Routinely Check Connections:Routinely inspect connections between your vehicle and trailer for any signs of wear or damage. Replace any worn out parts immediately.
I hope this buying guide has been helpful in understanding everything you need to know about purchasing a 7 way round trailer plug. With its versatility, durability, and ease of installation, it is undoubtedly an excellent investment for all your towing needs!
