Buying Guide for Best 4 pin round trailer connector

Types of 4 Pin Round Trailer Connectors

When looking for the best 4 pin round trailer connector, it’s important to know what type of connector is right for your vehicle and trailer. There are two main types of 4 pin round trailer connectors available: standard and heavy-duty. Standard connectors are typically used with small trailers, while heavy-duty connectors are designed for larger loads.

Standard 4 Pin Round Trailer Connectors: These connectors are typically smaller than their heavy-duty counterparts and feature the following four pins: left turn signal, right turn signal, brake light, and ground. They are designed for trailers with a maximum load capacity of 3,500 lbs. or less.

Heavy-Duty 4 Pin Round Trailer Connectors: These connectors have a higher load capacity than standard models and feature the same four pins as standard models (left turn signal, right turn signal, brake light, and ground). They can handle a maximum load capacity of 7,000 lbs. or more.

Things to Consider When Buying a 4 Pin Round Trailer Connector

Before purchasing a 4 pin round trailer connector, there are several factors you should consider in order to ensure you get the best product for your needs.

Durability: Make sure that the connector you choose is made from high-quality materials that can stand up to wear and tear over time without becoming brittle or breaking down easily. Look for connectors made from corrosion-resistant metals such as brass or stainless steel for maximum durability.

Wiring Requirements: Before selecting a connector, make sure that it meets the wiring requirements of your vehicle and trailer. If you’re unsure what type of wiring is needed, consult with an automotive technician or check your vehicle’s owner’s manual to be sure that you get the appropriate wiring setup for your needs.

Cost: The cost of a 4 pin round trailer connector will vary depending on brand, quality and features included in the product. Generally speaking, it’s best to opt for a higher quality product as these tend to be more durable and reliable in the long run than lower cost options which may not last as long or be as reliable over time.

Installation Tips

2) Carefully disconnect existing wiring from both vehicles;

3) Cut back any exposed wires;

8) Test connections before use by turning on lights/signals on both vehicles simultaneously;

9) Check connections periodically during use to ensure they remain secure (optional).
