What is a Four Prong Trailer Plug?

A four prong trailer plug is an electrical connector that is used to connect the wiring of a towing vehicle to the lighting and braking systems of a trailer. It has four pins or terminals that correspond to the different functions of the trailer, namely, left turn signal, right turn signal, brake lights, and ground.

Factors to Consider

Type of Trailer

The type of trailer you will be towing plays an important role in choosing the right four prong trailer plug. Some trailers may require additional pins or terminals for features such as electric brakes or reverse lights. Be sure to check your trailer’s wiring diagram before purchasing a plug.

Weather Resistance

If you will be using your trailer in different weather conditions, it is important to choose a four prong trailer plug that can withstand harsh elements. Look for plugs with rubber grommets or seals around the pins to prevent water and debris from getting inside.

Cable Length

The length of the cable connecting your vehicle’s wiring harness to the trailer plug is also an important factor to consider. Make sure it is long enough so that there is no strain on the wires when making turns or going over bumps.

Durability

A durable four prong trailer plug can save you time and money in the long run. Look for plugs made from high-quality materials such as heavy-duty plastic or metal. They should also come with secure connections to prevent any loose wires while towing.

Conclusion
