When it comes to towing a trailer, having the proper wiring is essential to ensure that your trailer lights work correctly and you can safely transport your cargo. One of the most common types of trailer wiring is the 4 plug trailer wiring system. This system is typically used on smaller trailers and is easy to install and use.
With a 4 plug trailer wiring system, you will have four wires that connect to your vehicle’s electrical system. These wires typically include a ground wire, a tail light wire, a left turn signal wire, and a right turn signal wire. By connecting these wires properly, you can ensure that your trailer lights will work in sync with your vehicle’s lights.
