If you have a 2018 Dodge Ram and you need to make sure that the trailer wiring is installed correctly, you’re in the right place. In this article, we’ll cover everything you need to know about trailer wiring for your 2018 Dodge Ram, including a detailed wiring diagram and frequently asked questions.
What Is Trailer Wiring?
Trailer wiring allows your truck and trailer to communicate electrically, so you can safely tow your trailer. Without proper trailer wiring, you won’t be able to use your trailer’s lights, signals, or brakes. Every state in the US requires trailer lighting, so it’s important to have it installed correctly.
There are two primary types of trailer wiring: 4-pin and 7-pin. A 4-pin connector is typically used for lighter trailers, while a 7-pin connector is required for larger trailers with brakes. Your 2018 Dodge Ram will come equipped with a 4-pin connector, but you can upgrade to a 7-pin connector if needed.
