Buying Guide for 4 Pin Trailer Plug

Understanding the Basics

When I first started towing, I quickly learned that a reliable connection between my vehicle and trailer was essential. The 4 pin trailer plug is the most common type used for basic lighting functions. It connects the electrical systems of the towing vehicle and the trailer, ensuring that the lights work correctly.

Identifying Your Needs

Before diving into options, I had to assess my specific needs. I considered the type of trailer I would be using and the functions I required. Typically, a 4 pin plug supports basic functions like tail lights, turn signals, and brake lights. If I ever needed additional features, I would need to look beyond the 4 pin system.
