It’s been a long time coming, but the 2018 GMC Sierra 1500 has finally arrived, and with it comes a number of exciting changes. One of the most noteworthy is the addition of an all-new trailer wiring diagram to simplify the process of hooking up trailers to your truck. This comprehensive diagram shows you how to connect the trailer’s seven-way connector to your truck’s four-way connector, providing a complete solution for those looking to take their cargo on the road.
For those unfamiliar with trailer wiring, the seven-way connector is typically used to power trailer brakes, while the four-way connector is used to power the tail lights and other electrical components. The wiring diagram will make connecting the two connectors much simpler, eliminating the need to splice multiple wires together. Additionally, it will also let you know which wire should be connected to which pin in order to ensure proper functionality.
The addition of the trailer wiring diagram is just one of many features of the 2018 GMC Sierra 1500 that makes it stand out from the competition. It also features a strong V6 engine, eight-speed transmission, and a spacious interior, making it a great choice for those who need a reliable workhorse truck that can handle large loads.
In addition to being able to easily and safely tow a trailer, the new GMC Sierra 1500 also features a variety of features designed to make life easier, including an eight-inch infotainment system, Apple CarPlay and Android Auto compatibility, and a variety of safety technologies such as forward collision warning and lane departure warning.
The trailer wiring diagram of the 2018 GMC Sierra 1500 is a great addition to an already impressive truck. With the addition of this feature, GMC has made it easier than ever to hook up a trailer and get on the road. Whether you’re looking for a reliable workhorse truck or a dependable family hauler, the 2018 GMC Sierra 1500 is sure to fit the bill.
