The trailer wiring diagram for the 2018 RAM 1500 is fairly straightforward, but there are still some things that you need to know. The wiring diagram consists of several components, including the trailer connector, the wiring harness, the fuse box, and the brake controller.
The Trailer Connector
The trailer connector is the part of the wiring diagram that connects the truck to the trailer. It consists of several wires that are color-coded based on their function. The most common types of trailer connectors are the 4-pin, 5-pin, 6-pin, and 7-pin connectors, depending on the size and type of trailer you are towing.
The 2018 RAM 1500 comes equipped with a 7-pin trailer connector, which is the most common type of connector for larger trailers. The 7-pin connector includes wires for the running lights, brake lights, turn signals, and ground, among other things.
The Wiring Harness
The wiring harness is the part of the trailer wiring diagram that connects the trailer connector to the various components of the truck. The harness is color-coded to match the trailer connector, and includes wires for the brake controller, tail lights, and other components.
The 2018 RAM 1500 comes with two wiring harnesses: one for the truck and one for the trailer. The truck harness is already installed on the vehicle, while the trailer harness needs to be installed separately.
The Fuse Box
The fuse box is an important part of the trailer wiring diagram, as it provides power to the various components of the trailer. It includes several fuses that are designed to protect the circuitry from damage in case of a short circuit or other electrical malfunction.
It is important to note that the fuses in the fuse box have different ratings, depending on their function. Be sure to check the owner’s manual for the correct fuse rating for each component of the trailer.
The Brake Controller
The brake controller is an essential component of the trailer wiring diagram, as it is responsible for controlling the brakes on the trailer. It is connected to the wiring harness and receives signals from the truck’s brake system in order to activate the trailer brakes when needed.
There are two types of brake controllers: time-delay and proportional. Time-delay controllers apply the trailer brakes after a set amount of time, while proportional controllers adjust the brake force based on the vehicle’s speed.
