When it comes to connecting trailers to cars, safety must be a priority.

Proper wiring means having the right wire size, type, and color coded in accordance with the appropriate diagram. Understanding the wiring installation guidelines can help minimize common mistakes and ensure safe operation of your trailer.

Understanding the Different Types of Wiring

Wiring diagrams are very useful in helping to accurately install the wiring connection between your vehicle and trailer. First, you need to be aware of the different types of wires needed when installing a trailer wiring system. The trailer wiring consists of two main types: flat four connector wiring and round seven connector wiring. The flat four connector consists of two large and two small pins, while the round seven connector consists of seven round pins placed in a semi-circular formation. Depending on your application, you may need to use a combination of both types of wires in order for the connection to work correctly.

Overview of Wire Color Codes

When following a wiring diagram, it is important to identify the proper wire color codes in order to make the connection. The 2018 Subaru Forester is equipped with specific color-coded wires for trailer wiring. For example, the white, black, and green wires provide power for the turn signals, brakes, and other functions. The yellow and brown wires provide power for the backup lights and tail lights, while the blue and red wires are dedicated to the auxiliary power supply.

A Closer Look At Trailer Connectors

In addition to understanding the different types of wire used, it also helps to know more about the trailer connectors. The trailer connectors provide a reliable connection point between the trailer and the car. The Subaru Forester has standard four-way flat connectors and seven-way round connectors, so you need to ensure the right ones are used for the job.

The four-way connectors are designed for basic power transfer for basic illumination systems and are typically used for turn signals, stoplights and tail lights. The seven-way round connectors have additional capability for electronic brake controls, providing power for the electric brakes found on most trailers.

Where to Find the Wiring Diagram?

If you need a copy of the wiring diagram for the Subaru Forester, it’s easy to find and download one. You can find them at Subaru dealerships, as well as on third-party websites. However, be sure to verify that the diagram you are downloading is for the correct year and make.

Knowing the 2018 Subaru Forester Trailer Wiring Diagram will save you time, money and energy when preparing for your upcoming travels. Proper wiring ensures that all systems are properly connected, allowing you to enjoy a safe, stress-free journey.
