Trailer Harness Wiring Colors have a deep importance when it comes to safely towing your trailer. Knowing the individual wires and their functions is imperative in maintaining the security of both your car and the trailer. Wiring a trailer has become much easier with the advancement of technology, but one thing that has remained consistent is the color coding.

The most important part of wiring a trailer harness is knowing the exact purpose of each of the colored wires. The commonly used colors for trailer wiring are white, black, yellow, green and red. Each color serves a distinct purpose and the knowledge of each of their functions is essential. Let's take a look at the different color codes and their roles.

White is designated as the ground wire and should always be connected directly to the trailer frame or the bare metal surface of a trailer. This wire serves as a common link between all the other wires connecting the components of your trailer. Black is designated as the hot wire, carrying the electricity required to operate different components. Yellow is designated as the left-turn wire and is used to control the left turn signal, while green is designated to control the right-turn signal. Finally, red is designated for tail lights powered with a 12-volt power source. Knowing the proper use of these wiring colors and ensuring their correct connection with the trailer frame is an essential practice when it comes to safely towing your trailer.
