The 2019 Ford Ranger is a versatile and powerful truck that is perfect for towing and hauling cargo. If you are planning on towing a trailer with your Ranger, you will need to have a high-quality wiring harness installed. The wiring harness is responsible for transmitting the electrical signals between your truck and your trailer, allowing you to control your trailer’s lights, brakes, and other systems.
What is a Wiring Harness?
A wiring harness is a collection of wires, connectors, and other components that are designed to transmit electrical signals between different parts of a vehicle. In the case of a trailer wiring harness, it is specifically designed to transmit electrical signals between your truck and your trailer. This allows you to control your trailer’s lights, brakes, and other systems while you are driving.
Without a wiring harness, you would need to manually connect the electrical systems of your truck and your trailer together, which can be time-consuming and potentially dangerous.
