Wiring Harness
The first step in installing a trailer wiring harness on your 2020 Ford Explorer is to purchase the correct harness for your vehicle. There are a number of different wiring harnesses available, depending on the specific make and model of your vehicle, so be sure to choose the correct one.
Once you have your wiring harness, the next step is to install it. This will require some basic tools, such as wire cutters and strippers, pliers, and a socket set. You’ll also need to follow the instructions that come with your wiring harness, as the installation process can vary depending on the specific make and model of your vehicle.
That said, most wiring harnesses are relatively simple to install. You’ll typically need to locate the wiring harness on your vehicle, which is usually located near the rear bumper. From there, you’ll need to identify the wires that correspond to each of the trailer lights (brake lights, turn signals, etc.), and connect them to the appropriate wires on your wiring harness.
Once you’ve installed your wiring harness, be sure to test it to make sure that all of the trailer lights are working properly. This will ensure that you can tow your trailer safely and legally.
