How To Easily Install 4 Wire Trailer Lights

Trailer lights are a necessary item on all trailers, big or small. They provide the necessary visibility and safety on the road. Installing 4 wire trailer lights is a task that can easily be done by a do-it-yourselfer. With the right tools and materials, you can have your lights installed quickly and correctly. This article will discuss the necessary steps to successfully install 4 wire trailer lights.

Gathering Tools and Materials

Before you can install your 4 wire trailer lights, you must gather the necessary tools and materials. The most important item is the trailer wiring harness. This will allow you to connect all of the wires from the trailer lights to the vehicle. You will also need a few basic tools such as a screwdriver, wire cutters, zip ties, and a drill. All of these items can be found at your local hardware store.

Installing the Wiring Harness

The first step in installing 4 wire trailer lights is to connect the trailer wiring harness to the vehicle. You will need to locate the connection points. Most vehicles have a hidden connection panel located somewhere near the rear of the vehicle. You can find the panel by consulting the owner’s manual. Once you have located the connection points, you will need to connect each wire from the trailer wiring harness. Make sure to follow the instructions included with the wiring harness.

Attaching the Lights

Once the wiring harness is connected to the vehicle, it is time to attach the trailer lights. You will need to start by connecting the red and white wires of the wiring harness to the corresponding wires on the trailer lights. After this is done, you should move on to the yellow and green wires. Connect the yellow wire to the right side turn signal and the green wire to the left side turn signal. Make sure to use zip ties or another reliable method to secure the wires.

Connecting the Ground Wires and Testing the Lights

The last step in installing the 4 wire trailer lights is to attach the ground wires. You will need to run one wire from each of the trailer lights to a chassis ground point. Once all of the ground wires are connected, you should test the lights by having someone sit inside the vehicle and turning on the lights. If the lights work correctly, then the installation has been successful.

Conclusion

Installing 4 wire trailer lights is not a difficult task, but it is important to take the necessary precautions. By following the steps outlined in this article, you can ensure that your trailer lights are properly installed and that they are providing the necessary visibility when on the road. With the right tools and materials, you can have your 4 wire trailer lights installed in no time.
