Introduction
When it comes to towing a trailer, one of the most important things to get right is the wiring. The wiring diagram for a 4 wire trailer can be confusing for those who have never done it before, but it’s actually quite simple once you know what you’re doing.
The 4 Wires
The first thing to understand about a 4 wire trailer wiring diagram is what the 4 wires actually are. There are four wires that are used to connect the trailer to the towing vehicle: ground, left turn/brake, right turn/brake, and running lights.
Ground Wire
The ground wire is usually white and connects the trailer frame to the towing vehicle’s frame. This helps to provide a safe and reliable ground for the entire electrical system.
Left Turn/Brake Wire
The left turn/brake wire is usually yellow and connects to the left turn/brake light on the trailer. This wire is responsible for providing power to the left turn signal and brake lights when activated by the towing vehicle.
Right Turn/Brake Wire
The right turn/brake wire is usually green and connects to the right turn/brake light on the trailer. This wire is responsible for providing power to the right turn signal and brake lights when activated by the towing vehicle.
Running Lights Wire
The running lights wire is usually brown and connects to the running lights on the trailer. This wire provides power to the running lights so they can be seen at night or in low light conditions.
Wiring the Trailer
To wire the trailer, you will need to first disconnect the trailer from the towing vehicle. Next, you will need to locate the four wires on both the trailer and the towing vehicle.
Once you have located the wires, you will need to strip the ends of each wire so that they can be connected to the corresponding wire on the other end. You can use wire strippers or a knife to strip the ends of the wires.
Next, you will need to connect the wires using wire connectors or electrical tape. Make sure that each wire is securely connected to the corresponding wire on the other end.
Testing the Wiring
Once you have wired the trailer, it’s important to test the wiring to make sure everything is working correctly. To do this, you will need to connect the trailer to the towing vehicle and turn on the lights, turn signals, and brake lights.
If everything is working correctly, the lights on the trailer should light up and the turn signals and brake lights should function properly. If something isn’t working correctly, you may need to go back and double check your wiring connections.
Conclusion
Wiring a 4 wire trailer may seem intimidating at first, but it’s really quite simple once you understand the basics. By following the wiring diagram and taking your time to properly connect each wire, you can ensure that your trailer is safely and reliably connected to your towing vehicle.
