Why I Had to Wire 4 Pin Trailer Lights to 7
I recently purchased a new trailer and realized that it had a 4 pin wiring connector, while my truck had a 7 pin connector. This left me in a bit of a predicament as I couldn’t simply plug in my trailer and hit the road. After doing some research and consulting with friends who are more experienced with trailers, I learned that I needed to wire my 4 pin trailer lights to the 7 pin connector on my truck. Here are some reasons why this was necessary:
1. Compatibility: The primary reason for wiring the trailer lights to the 7 pin connector is compatibility. While most newer vehicles come equipped with a 7 pin connector, older models or smaller trucks may only have a 4 pin connector. By wiring the lights to the 7 pin, it allows for compatibility between different types of vehicles and trailers.
2. Additional Functions: The 7 pin connector offers additional functions that may not be available with a 4 pin connector. These include features such as electric brakes, reverse lights, and battery charging capabilities. By wiring the lights to the 7 pin, these additional functions can be utilized if
My Buying Guide on ‘Wire 4 Pin Trailer Light To 7’
I recently purchased a new trailer and realized that it had a 4 pin wiring system instead of the standard 7 pin. This meant that I couldn’t use my trailer lights and had to find a way to convert it. After doing some research and trial and error, I was able to successfully wire my 4 pin trailer light to a 7 pin connection. Here is my buying guide on how to make this conversion.
1. Know the difference between 4 pin and 7 pin wiring systems
The first step in converting your trailer’s wiring system is understanding the difference between a 4 pin and a 7 pin connection. A 4 pin system has four wires which are used for basic lighting functions like brake lights, turn signals, and tail lights. On the other hand, a 7 pin system has seven wires which include additional functions like reverse lights, electric brakes, and auxiliary power.
2. Check your vehicle’s wiring system
Before purchasing any equipment or materials, make sure to check your vehicle’s wiring system. Some vehicles may already have a factory-installed converter that allows for both types of connections. If this is the case, then you won’t need any additional equipment.
3. Purchase a converter
If your vehicle does not have a built-in converter, then you will need to purchase one. A converter will take the four wires from your trailer’s wiring system and convert them into seven wires that can be connected to your vehicle’s wiring system.
4. Gather necessary tools and materials
In addition to purchasing a converter, you will also need some tools and materials to complete the conversion process. These may include wire strippers, wire connectors, electrical tape, zip ties, and possibly extra wire depending on the distance between your vehicle’s connection point and your trailers light assembly.
5. Follow instructions carefully
When installing the converter, make sure to follow the instructions provided by the manufacturer carefully. Each converter may have slightly different installation procedures depending on the brand or model.
6. Test before hitting the road
After completing the installation process, it is important to test your new connection before hitting the road with your trailer attached. Make sure all lights are functioning properly before heading out on your trip.
7. Consider professional installation
If you are not confident in your abilities or do not have experience with electrical work, it may be best to seek professional installation services for this conversion process.
In conclusion,
The process of converting a 4 pin trailer light to a 7 pin connection may seem daunting at first but with proper research and following these steps carefully, it can be easily accomplished. Remember to always prioritize safety when working with electrical connections and consider seeking professional help if needed.
