Are you planning to tow a heavy trailer? Then, you need to have a reliable wiring system that can manage the electrical demands of your trailer. In this article, we’ll discuss the 7 blade wiring diagram trailer side that can help you achieve a smooth towing experience.
What is a 7 Blade Wiring?
A 7 blade wiring system is a standard wiring setup used for trailers that have various electrical components such as brakes, tail lights, turn signals, and backup lights. It is also known as the RV-style wiring system since it is commonly found on RVs and camper trailers.
A 7 blade wiring system has seven pins that correspond to different functions, making it a versatile and efficient wiring system for trailers. This wiring system can handle different types of loads and can provide power for the necessary electrical components of a trailer.
How Does the 7 Blade Wiring Work?
The 7 blade wiring system consists of seven pins that are connected to different electrical components of the trailer. The pins are arranged in a circular pattern, and each pin corresponds to a specific function. The following are the functions of each pin:
| Pin Number | Function |
|---|---|
| 1 | Ground |
| 2 | Backup lights |
| 3 | Tail Lights |
| 4 | Right Signal and Brake |
| 5 | Left Signal and Brake |
| 6 | Electric Brakes |
| 7 | 12-Volt Power |
The first pin is for the ground wire, which is connected to the metal frame of the trailer to provide a safe and stable electrical connection. The second pin is for the backup lights, which can help you when reversing the trailer. The third pin is for the tail lights, which are essential for nighttime driving.
The fourth and fifth pins are for the right and left signal and brake lights, respectively. These pins provide power to the turn signals and brake lights, allowing other drivers to know your intentions on the road. The sixth pin is for the electric brakes, which can help control the trailer’s speed when going downhill or stopping abruptly. Finally, the seventh pin is for 12-volt power, which can power up appliances and other electrical components of the trailer.

Step 2: Disconnect the Battery
For safety reasons, you need to disconnect the battery of your vehicle before starting the installation process. This can prevent electrical shocks and other hazards while working on the wiring system.
Step 3: Mount the Wiring Harness
You need to mount the wiring harness on your trailer, typically on the side of the trailer tongue. Make sure to secure the harness using zip ties or clamps to prevent it from getting damaged or disconnected while on the road.
Step 4: Connect the Wires to the Pins
Once the harness is mounted, you need to connect the wires to the pins of the 7 blade connector. Make sure to follow the wiring diagram to ensure the correct connection of wires to the corresponding pins.
Step 5: Test the Wiring System
After connecting the wires, you need to test the wiring system using a test light or multimeter to ensure everything is working correctly. Test each pin of the 7 blade connector to confirm that each wire is correctly connected to its corresponding pin.
Step 6: Seal the Connections
Once you have tested the wiring system, you need to seal the connections using electrical tape or heat shrink tubing. This can prevent moisture and other elements from damaging the electrical connections, ensuring the longevity of the wiring system.
