Trailers that are used to transport large items such as boats, cars, or heavy equipment usually require a specific type of electrical connection to the towing vehicle. This electrical connection is called the 7 pin blade trailer wiring. This article will provide you with a detailed explanation of what this wiring is, how it works, and how to install it on your trailer.
What is 7 Pin Blade Trailer Wiring?
The 7 pin blade trailer wiring system is a connection that provides power to the electric brakes, back up lights, and turn signals of a trailer. It consists of a seven-pin connector that is mounted on the towing vehicle and a matching connector on the trailer.
The seven pin connector has a specific design with different colored wires that are used for different purposes. These colors are standard across different manufacturers, making it easy to identify and connect the right wire to the right pin.
The 7 Pin Blade Trailer Wiring Diagram
| Pin Number | Wire Color | Function |
|---|---|---|
| 1 | Black | Battery Charge |
| 2 | Blue | Electric Brakes |
| 3 | White | Ground |
| 4 | Green | Tail lights |
| 5 | Brown | Right Turn Signal |
| 6 | Yellow | Left Turn Signal |
| 7 | Red | Back up lights |
As you can see from the diagram, each pin of the connector has a specific function that is essential for the proper functioning of the trailer’s electrical system.
How Does 7 Pin Blade Trailer Wiring Work?
The 7 pin blade trailer wiring system works by providing power to the various electrical components of the trailer from the towing vehicle. When the towing vehicle’s lights are on, power flows through the connector and into the trailer’s electrical system, powering the trailer lights, electric brakes, and back up lights.
The wiring system also ensures that the trailer’s electric brakes are synchronized with the vehicle’s brakes, allowing for smoother stops and better handling when pulling a heavy load.
How to Install 7 Pin Blade Trailer Wiring on Your Trailer?
Installing 7 pin blade trailer wiring on your trailer is a simple process that can be completed in just a few steps.
Step 1: Gather Materials
You will need the following materials to complete the installation:
- 7 pin blade trailer wiring harness
- Wire stripper
- Crimping tool
- Electrical tape
Step 2: Prepare the Trailer
Before you begin wiring the trailer, you must first prepare it for the installation. This involves removing any existing wiring, if present, and ensuring that the trailer’s electrical system is clean and dry.
Step 3: Wire the Trailer
Once the trailer is prepared, you can begin wiring it by connecting the wires from the 7 pin blade trailer wiring harness to the trailer’s electrical system.
To do this, you will need to strip the ends of each wire using a wire stripper, crimp them to the corresponding wires of the trailer’s electrical system using a crimping tool, and wrap them with electrical tape to ensure a secure connection.
Step 4: Test the System
After wiring the trailer, you should test the system to ensure that it is working properly. This involves connecting the trailer to the towing vehicle and checking that all the lights, turn signals, and electric brakes are functioning as expected.
