As a trailer owner, you know that having a reliable and properly functioning electrical system is an essential part of safe and successful towing. One of the most important components of this system is the 7 pole connector, which provides power and communication between your towing vehicle and trailer. In this article, we’ll take a close look at the 7 pole connector wiring diagram, including the various connections, colors, and functions.
What is a 7 Pole Connector?
The 7 pole connector, also known as a seven-way connector or RV trailer plug, is a standard electrical connection used in most modern trailers. It consists of seven pins or blades that connect to various electrical components and systems on the trailer. These connectors are typically found on larger trailers, such as RVs, horse trailers, and cargo trailers, and are often used for both lights and brakes.
Before we dive into the wiring diagram, let’s take a look at the different pins and their corresponding functions:
| Pin # | Function |
|---|---|
| 1 | Left turn and brake lights |
| 2 | Reverse lights |
| 3 | Ground |
| 4 | Right turn and brake lights |
| 5 | Electric brake controller |
| 6 | Auxiliary or backup power |
| 7 | 12-volt power |
