If you own an RV, chances are you’re familiar with the 7 way wiring diagram. This important diagram helps you understand how your RV’s electrical system works and how to troubleshoot any problems that may arise.
What is a 7 Way Wiring Diagram?
A 7 way wiring diagram is a diagram that illustrates the connections between the RV’s electrical system and the tow vehicle’s electrical system. It shows how the different wires connect and what they are responsible for.
There are several different types of connectors that can be used for the 7 way wiring diagram, but the most common is the round connector. This connector has 7 pins, each of which serves a specific purpose.
What are the Different Pins?
The pins on a 7 way connector are numbered and color-coded. Here’s what each pin is responsible for:
| Pin Number | Color Code | Function |
|---|---|---|
| 1 | White | Ground |
| 2 | Blue | Electric Brakes |
| 3 | Green | Tail, License, and Running Lights |
| 4 | Black | Battery Charge |
| 5 | Red | Left Turn/Brake Lights |
| 6 | Brown | Right Turn/Brake Lights |
| 7 | Yellow | Auxiliary (Backup) Lights |
How to Use the Wiring Diagram
Understanding the 7 way wiring diagram can be a bit overwhelming at first, but it’s actually quite simple. Once you know what each pin is responsible for, you can easily troubleshoot any problems you may have.
For example, if you’re having trouble with your electric brakes, you’ll want to check the blue wire (pin 2) to make sure it’s getting the proper voltage. If you’re having trouble with your turn signals, you’ll want to check the red (left) and brown (right) wires (pins 5 and 6) to make sure they’re getting the proper voltage.
