If you own a recreational vehicle or RV, you’ll know that it comes with a 7-pole electrical plug that connects to the vehicle’s electrical system. This plug allows you to power up your RV’s lighting, battery chargers, and other electrical components. But how do you wire a 7-pole RV plug correctly? In this guide, we’ll give you a complete wiring diagram, along with FAQs and tables to help you understand the process. So let’s get started!
Understanding the 7-Pole RV Plug Wiring Diagram
The 7-pole RV plug wiring diagram comprises seven different wires, each of which serves a specific function. Here they are:
| Wire Color | Function |
|---|---|
| White | Ground wire |
| Blue | Electric brake wire |
| Green | Tail lights wire |
| Black | Battery charge wire |
| Yellow | Left turn/brake wire |
| Red | Stop/brake wire |
| Brown | Right turn/brake wire |
It’s important to note that the wiring diagram may vary depending on the type of RV you have. So before you get started, make sure you have the correct wiring diagram for your RV.
How to Wire a 7-Pole RV Plug
Wiring a 7-pole RV plug is not as difficult as it may seem. All you need is a few tools and some basic knowledge of electrical wiring. Here’s how you do it:
Step 1: Cut the Wires
The first step is to cut the seven wires to the appropriate length. Make sure you leave enough room for connecting the wires to the plug later on. You want to make sure the wires are long enough to reach their respective connections inside the plug.
Step 2: Strip the Wires
The next step is to strip about 1/2 inch of insulation off each wire using a wire stripper. Be careful not to damage the wires while stripping them. You want to expose enough bare wire to create a solid connection.
Step 3: Connect the Wires to the Plug
Once you’ve stripped the wires, you can start connecting them to the plug. You’ll need to remove the plug’s cover and insert each wire into its respective connection point. Here’s how to connect each wire:
White Wire (Ground Wire)
The white wire is usually the longest and connects to the ground terminal. Make sure it’s securely connected and tightened down.
Blue Wire (Electric Brake Wire)
The blue wire connects to the electric brake controller, which is usually located near the brake pedal in the tow vehicle. Make sure you test the brakes after wiring up this wire to ensure they’re working correctly.
Green Wire (Tail Lights Wire)
The green wire connects to the tail lights on your RV. Make sure you test the lights afterward to ensure they’re working correctly.
Black Wire (Battery Charge Wire)
The black wire connects to your RV’s battery and charges it while you’re driving. Make sure you connect it to the battery terminal and not the negative terminal of your RV’s electrical system.
Yellow Wire (Left Turn/Brake Wire)
The yellow wire connects to the left turn signal and brake light. Make sure you test the lights afterward to ensure they’re working correctly.
Red Wire (Stop/Brake Wire)
The red wire connects to the stop and brake light. Make sure you test the lights afterward to ensure they’re working correctly.
Brown Wire (Right Turn/Brake Wire)
The brown wire connects to the right turn signal and brake light. Make sure you test the lights afterward to ensure they’re working correctly.
Step 4: Test the Connections
Once you’ve connected all the wires, it’s time to test the connections. Use a multimeter to check the voltage on each wire and make sure it’s at the correct level. If there’s a problem, you’ll need to troubleshoot the connection and fix any issues.
