If you’re looking to get 12V power from your trailer plug, you’re in the right place. Whether you need to power a camping fridge, charge your phone, or connect any other 12V device, tapping into the power source of your trailer plug can be a convenient solution. In this guide, we’ll walk you through the steps on how to do it safely and efficiently.
Understanding the Trailer Plug
Before we dive into the process, let’s take a moment to understand the trailer plug. The 7-pin trailer plug, also known as the RV-style plug, is commonly used for towing trailers and connecting various electrical accessories.
Within the 7-pin trailer plug, the primary power outputs are the 12V power, ground, left turn/brake lights, right turn/brake lights, tail lights, backup lights, and electric brakes. For our purpose of accessing 12V power, we’ll focus on the specific wire responsible for supplying this voltage.
Identifying the 12V Power Wire
The 12V power wire is typically color-coded and can vary depending on the manufacturer, so it’s important to confirm which wire corresponds to the 12V power before proceeding. You can use a multimeter or consult the wiring diagram of your trailer plug to identify the correct wire. In most cases, the 12V power wire is color-coded black.
Tapping into the 12V Power Wire
Once you’ve identified the 12V power wire, you can tap into it to extract the 12V power for your devices. Here’s how:
- Prepare the necessary tools: Make sure you have a wire stripper, electrical tape, and crimp connectors handy.
- Disconnect the power source: Before working with any electrical components, it’s crucial to disconnect the power source to prevent any accidents or short circuits. Disconnect the trailer from the tow vehicle and ensure that the battery is also disconnected.
- Locate the 12V power wire: Once the power source is disconnected, locate the 12V power wire inside the trailer plug connector.
- Strip the wire: Strip a small section of the insulation from the 12V power wire using the wire stripper.
- Connect your device: Depending on your requirements, you can use crimp connectors or soldering techniques to connect your device to the exposed section of the 12V power wire. Make sure the connection is secure.
- Insulate the connection: To ensure safety and prevent any short circuits, wrap the exposed section of the wire and the connection point with electrical tape or heat shrink tubing.
- Test the connection: After completing the connection, it’s essential to test if the 12V power is successfully reaching your device. Reconnect the power source and check if your device is receiving the desired voltage.
Always prioritize safety while working with electrical components. Ensure that all connections are secure, the wire insulation is intact, and any exposed wires or connections are insulated properly to avoid any hazards.
