Dodge Ram 7 Pin Trailer Wiring Diagram

By | February 20, 2023



Are you looking to install a 7 pin trailer wiring harness in your Dodge Ram? If so, this guide is here to help you do it right. We'll walk you through the process step-by-step to make sure you get everything connected correctly and safely.

First off, you'll need to gather the right tools and materials for the job. These include wire strippers, electrical tape, a crimping tool, pliers, and the 7 pin trailer wiring harness. If you don't already have these items, you can easily purchase them from your local hardware store.

Next, you'll need to locate the connection point in your Dodge Ram for the harness. This is usually located near the tailgate but may vary depending on the model. Once you've located the connection point, you'll need to remove the factory plug that's already installed. To do this, use the wire strippers to carefully expose the wires in the plug.

Once the plug is removed, you'll be ready to start attaching the 7 pin trailer wiring harness. Refer to your Dodge Ram's owner's manual or a 7 pin trailer wiring diagram to ensure you connect the wires correctly. Start by connecting the red wire to the battery terminal and the black wire to the ground terminal. Then, using the crimping tool, attach the remaining wires to their corresponding terminals. It's important to make sure you get the colors right, as incorrect wiring can lead to electrical problems.

Finally, once all the wires are connected, use the electrical tape to secure them in place. Make sure to give each connection a few wraps of tape to make sure the wires are securely connected. Once this is done, you can go ahead and test the connection by plugging in a trailer to see if the lights and other features work properly.

There you have it! Installing a 7 pin trailer wiring harness in your Dodge Ram is a fairly simple process as long as you have the right tools and follow the instructions. Just remember to double-check your connections and use electrical tape to secure the wires in place. Good luck with your project!
