Replacing the 7-Way Trailer Connector: A Step-by-Step Guide 'replacing 7 way trailer connector'

When your 7-pin trailer connector starts to malfunction, it can cause a range of issues with your brake controller and towing experience. In this guide, we'll walk you through how to replace the 7-way plug attached to the cord on your trailer or fifth wheel.

Before you begin, make sure you have all the necessary tools, including wire cutters, a box cutter, and a few other essentials. You can also consider investing in a decent Leatherman multitool to simplify the process.

Step 1: Remove Outer Shielding

Start by removing the outer shielding from the plug without damaging the inner wires. To do this, make a lengthwise slice along the cord using a box cutter, being careful not to cut into any of the seven wires inside. Then, make another slice around the cord about two inches from the exposed end, but don't cut all the way through.

Step 2: Tear Off Rubber Shielding

Use the box cutter to gently slice through the outer rubber shielding, taking care not to damage the inner wires. This will allow you to remove the rubber shield without cutting into any of the wires inside.

Step 3: Snip Inner Wires

Use wire cutters to snip through all the wires in the cord close to the plug. This will ensure that you have a clean and secure connection once you've replaced the plug.

Step 4: Choose a New Plug

For this example, we chose the Curt 7-Pole Connector because it uses flat blade pole terminal connectors instead of squeeze-type connectors that can bend over time. Make sure to choose a high-quality plug that will provide a reliable connection for your trailer cord.

Step 5: Install New Plug

Once you have your new plug, attach it to the cord and make sure everything is securely connected. This should solve any faulty wiring problems caused by loose connections in the old plug.

Replacing the 7-way trailer connector may seem like a daunting task, but with these step-by-step instructions, you can do it yourself and avoid the hassle of prying connectors together or dealing with bent and damaged terminals. Remember to always choose a high-quality plug and take your time when making the replacement to ensure a secure connection.
