Keeping trailer lights and brakes connected is critical, and this harness makes it easy. The EZ Connector Custom Vehicle Wiring Harness w/ Magnetic 7-Way Trailer Connector uses a magnetic plug that locks together securely every time. You get a clean, firm connection that stays put through bumps and weather, so your trailer signals stay active when you need them most.
When you’re adding electric brakes, backup lights, or a charge line to your trailer, this 7-contact plug gives you everything in one setup. It works as a vehicle-end connector with both power and signal paths ready to go. The plug-and-lead design keeps wiring simple and lets you route the harness where it fits best.

If your vehicle didn’t come with a tow package, this harness fills the gap. It connects directly where a standard 7-way would mount near the bumper, giving you trailer lighting, brake, and auxiliary power without depending on factory wiring. That means you can tow safely even with a base model setup.
This harness is built as a plug-in system with no converter inline, giving you a straightforward, durable connection that doesn’t rely on extra modules. It’s made to handle the current from standard trailer circuits while keeping contacts protected from corrosion and vibration over time.

I am sorry to hear that you are having difficulty with this harness. I do see that this item may require additional components in order to operate. I see that this is also intended to be used with the part # 319-R7-07 trailer side plug. I have sent this information over to our customer service department for them to get in touch with you in hopes to get this corrected.
