Most trailer wiring kits need connectors on both sides of the car, but this one keeps it easy. The Curt T-Connector taps into the main tail light wiring on one side only, since that’s where the factory harness runs. It’s a cleaner setup with fewer steps and less panel removal during the install.
Instead of splicing wires or chasing down circuits, this harness plugs straight into the existing tail light connector. The factory-style plugs snap in place to give you a secure link for your trailer lights without damaging your vehicle wiring.
With its 4-flat end, the harness provides all the basics—running lights, turn signals, and brake lights—for most small trailers. It’s a simple, reliable connection that works with standard trailer wiring so you can hook up and go.
The harness stays tucked out of sight once installed, keeping things neat behind panels and trim. You get a hidden finish that looks like it came from the factory while still having easy access to the 4-flat plug when it’s time to tow.
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're going to be taking a look at part number C56046. This is the Curt T-Connector Vehicle Wiring Harness with your 4-Pole Flat Trailer Connector. This is going to fit certain years and models of the Chevrolet Impala. It's going to provide your 4-way flat trailer connector at the back of vehicle to power your trailer's signal lights. This is compatible with 5-pole, 6-pole, and 7-pole adapters. Adapters are sold separately. It's going to come with a dust cap for the 4-way flat connector.
That way you can cover up those connection points when the plug is not being used. The main benefit of this system is not only the 4-way flat connector, but it's designed to connect quickly and easily. You don't have to cut or splice any wires. All you have to do is locate the connection points behind the passenger side tail light and plug in your T-connector. This is vehicle specific.
This is designed to match up perfectly with the connectors on your vehicle. You are going to plug them. They're going to snap-lock together for a nice, tight, secure fit. Once you have that connected, you'll need to make your ground connection. It's going to be a white wire with a ring terminal attached to it. You can make that ground connection to a nice, clean metal surface with the included self-tapping screw that's provided in the hardware kit.
Then you can go ahead and secure your excess wires with the included zip ties. Then once your installation is complete, the 4-way connector is going to be stowed in an out-of-the-way location within your rear cargo area when it's not being used. That's going to come with your detailed instructions. These are going to walk you through the installation process step-by-step. We recommend that you use a small amount of dielectric grease on all your electrical connections like the plugs on the vehicle and the 4-pole connector itself. That's going to help prevent corrosion.
If you don't have some of that, you can find that here at etrailer.com. It is sold separately. That's going to do it for today's look at part number C56046.

After all this time, I give it a 5* still. The electrical connections are good, works the way it should. I haul my trailer about 230mi each way and have made many trips with the hook up and works great
