If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Buick Verano (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

Yes, the Curt 56288 is designed for the Buick Verano passenger car. It is installed behind the driver and passenger side taillight housings inside the trunk.
The harness has a Signal Circuits rating of 3.0 amps per side and a Tail/Running Circuits rating of 6.0 amps total. Do not exceed these ratings or the tow vehicle lamp load rating, whichever is lower, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
You will need a panel trim removal tool, wire stripper, wire crimper, and cutting tool. You may also need a drill to create a 3/32" pilot hole for the ground screw if a suitable existing screw is not available.
Yes, you must disconnect the negative battery terminal before beginning installation. This is the first step in the installation process.
The custom wiring harness end with the yellow wire is inserted between the separated driver side taillight connectors inside the trunk. The connectors must be fully inserted with locking tabs in place.
The custom wiring harness end with the green wire is routed to the passenger side behind the removed scuff panels and inserted between the separated passenger side taillight connectors, following the same procedure as the driver side.
The white wire is the ground wire. It must be secured to a suitable grounding point near the connector using the provided ring terminal and screw. You can use an existing screw with nut in the vehicle frame, or drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint.
The black converter box should be adhered to a flat spot inside the vehicle near the taillight using the provided double-sided tape.
Drilling may be required. You need to locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing screw is available, you must drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location. When in use, route it to the center of the vehicle. Secure any loose wires with the provided cable ties.
Test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring harness functions properly.
Install the provided 4-flat dust cover to help prevent corrosion.
