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 Hyundai Tucson (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, Curt part number 55528 is designed for the Hyundai Tucson. The manual does not specify model year restrictions, so compatibility should be confirmed with the retailer or manufacturer if your vehicle is significantly older or newer than the manual publication date (02/18/09).
The kit includes a T-Connector with yellow and green wire ends, a black converter box, double-sided tape, cable ties, an eyelet, a screw, and a 4-flat connector. The manual does not specify quantities of cable ties or other consumables.
You will need a Phillips head screwdriver to remove the vehicle's taillight housing screws. If you do not have a suitable existing grounding point (screw with nut in the vehicle frame), you will need a drill with a 3/32" bit to create one.
Open the hatch and remove the two Phillips head screws from each taillight housing. Separate the vehicle's electrical connector from the back of the taillight housing. Repeat on both sides.
Route the T-Connector end with the yellow wire up through the opening under the driver's side taillight housing and insert it between the separated vehicle connector and the taillight housing connector.
Route the T-Connector end with the green wire along the back side of the bumper to the passenger side, then insert it between the separated connectors at the passenger side taillight housing, following the same procedure as the driver's side.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If none is available, drill a 3/32" hole and secure the white wire using the eyelet and screw provided in the kit.
Drilling is required only if a suitable existing grounding point (screw with nut in the vehicle frame) is not available near the connector. If you must drill, use a 3/32" bit and secure the white wire using the eyelet and screw provided.
Drill a 3/32" hole for the ground wire if an existing grounding point is not available. Secure the white wire using the eyelet and screw provided in the kit.
Adhere the black converter box to the frame of the vehicle using the double-sided tape provided in the kit. Choose a location that is secure and does not interfere with vehicle operation.
Secure any loose parts of the T-Connector with the cable ties provided in the kit to prevent movement and potential damage during vehicle operation.
Route the 4-flat connector to the center of the vehicle and secure it in a convenient location that is out of the way and does not interfere with vehicle operation or occupants.
Before drilling, verify that miscellaneous items are not hidden behind or under any surface where you plan to drill. This prevents damage to hidden components and personal injury.
