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 Nissan Sentra (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 56205 is designed for the Nissan Sentra. The T-Connector harness connects to the vehicle's taillight wiring harness connectors located in the trunk behind the taillights.
Yes, you must disconnect the negative battery terminal before beginning installation. The battery is located on the driver's side under the hood.
Open the trunk and remove all trunk floor coverings. Then remove the two plastic push fasteners on each side of the rear scuff panel, and pull the scuff panel out at the bottom and then up to remove it.
On the driver's side, pull back the felt trunk liner to locate the taillight wiring harness connectors. Separate the connector from the taillight housing carefully without damaging the locking tabs. Insert the T-Connector end with the yellow wire between the separated connectors, ensuring they are fully inserted with locking tabs in place. Repeat on the passenger side using the T-Connector end with the green wire.
Drilling may be required for the grounding point. If a suitable existing screw with nut is not available on the vehicle's frame near the connector, you will need to drill a 3/32" pilot hole for the provided screw. Before drilling, verify that no miscellaneous items are hidden behind or under any surface to avoid damage and personal injury.
Drill a 3/32" pilot hole for the provided grounding screw.
The T-Connector has two ends: one with a yellow wire that connects to the driver's side taillight wiring harness, and one with a green wire that connects to the passenger's side taillight wiring harness. There is also a white ground wire that connects to a grounding point on the vehicle's frame using the provided ring terminal and screw. The black power wire routes from the battery.
The battery connection must be fuse protected with a maximum of 10 amps. Exceeding this rating can cause loss of warranty, overheating, and potential fire.
Signal circuits are limited to 3.0 amps per side, and tail/running lights are limited to 6.0 amps total. Do not exceed the tow vehicle's lamp load rating or the product rating, whichever is lower. Check your vehicle owner's manual or contact the vehicle manufacturer for more information.
Locate a flat spot inside the trunk that is out of the way and adhere the black converter box using the double-sided tape provided.
Route the 4-flat wire to the center of the vehicle and secure it in a convenient, out-of-the-way location. Use the cable ties provided to secure any loose wires.
Reinstall all items removed during installation, including the trunk floor coverings, rear scuff panel, and felt trunk liner.
The kit includes a ring terminal and screw for grounding, double-sided tape for mounting the converter box, and cable ties for securing loose wires.
Disconnect the negative battery terminal on the driver's side under the hood. Open the trunk and remove all trunk floor coverings. Remove the two plastic push fasteners on each side of the rear scuff panel and remove the panel. Remove the plastic push fasteners holding the felt trunk liner in place on both sides.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If one is not available, drill a 3/32" pilot hole for the provided screw. Clean the ground area of any rust, dirt, or paint before securing the white ground wire using the ring terminal and screw provided.
