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 Versa (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.

A ring terminal must be used for the battery connection. The ring terminal of the white ground wire should be attached to the vehicle body using the screw provided.
The converter should be mounted using the double-sided tape provided with the kit.
A 3/32 inch hole should be drilled if necessary to attach the ring terminal of the white ground wire to the vehicle body. Drilling is only required if a suitable existing hole is not available.
Route the 12 GA wire from the converter to the vehicle battery location, taking care to avoid pinch points and hot or rotating components. The black wire connects to the positive battery terminal. Secure the power wire to the vehicle chassis using the cable ties provided.
When passing the power wire through sheet metal, use an existing grommet, add a new grommet, or apply silicone to protect the power wire from sharp edges.
The converter has four output wires: Green for right turn signal, Red for brake, Yellow for left turn signal, and Brown for taillight. If using the converter as a powered module for a two-wire system, the red brake wire must be grounded.
Before drilling, check for miscellaneous items that may be behind or under any surface to avoid personal injury or property damage.
The fuse should be installed after all other installation steps are complete. This is the final step in the installation process.
