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 Altima, Maxima and 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.

The battery connection must be fuse-protected with a 10-amp maximum. Signal circuits are rated at 3.0 amps per side, and tail/running circuits are rated at 6.0 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
You will need a Phillips screwdriver, flat blade screwdriver, and panel trim removal tool. The manual also references an included CME-PCL-INS sheet for battery routing details.
Drilling may be required. If a suitable existing grounding point (such as a screw with nut in the vehicle frame) is not available near the connector, you will need to drill a 3/32" pilot hole for the provided ground screw. The area must be free of rust, dirt and paint before securing the white ground wire.

1. Remove the four plastic fasteners securing the rear scuff panel and felt trim liner. 2. Remove the scuff panel and partially remove the felt trunk liner to locate the vehicle taillight wiring harness connectors. 3. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. 4. Insert the custom wiring harness end with the yellow wire between the separated connectors. 5. Make sure the connectors are fully inserted with locking tabs in place. 6. Repeat this process on the passenger side using the harness end with the green wire.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Install the provided 4-flat dust cover to help prevent corrosion.
The battery connection must be fuse-protected with a 10-amp maximum. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
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 will function properly.
The 56022 uses yellow, green, white, and black wires. The yellow wire connects to the driver side taillight, the green wire to the passenger side taillight, the white wire is the ground connection, and the black wire is the power connection from the vehicle battery.
