All Hardware and Installation Instructions Included!
Whatever your task at hand -- whether it's launching that boat before daybreak, setting up your camper before the rush or getting a final load to the dump before close -- CURT class 3 trailer hitches offer the strength needed for serious towing. They make it easy to hitch up and Bring It, offering a vehicle-specific fit and the weight capacity to handle a variety of trailers. Custom class 3 hitches are the most common type of receiver hitch for pickup trucks and SUVs. Because of their weight range, they are also found on full-size cars, crossovers and minivans. Each custom-fit class 3 hitch package is made for vehicle-specific mounting. This particular kit fits certain years of the Nissan Frontier (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 5,000 lbs. GTW and 500 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 6,000 lbs. WD and 600 lbs. WDTW. CURT class 3 trailer hitches are typically used to attach and haul utility trailers, boat trailers, campers, snowmobile or ATV haulers and more (NOTE: Never exceed the lowest-rated towing component). Each class 3 hitch has a 2" receiver tube and is tested in accordance with SAE J684 for safety. To ensure that CURT class 3 receiver hitches have what it takes for serious trailering, they are designed using a hands-on approach and are constructed with rugged, high-strength steel and precise welding. We also protect our class 3 hitches in a co-cured finish of liquid A-coat and black powder coat for superior resistance to rust, chipping and UV damage.
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 Frontier, Nissan Quest and Mercury Villager (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 manual lists two capacity ratings but the specific weight limits are blank: when used as a weight-carrying hitch, the trailer weight and tongue weight limits are not specified; when used as a weight-distribution hitch, the limits are also not specified. The manual emphasizes: 'DO NOT EXCEED VEHICLE MANUFACTURER'S RECOMMENDED TOWING CAPACITY.' Check your vehicle's owner manual or contact Curt Manufacturing for the exact capacity ratings for your 2000–04 Nissan Frontier 2DR.
1. Raise the hitch into position at the end of the vehicle frame. 2. Install fasteners as shown (the manual references a diagram not provided in this text). 3. Torque all 1/2-inch fasteners to 110 lb.-ft. The hitch uses existing frame rail holes; no drilling is required.
After installation, ensure all fasteners are tight and all structural components are sound. The manual states: 'PERIODICALLY CHECK THIS RECEIVER HITCH TO ENSURE THAT ALL FASTENERS ARE TIGHT AND THAT ALL STRUCTURAL COMPONENTS ARE SOUND.' Perform these checks regularly during ownership.
The manual recommends periodic checks to ensure all fasteners are tight and all structural components are sound, but does not specify a frequency. Establish a regular maintenance schedule, such as before each towing trip or monthly if the hitch is in regular use.
Do not exceed your vehicle manufacturer's recommended towing capacity. The Curt 13831 manual emphasizes this requirement but does not list the specific limit. Refer to your Nissan Frontier owner's manual or contact Nissan for your vehicle's maximum towing capacity.

The CURT 56423 is a powered converter lead that converts your vehicle's taillight wiring to a 4-flat trailer connector. It allows you to connect a trailer with standard 4-flat wiring to vehicles with factory taillight harness connectors. The converter is powered by the vehicle battery and includes a fuse-protected power circuit.
The CURT 56423 is designed for 12-volt negative ground vehicles with taillight wiring harness connectors. It is compatible with trucks (wiring location T4, behind center of rear bumper fascia) and SUVs/vans (wiring location S6, behind center of rear bumper). The manual states that battery location may differ depending on the vehicle, so you should verify your vehicle has accessible taillight connectors before purchasing.
You need a cutting tool. The manual also indicates that you may need to drill a 3/32" pilot hole for the ground screw if a suitable existing screw with nut is not available on the vehicle frame. A drill capable of making a 3/32" hole is recommended.
The kit includes: a custom wiring harness with connectors, a black converter box, double-sided tape for mounting the converter, a white ground wire with ring terminal and screw, cable ties for securing loose wires, a 4-flat dust cover, and a 10-amp fuse holder with fuse. The manual also references a 12 GA power wire and butt connectors for battery connection.
Yes. The manual explicitly states: 'Disconnect negative battery (-) cable before wiring the power wire.' This is a required safety step before beginning the installation.
The manual states that the vehicle taillight wiring harness connectors are located 'under the vehicle behind the spare tire,' but does not explicitly state whether the spare tire must be removed. You should check your vehicle's configuration to determine if removal is necessary to access the connectors.
Follow these steps in order: 1) Locate the vehicle taillight wiring harness connectors under the vehicle behind the spare tire and separate them from the taillight housing. 2) Insert the custom wiring harness between the separated connectors, ensuring they are fully inserted with locking tabs in place. 3) Locate a suitable grounding point near the connector and secure the white ground wire using the ring terminal and provided screw (drill a 3/32" pilot hole if necessary). 4) Adhere the black converter box to a flat spot near the vehicle factory plug using the provided double-sided tape. 5) Route the 4-flat to the center of the vehicle near the hitch and secure loose wires with cable ties. 6) Reconnect the negative battery terminal and install the 4-flat dust cover.
Route a 12 GA wire or larger from the converter to the vehicle battery location, taking care to avoid pinch points and hot or rotating components. Use an existing grommet, add a grommet, or use silicone to protect the power wire from sharp edges when passing through sheet metal. Attach the ring terminal of the power wire to the positive (+) battery terminal. Secure the power wire to the vehicle chassis using the provided cable ties. Install the 10-amp fuse holder with fuse after all other steps are complete.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. The area should be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and the provided screw. If no suitable existing screw is available, drill a 3/32" pilot hole and use the provided screw to secure the ground wire to the vehicle body.
Locate a flat spot near the vehicle factory plug. Adhere the black converter box using the provided double-sided tape. Ensure the surface is clean and dry for proper adhesion.
Route the 4-flat to the center of the vehicle near the hitch. Secure any loose wires with the provided cable ties to prevent movement and potential damage.
Drilling is not always required. If a suitable existing screw with nut is available on the vehicle frame near the connector, you can use that for grounding. If no suitable existing screw is available, you will need to drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for miscellaneous items that may be behind or under any surface to avoid personal injury or property damage.
Drill a 3/32" pilot hole for the provided ground screw if a suitable existing screw with nut is not available on the vehicle frame.
Signal circuits: 3.0 amps per side. Tail/Running circuits: 6.0 amps total. The battery connection must be fuse-protected with a 10-amp max fuse. Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower.
Use a 10-amp fuse maximum. The manual states: 'The battery connection must be fuse-protected, 10-amp max.' Install the fuse after all other installation steps are complete.
Use 12 GA wire or larger for the power connection from the converter to the vehicle battery.
The converter uses the following wire colors: Green for right turn signal, Red for brake, Yellow for left turn signal, and Brown for taillight. The white ground wire is used for grounding to the vehicle body. The black power wire connects to the positive battery terminal.
No. The manual explicitly states: 'This converter system is to be used only on 12 volt negative ground systems.' It is not compatible with positive ground systems.
If using the converter as a powered module for a two-wire system, the red brake wire must be grounded.
When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the power wire from sharp edges.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. The battery connection must be fuse-protected, 10-amp max. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
Before drilling, check for miscellaneous items that may be behind or under any surface to avoid personal injury or property damage.
Route the 12 GA power wire to the vehicle battery location, taking care to avoid any pinch points and hot or rotating components. Secure the power wire to the vehicle chassis using the provided cable ties.
After installation, reinstall all items removed during installation. If the negative battery terminal was disconnected, reconnect it. Install the provided 4-flat dust cover to help prevent corrosion. Test for proper function by using a test light or connecting a properly wired trailer.
Test for proper function by using a test light or connecting a properly wired trailer. This will verify that all wiring connections are correct and the converter is functioning properly.
