Whatever the next checkpoint is on your adventure -- whether it's getting your bike on the trail before sunrise or making it to the campground before dark -- CURT class 2 hitches let you Bring It with confidence. These receiver hitches are made to handle most light-duty towing applications and offer a custom fit for your vehicle. Typically used on full-size cars, crossovers, compact SUVs, minivans or even compact pickup trucks, a CURT class 2 trailer hitch complements the design of smaller vehicles. This particular class 2 hitch is made to be a custom hitch for certain years of the Lexus NX200t and NX300h (to verify vehicle compatibility, see application info). It offers a weight carrying capacity of 3,500 lbs. GTW and 350 lbs. TW. Class 2 trailer hitches can typically be used to tow a variety of lightweight trailers, such as a small utility trailer, small fishing boat trailer or popup camper (NOTE: Never exceed the lowest weight capacity of any towing component). They are also perfect for adding cargo space to your vehicle with a bike rack or cargo carrier. This class 2 hitch features a 1-1/4" receiver tube to accept a ball mount shank or other hitch-mounted accessory. For safety, it is tested in accordance with SAE J684. A custom trailer hitch design requires extra care, and as such, CURT class 2 hitches are engineered using real vehicles and hands-on research. We use high-strength steel, robotic welding and rigorous testing to produce hitches that are built to fit your lifestyle. To ensure that each hitch will be a reliable extension of your vehicle, we also finish our hitches in a co-curing of liquid A-coat and black powder coat, giving them long-lasting rust and wear resistance.
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 Lexus NX200t and NX300h (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 signal circuits are rated at 3.0 amps per side, and the tail/running circuits are rated at 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
You will need: ratchet, 10mm socket, Phillips screwdriver, flat blade screwdriver, panel trim removal tool, wire stripper, wire crimper, and cutting tool. A drill may be needed if a suitable existing grounding point is not available.
Yes. The first step of installation is to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal. This must be done before any other work.
You must remove: all trunk floor coverings, fasteners securing the trunk storage trays, all storage trays, the spare tire cover, and the spare tire. You will also need to remove the scuff panel and cargo tie downs from the side trim panels.
The custom wiring harness end with the yellow wire connects on the driver side. It is inserted between the separated taillight housing connectors, behind the removed side trim panel. Make sure the connectors are fully inserted with locking tabs in place.
The custom wiring harness end with the green wire connects on the passenger side. It is routed behind the removed scuff panel and inserted between the separated taillight housing connectors, following the same procedure as the driver side (steps 4–6).
Drilling may be required for the ground wire. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, you may drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint. Always check for hidden items before drilling to avoid damage and personal injury.
Drill a 3/32" pilot hole if a suitable existing grounding point is not available. The area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
The black converter box should be adhered to a flat spot inside the vehicle near the taillight using the provided double-sided tape.
The battery connection must be fuse-protected with a 10-amp maximum fuse. 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.
When in use, route the 4-flat to the center of the vehicle. When not in use, roll it up and store in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties. Install the provided 4-flat dust cover to help prevent corrosion.
All steps must be followed to ensure the wiring harness functions properly. Once installed, test for proper function by using a test light or connecting a properly wired trailer. Reconnect the negative battery terminal and reinstall all items removed during installation before testing.
When removing the scuff panel, pull out on the bottom and then up. Take care not to damage the alignment tabs located on the back of the panel.
When separating the taillight housing connectors, take care not to damage the locking tabs. The custom wiring harness connectors will be similar to the vehicle's taillight connectors.
