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 Toyota Grand Highlander, Lexus TX 350, TX 500h, and TX 500h+ (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 5,000 lbs. GTW and 500 lbs. TW. 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.
CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Toyota Highlander, Grand Highlander, Lexus TX350, TX550h, and TX55h+ (to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

The 13519 has a gross trailer weight (GTW) capacity of 5,000 lbs and a tongue weight (TW) capacity of 500 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
The kit includes 4 hex bolts (M12) and 4 conical-toothed washers (1/2"). These fasteners are used to secure the hitch to the vehicle frame weldnuts.
You will need: ratchet, flathead screwdriver, 19mm socket, safety glasses, and a torque wrench. A tools reference guide is available at curtmfg.com/trailer-hitch-installation.
Yes. Use a flathead screwdriver to remove the two plastic weldnut plugs on the outer side of the frame rail on both sides of the vehicle. Return the plugs to the vehicle owner after installation.
To remove debris from weldnuts in the frame, spray lubricant or compressed air into the hole. For heavy debris, use a wire brush. Take care not to damage the threads.
1. Remove the two plastic weldnut plugs from the frame rails using a flathead screwdriver. 2. Raise the hitch into position and align the mounting holes with the weldnuts in the frame. 3. Loosely install the hex bolts and conical-toothed washers. 4. Torque all hardware to 86 ft-lbs.
Yes. Loosely install the supplied hex bolts and conical-toothed washers first to align the hitch properly with the frame weldnuts. Only after alignment is complete should you torque all hardware to the final specification of 86 ft-lbs.
All hardware on the 13519 must be torqued to 86 ft-lbs.
The hitch uses four M12 hex bolts to secure it to the vehicle frame weldnuts.
The hitch uses four 1/2" conical-toothed washers. These washers must be oriented correctly under the bolt heads to ensure proper clamping force.
The conical-toothed washers must be installed with the toothed side facing the hitch side plate. The assembly diagram on page 2 shows the correct orientation: the washer sits between the hex bolt head and the hitch mounting surface.
Safety glasses must be worn at all times while installing this product. Additionally, never exceed your vehicle manufacturer's recommended towing capacity when using the hitch.
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. This helps prevent damage to the product and vehicle.
Part 56524 is designed for SUVs and Vans (S-series vehicles). The manual does not specify individual makes, models or model years. Contact Curt Manufacturing or consult a fitment database with your vehicle's year, make and model to confirm compatibility before purchase.
Part 56524 is a wiring harness that provides trailer lighting connections for SUVs and vans. It includes signal circuits rated at 5.0 amps per side and tail/running circuits rated at 7.5 amps total. The harness connects to a 4-flat trailer connector and includes a converter module with fuse protection.
You will need: a ratchet, a 10mm socket, a socket extension, a panel trim removal tool, and a cutting tool. A small flathead screwdriver is also required to remove the fastener trim cover. Proper tools will improve installation quality and reduce installation time.
The harness includes: a large white connector harness with black converter module, a fuse holder with fuse, a white ground wire with ring terminal, double-sided tape for mounting, a 4-flat connector for the trailer, and a dust cover for the jumper plug. The manual does not specify whether all fasteners and connectors are pre-assembled or require additional hardware.
The harness is located behind the driver-side rear access panel (location S3 on the wiring location guide). Specifically, you access it by opening the driver-side rear door, folding the second-row seat forward, and removing the third-row cup holder to reach the harness with the white connector just above where the cup holder was removed.
Open the driver-side rear door (second-row seats). Fold the second-row rear seat forward. Use a panel trim tool to remove the third-row seating cup holder. Just above the removed cup holder, remove the fastener trim cover with a small flathead screwdriver, then remove the 10mm fastener with a 10mm socket. Pull back the side trim just below the second-row seat belt. Separate the wall housing just below the glass. The harness with a white connector is located just above where the cup holder was removed.
Mount the converter module (part of the large white connector harness with black converter module) below the armrest using the provided double-sided tape. The grounding point is located just behind the seat belt strap, where you will secure the white ground wire using the ring terminal and the existing 10mm bolt.
Locate the grounding point just behind the seat belt strap. Remove the existing 10mm bolt. Secure the white ground wire to the bolt using the ring terminal, then reinstall the bolt. This provides the ground connection for the converter module.
The jumper plug is located at the driver-side rear of the bumper. Remove the dust cover and install the harness with the 4-flat connector to the jumper plug connector.
Route the 4-flat connector to the center of the vehicle next to the hitch and secure it in place with zip ties. This routing protects the connector and keeps it organized.
The battery connection must be fuse-protected with a maximum 15-amp fuse. The manual does not specify the exact fuse size required; contact Curt Manufacturing or consult your vehicle's electrical specifications to determine the correct fuse amperage for your application.
Signal circuits are rated at 5.0 amps per side. Tail and running circuits are rated at 7.5 amps total. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
The manual does not specify a maximum tow load. It states: do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Check your vehicle owner's manual or contact the vehicle manufacturer for your vehicle's lamp load rating and towing capacity.
Exceeding the product rating can cause loss of warranty, overheating and potential fire. The battery connection must be fuse-protected with a 15-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
After all installation steps are complete, attach the battery and test the harness using a test light, 4-flat tester, or a functioning trailer. This verifies that the harness is functioning properly before you reinstall all items removed during installation.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. The manual does not specify the inspection interval; consult your vehicle owner's manual or Curt Manufacturing for recommended maintenance schedules.
