All Hardware and Installation Instructions Included!
However you define adventure -- whether it's climbing onto the back of a mountain bike, hunting from the top of a tree stand or camping with the family a long way from nowhere -- CURT class 1 hitches provide a light-duty towing receiver to help you Bring It. Each is made to fit a specific vehicle, providing easier installation, a better fit and optimal towing capacity. Custom class 1 trailer hitches are available for a variety of smaller vehicle types, including the compact car, crossover, minivan and small SUV. This particular class 1 hitch is designed to be a custom hitch for certain years of the Lexus ES350 (to verify vehicle compatibility, see the CURT application guide at curtmfg.com). Tested in accordance with SAE J684, it offers a weight carrying capacity of 2,000 lbs. GTW and 200 lbs. TW. It is equipped with 1-1/4" receiver tube opening to accept a ball mount shank or other hitch mount. This class 1 hitch also comes with all necessary mounting hardware. With its lightweight design and smaller receiver tube size, a class 1 hitch is especially useful for adding cargo space with a hitch-mounted bike rack or cargo carrier. They can also typically be used to tow small trailers such as a utility trailer, kayak trailer or teardrop camper (never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Though CURT class 1 trailer hitches are only intended for light-duty towing, we apply the same principles of quality as we do to the rest of our rear mount hitches. Each class 1 hitch is made with hands-on engineering, high-strength steel and precise welding. We use a co-cured finish of liquid A-coat, inside and out, and durable black powder coat to provide a lasting defense against rust, chips and UV rays.
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 ES300h and ES350 (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.

Yes, CURT part number 11362 is designed for 2013-Present Lexus ES 350 and ES 300h sedans. The hitch is a weight-carrying type with a maximum trailer weight capacity of 2,000 lbs and tongue weight capacity of 200 lbs. Always verify your vehicle's manufacturer towing capacity before towing, as you must not exceed it.
The CURT 11362 is designed for use with ball mount D-55001 or 45501. A Euro mount option is also available with part numbers 45571 (1 7/8" ball) or 45572 (2" ball).
The CURT 11362 has a maximum trailer weight capacity of 2,000 lbs and a tongue weight capacity of 200 lbs. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
Required tools include: 10mm, 12mm, 14mm short and long, and 17mm sockets; ratchet; 6-inch extension; torque wrench; die grinder; aviator shears; masking tape; tape measure; screwdriver; and rubber isolator remover. Safety glasses must be worn at all times during installation.
Installation is rated as moderate difficulty. Two people may be required to ease installation. Professional installation takes approximately 60 minutes; novice DIY installation takes approximately 120 minutes. If you are hesitant to undertake this task, contact an authorized CURT installer or call technical support at 877-287-8634.
Two people may be required to ease installation. The manual does not specify that two people are mandatory, but recommends their use to improve the quality of the install and reduce installation time.
No drilling is required. However, a die grinder is required to enlarge the existing large holes in the frame rails on each side to allow the carriage bolts and spacers to pass through. The heat shield must be trimmed as required to allow bolts to pass through. On single exhaust models, the underbody panel must be trimmed for the hitch to pass through.
No, you do not need to remove the exhaust system. However, you must lower the exhaust by 6-10 inches by removing rubber isolators and hanger brackets. The exhaust is then raised back into location and rubber isolators are reinstalled after the hitch is secured.
Torque all 10mm fasteners to 56 lb-ft and all 7/16" fasteners to 70 lb-ft.
The kit includes: 2 carriage bolts (7/16-14 UNC, 1-1/4", Grade 8, part 10-10281); 2 serrated flange nuts (7/16-14 UNC, Grade 8, part 20-00103); 2 square hole spacers (0.250 x 0.88 x 2.25", part CM-SP2); and 2 pieces of 7/16" fishwire (part 7_16 FISHWIRE). Existing fasteners from removed brackets and rubber isolators are reused.
After enlarging the frame rail holes with a die grinder, reverse fishwire the supplied bolts and spacers into the enlarged holes on each side using the two fishwires provided. This technique allows you to thread the fasteners through the holes without removing the frame rail.
The hitch is rated for a maximum trailer weight of 2,000 lbs and tongue weight of 200 lbs. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower than these ratings.
Non-trailer loads (wheel-less loads) can be applied to this hitch, but they must be supported by CURT 18050 stabilizing straps. Failure to properly support non-trailer loads will void the product warranty. CURT recommends the use of 18050 stabilizing straps for all non-trailer loads.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify a retorque interval or other maintenance procedures beyond this periodic inspection.
Single exhaust models require removal of 5 isolators (instead of 7 for dual exhaust), removal of 3 push-button fasteners and 3 plastic nuts (instead of 2 and 2), and removal of 1 additional screw from the driver side frame rail. Single exhaust models also require trimming of the underbody panel for the hitch to pass through, as shown in the diagrams. Dual exhaust models do not require this trimming.
Yes, you must remove the heat shield(s) using a 10mm socket to access the frame rails. After enlarging the frame rail holes, the heat shield is trimmed as required to allow bolts to pass through, then clamped between the hitch and the vehicle frame during final installation.
The fasteners removed from the tie down/exhaust hanger brackets in step 3 are reused to attach the hitch to the vertical flange and frame rail. The rubber isolators removed from the exhaust are also kept and reinstalled after the hitch is secured.
Yes, CURT 11362 fits 2013-Present Lexus ES 350 and ES 300h sedans. Maximum capacity: 2,000 lbs trailer weight, 200 lbs tongue weight. Always verify your vehicle's manufacturer towing capacity.

No drilling required. Die grinder needed to enlarge existing frame rail holes. Heat shield trimming required. Single exhaust models require underbody panel trimming.
Torque all 10mm fasteners to 56 lb-ft and all 7/16" fasteners to 70 lb-ft.
Yes, but non-trailer loads must be supported by CURT 18050 stabilizing straps. Failure to use straps voids the warranty.
Professional installation: 60 minutes. Novice DIY installation: 120 minutes. Two people may be required to ease installation.
Periodically check that all fasteners are tight and all structural components are sound. No other maintenance procedures are specified in the manual.
Ensure the frame rail holes have been sufficiently enlarged with the die grinder to allow the carriage bolt and spacer to pass through. The holes must be large enough for the fasteners to be threaded through. If the holes are too small, use the die grinder to enlarge them further. If you continue to have difficulty, contact CURT technical support at 877-287-8634.
The heat shield should be trimmed as required to allow bolts to pass through. Trim additional material as needed to ensure the shield fits between the hitch and frame without interference. The shield should be clamped securely between the hitch and frame during final installation. If trimming does not resolve the issue, contact CURT technical support at 877-287-8634.
Ensure you have removed all required rubber isolators and hanger brackets. Remove 2 rubber isolators by each muffler, 1 hanger on the passenger side by the muffler, and 1-2 center isolators (leaving the isolator by the engine attached). The exhaust should lower 6-10 inches. If it does not lower sufficiently, verify all isolators and brackets have been removed and contact CURT technical support at 877-287-8634.
Periodically check the receiver hitch to ensure all fasteners are tight. Retorque all 10mm fasteners to 56 lb-ft and all 7/16" fasteners to 70 lb-ft. The manual does not specify a retorque interval, but regular inspection and tightening as needed will maintain hitch integrity.
The CURT 56430 is a powered converter lead wiring harness designed to provide trailer lighting functions on passenger cars. It connects to the vehicle's taillight wiring and includes a converter box that processes signals for left turn (yellow wire), right turn (green wire), brake (red wire), and taillight (brown wire) functions. The system requires a 12-volt negative ground electrical system and includes a 4-flat connector for trailer attachment.
The CURT 56430 is designed for passenger cars with rear taillights accessible from inside the trunk. The manual shows wiring locations P3 and P4 (behind driver and passenger side taillight housings inside the trunk) as the primary connection points. Verify your vehicle has accessible taillight connectors in the trunk before purchasing. Consult the vehicle owner's manual or contact CURT for specific vehicle compatibility.
Yes. The CURT 56430 is designed exclusively for 12-volt negative ground electrical systems. Do not use this converter on any other system type. Verify your vehicle uses a 12-volt negative ground system before installation.
Required tools are: ratchet, 10mm socket, socket extension, cutting tool, wire crimper, wire stripper, panel trim removal tool, and electrical tape. These tools are needed to remove fasteners, disconnect battery, remove trunk panels, separate connectors, and prepare and secure wiring.
The kit includes: a custom wiring harness with yellow wire (driver side) and green wire (passenger side), a black converter box, a black power wire (12 GA), a white ground wire with ring terminal, a 4-flat connector with dust cover, cable ties, double-sided tape for mounting the converter box, a screw for the ground wire ring terminal, and a fuse holder with 10-amp fuse.
Yes. You must disconnect the negative battery terminal before wiring the power wire. Locate the battery using your vehicle owner's manual, disconnect the negative terminal, and fasten this wire down and away from the battery. Reconnect the negative terminal only after all other installation steps are complete and the harness has been tested.
Remove the following in order: (1) floor coverings, (2) two cargo tie-downs from the trunk scuff panel using a 10mm socket, (3) three push fasteners from the rear scuff panel using a panel trim removal tool, then remove the scuff panel by pulling out at the bottom then up, (4) two push fasteners securing the trunk liner on the driver side using the panel trim removal tool, and (5) the cargo hook by pressing in on the two tabs and pulling away. Repeat steps 4–5 on the passenger side.
Starting on the driver side, pull back the trunk liner to locate the vehicle taillight wiring connectors. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wire harness end with the yellow wire between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place. Repeat on the passenger side with the green wire harness end.
Locate a flat spot inside the vehicle near the taillight (on the driver side). Adhere the black converter box using the provided double-sided tape. Ensure the surface is clean and flat to allow the tape to bond properly.
Locate a suitable grounding point between the driver-side taillight wiring and the trunk opening. Use a 10mm socket to remove the existing grounding bolt. Clean the area of rust, dirt, and paint. Secure the white ground wire using the ring terminal and the provided screw. Ensure all items originally attached to this ground point remain attached, as removing them will cause electrical components to malfunction.
Route the 12 GA black power wire from the vehicle battery to the converter, taking care to avoid pinch points and hot or rotating components. When passing the power wire through sheet metal, use an existing grommet, add a new grommet, or apply silicone to protect the wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties.
Route the 12 GA black power wire to the positive (+) battery terminal. Use a ring terminal for the battery connection. Do not connect the power wire until all other installation steps are complete. After all connections are made and tested, install the 10-amp fuse in the fuse holder as the final step.
Drilling may be required. The white ground wire uses a ring terminal that attaches to the vehicle body with a provided screw. If no existing hole is available at the grounding point, drill a 3/32" hole. Before drilling, check for miscellaneous items that may be behind or under the surface to avoid personal injury or property damage.
Signal circuits (left and right turn): 3.0 amps per side. Tail/Running circuits: 6.0 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding the rating can cause loss of warranty, overheating, and potential fire.
A 10-amp maximum fuse is required. The battery connection must be fuse-protected with a 10-amp fuse. Install the fuse in the provided fuse holder after all other installation steps are complete. Do not exceed this rating, as it can cause loss of warranty, overheating, and potential fire.
Yellow wire: left turn signal. Green wire: right turn signal. Red wire: brake signal. Brown wire: taillight/running light. The yellow and green harness ends connect to the driver and passenger side taillight connectors respectively. The red brake wire must be grounded if the converter is used as a powered module for a two-wire system.
The 4-flat connector is the trailer attachment point. 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. A dust cover is provided to help prevent corrosion. Secure any loose wires with the provided cable ties.
The manual does not specify a tow rating for the CURT 56430. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Consult your vehicle owner's manual or contact CURT for the specific tow capacity of your vehicle and this product.
After connecting the 12-volt power wire to the harness, verify that the harness is functioning by attaching the battery and testing with a test light, 4-flat tester, or a functioning trailer. Do not install the fuse until all other steps are complete and testing is successful. Once tested, reinstall all items removed during installation, reconnect the negative battery terminal if it was disconnected, and install the provided 4-flat dust cover.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. Check that the converter box remains securely adhered and that all cable ties are intact. Verify that the 4-flat connector dust cover is in place when not in use to prevent corrosion.
The CURT 56430 is designed for passenger cars with rear taillights accessible from inside the trunk. It requires a 12-volt negative ground electrical system. Verify your vehicle has accessible taillight connectors at locations P3 and P4 (behind driver and passenger side taillight housings inside trunk) before purchasing.
You need: ratchet, 10mm socket, socket extension, cutting tool, wire crimper, wire stripper, panel trim removal tool, and electrical tape. All other components including hardware, tape, cable ties, and fuse are included.
Yes. Disconnect the negative battery terminal before wiring the power wire. Reconnect it only after all installation steps are complete and the system has been tested.
Drilling may be required only for the ground wire attachment. If no existing hole is available at the grounding point, drill a 3/32" hole. Check for items behind the surface before drilling to avoid injury or damage.
A 10-amp maximum fuse is required. The battery connection must be fuse-protected. Do not exceed this rating, as it can cause loss of warranty, overheating, and potential fire.
Yellow = left turn, Green = right turn, Red = brake, Brown = taillight. The yellow and green harness ends connect to driver and passenger side taillight connectors. The black power wire connects to the positive battery terminal.
Verify that all items originally attached to the grounding point (between the driver-side taillight wiring and trunk opening) remain attached after installation. If any items were removed or disconnected during the grounding process, they must be reattached. Loose or missing connections at the grounding point will cause electrical components to malfunction. Inspect the grounding bolt and ring terminal to ensure they are secure.
1. Verify the negative battery terminal is connected. 2. Check that the 10-amp fuse is installed in the fuse holder and is not blown. 3. Confirm the black power wire is securely connected to the positive (+) battery terminal with a ring terminal. 4. Verify the white ground wire ring terminal is securely attached to the grounding point and the area is clean of rust and paint. 5. Ensure the yellow and green harness connectors are fully inserted into the vehicle taillight connectors with locking tabs engaged. 6. Test with a test light, 4-flat tester, or functioning trailer to identify which circuit is not working. 7. Inspect all wires for visible damage or loose connections.
