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 Acura RDX (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 3,500 lbs. GTW and 350 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 Acura RDX (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.

Yes, CURT part 13423 is designed for the Acura RDX. However, the manual does not specify which model years are compatible. Contact CURT technical support at 1-877-287-8634 or visit www.curtmfg.com to confirm your specific year and trim level.
The manual notes that the hitch may interfere with the functionality of the liftgate sensor. If your vehicle has a power liftgate or liftgate sensor, test the liftgate operation after installation to confirm it functions correctly. If interference occurs, contact CURT technical support at 1-877-287-8634.
The hitch includes 4 M12×1.25 hex cap screws (HHCS), class 8.8, zinc-plated (part 10-10529) and 4 S-CON washers, 1/2 inch, zinc-plated (part 30-00149). All fasteners are torqued to 60 ft-lbs during installation. The hitch mounts to existing weld nuts on both frame rails.
You will need: ratchet, 19mm socket, exhaust removal pliers, torque wrench, 6-inch socket extension, prybar, and safety glasses. A torque wrench is essential to achieve the required 60 ft-lbs torque specification on all M12 fasteners.
Yes. Step 1 requires you to lower the spare tire using the vehicle's lowering tools and mechanism before installing the hitch. Consult your Acura RDX owner manual for the specific procedure. The spare tire is reinstalled in its original position after the hitch is secured.
Yes. Step 2 requires you to lower the exhaust by removing the two rearmost rubber exhaust isolators from the frame-mounted hangers. Support the exhaust to prevent damage during this process. The exhaust is reinstalled in its original position after the hitch is secured.
No. The CURT 13423 requires no drilling. The hitch mounts directly to existing weld nuts on both the driver and passenger frame rails.
All M12 fasteners must be torqued to 60 ft-lbs. Use a calibrated torque wrench to achieve this specification. This is performed in step 4 of the installation process.
Periodically check the hitch to ensure that all fasteners remain tight and that all structural components are sound. The manual does not specify a retorque interval, but regular inspection is recommended, especially after the first few towing cycles.
Do not exceed your vehicle manufacturer's recommended towing capacity. The CURT 13423 has a specified gross load capacity, but your Acura RDX's factory towing limit is the controlling factor. Consult your vehicle owner manual for the maximum towing capacity.

The Curt 56509 is a powered converter lead wiring harness designed for SUVs and vans. It converts factory vehicle lighting signals to trailer lighting signals via a 4-flat connector, allowing you to tow a trailer with proper lighting control. The system includes a powered converter module that processes turn, brake, and taillight signals from your vehicle's electrical system.
The Curt 56509 is designed for SUVs and vans with 12-volt negative ground electrical systems. The manual does not list specific vehicle makes, models, or years. Contact Curt Manufacturing or consult a fitment database to confirm compatibility with your specific vehicle before purchasing.
No. The Curt 56509 is designed only for 12-volt negative ground systems. Using it on a 24-volt system or a positive ground system will damage the converter and void the warranty.
You will need: ratchet, 10mm socket, wire cutter, wire stripper, crimping tool, panel trim removal tool, large Phillips screwdriver, small Phillips screwdriver, small flathead screwdriver, and an extension. Proper tools will improve installation quality and reduce installation time.
The kit includes a powered converter module, a custom wiring harness with fuse holder, a 10-amp fuse, cable ties, a 4-flat dust cover, double-sided tape for mounting the converter, a ring terminal for the ground wire, a screw for ground attachment, and a white ground wire. The manual does not specify all individual hardware quantities.
Yes. You must disconnect the negative battery terminal before beginning installation. Secure this wire down and away from the battery during the installation process. Reconnect it only after all other installation steps are complete and before testing the system.
The installation difficulty is rated as Moderate. This rating is based on time and effort involved and may vary depending on installer expertise, vehicle condition, and availability of proper tools and equipment.
Yes. You must open the rear hatch and pull the levers on the passenger and driver-side rear walls to allow the seats to fold forward. Then remove the floorboard to gain access to the cargo tray, which must be removed to access the installation area.
The converter module is mounted to the factory electrical module located left of the white housing at the inside of the driver-side rear wheel well. Use the provided double-sided tape to secure the converter to the factory module.
Route the white ground wire down to the floor and under the side wall panel to the area under the cargo tray. Use a 10mm socket to loosen the factory ground bolt, install the custom wiring harness ground to this bolt, and tighten it securely.
Route the 4-flat connector with the center of the vehicle and out of the hatch to the trailer, staying clear of the hatch's latching mechanism. When not in use, roll up and store the connector in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties.
Drilling may be required only for the ground wire attachment. You may need to drill a 3/32" hole in the vehicle body if an existing screw hole is not available for the ring terminal of the white ground wire. Before drilling, check for miscellaneous items that may be behind or under the surface to avoid personal injury or property damage.
No permanent modifications are required. You will use a panel trim removal tool to loosen and remove interior trim panels (threshold, cargo tray, and side wall trim) to access the installation area, but these are reinstalled after installation is complete.
The battery connection must be fuse-protected with a 10-amp maximum fuse. The kit includes a fuse holder with a 10-amp fuse. Install the fuse after all other installation steps are complete. Exceeding this rating can cause loss of warranty, overheating, and potential fire.
Use 12 GA (12-gauge) wire or larger for the power wire routed to the vehicle battery. Route this wire carefully to avoid pinch points and hot or rotating components. When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the wire from sharp edges.
Signal circuits are rated at 3.0 amps per side. Tail and 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.
The converter output wires are: Green for right turn signal, Red for brake, Yellow for left turn signal, and Brown for taillight. These connect to the 4-flat trailer connector. The power lead uses a black wire for positive battery connection and a white wire for ground.
Route the 12 GA black power wire to the vehicle battery location, avoiding pinch points and hot or rotating components. Use a ring terminal to connect the black wire to the positive (+) battery terminal. Disconnect the negative battery terminal before making this connection. Install the 10-amp fuse in the fuse holder after all other steps are complete.
Attach the ring terminal of the white ground wire to the vehicle body using the screw provided. If necessary, drill a 3/32" hole for the screw. Before drilling, check for items behind or under the surface. The ground wire should be routed down to the floor and under the side wall panel to the area under the cargo tray, where it connects to the factory ground bolt.
Locate the white housing at the inside of the driver-side rear wheel well. Install the fuse into the custom harness and plug the harness into this white housing. This connects the converter to the vehicle's factory lighting signals.
Disconnect the negative battery terminal before beginning installation. Do not lay tools across the positive battery terminal (typically marked with red covers or a '+' symbol), as this can cause a short circuit, sparks, and electrical shock. Before drilling, check for miscellaneous items behind or under surfaces to avoid personal injury or property damage. Route the power wire carefully to avoid pinch points and hot or rotating components. Secure the power wire to the vehicle chassis using the provided cable ties.
The maximum fuse rating is 10 amps. Exceeding this rating can cause loss of warranty, overheating, and potential fire. The battery connection must be fuse-protected with a 10-amp maximum fuse to protect the vehicle's electrical system and prevent damage to the converter.
After installation is complete, test for proper function by using a test light or by connecting a properly wired trailer. Verify that all lighting signals (turn signals, brake lights, and taillights) function correctly through the 4-flat connector.
Reinstall all items removed during installation, including the cargo tray, threshold, trim panels, and floorboard. Reconnect the negative battery terminal if it was disconnected at the beginning. Install the provided 4-flat dust cover to help prevent corrosion. Secure any loose wires with the provided cable ties.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. The manual does not specify inspection intervals beyond 'periodic.' Check the vehicle owner's manual or contact the vehicle manufacturer for more information on recommended maintenance schedules.

The manual does not specify a maximum towing capacity. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Consult the vehicle owner's manual or contact the vehicle manufacturer for towing capacity information.
Verify that the negative battery terminal is reconnected after installation. Check that the 10-amp fuse is installed in the fuse holder and is not blown. Confirm that the black power wire is securely connected to the positive (+) battery terminal using the ring terminal. Verify that the white ground wire is securely attached to the vehicle body and that the factory ground bolt is tight. If the fuse is blown, do not reinstall it until the cause of the overload is identified and corrected.
Verify that the custom harness is fully plugged into the white housing at the inside of the driver-side rear wheel well. Confirm that the 10-amp fuse is installed in the fuse holder and is not blown. Check that all wires are securely connected and that there is no visible damage. Test the system using a test light or by connecting a properly wired trailer. If lights still do not function, verify that the vehicle's factory lighting signals are working correctly.
Immediately disconnect the negative battery terminal. Do not reconnect the power wire. Check that no tools are laying across the positive battery terminal, as this can cause a short circuit. Verify that the black power wire is not damaged and that the ring terminal is properly crimped and securely connected to the positive (+) battery terminal. Do not proceed with installation until the cause is identified and corrected. If the issue persists, contact Curt Manufacturing for assistance.
