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 Lexus NX250, NX350, NX350h, and NX450h+, and Toyota RAV4 and Venza (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 4,500 lbs. GTW and 675 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 4,500 lbs. WD and 675 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 Honda Civic (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, the Curt 56396 custom wiring harness is designed for Honda Civic sedans. Verify your vehicle matches the application before purchasing.
The Curt 56396 is a custom wiring harness that connects your vehicle's electrical system to a trailer connector. It includes a converter box and a 4-flat connector for towing applications.
The package includes the custom wiring harness with yellow and green wire ends, a black converter box, a white ground wire with ring terminal and screw, a 4-flat connector, a 4-flat dust cover, double-sided tape for the converter box, cable ties, and sealant for the grommet.
The battery connection must be fuse-protected with a 10-amp maximum. Exceeding this rating can cause loss of warranty, overheating and potential fire.
Signal circuits are rated at 3.0 amps per side. Tail and running circuits are rated at 6.0 amps total. Do not exceed these ratings or the tow vehicle lamp load rating, whichever is lower.
Required tools are: ratchet, ratchet extension, 8mm socket, flat blade screwdriver, panel trim removal tool, wire stripper, wire crimper, and cutting tool.
The manual does not specify whether the battery must be disconnected. Consult your vehicle owner's manual or contact the vehicle manufacturer for guidance on safe electrical work procedures.
Drilling may be required. Step 9 instructs you to locate an existing screw with nut in the vehicle frame for the ground wire, or drill a 3/32" pilot hole if no suitable existing fastener is available. Before drilling, check for miscellaneous items hidden behind or under surfaces to avoid damage and personal injury.
Drill a 3/32" pilot hole if no existing screw with nut is available in the vehicle frame near the connector.
Yes. Locate the grommet behind the taillight where the vehicle taillight wiring passes through. Remove the grommet and cut a slit large enough to route the custom wiring harness through. After routing the harness, reseat the grommet and use the provided sealant to seal the cut and around all wires.
1. Open trunk and remove floor coverings and storage trays. 2. Remove scuff panel. 3. Remove driver side felt liner push fasteners. 4. Remove driver side taillight using two 8mm fasteners. 5. Disconnect taillight wiring connectors. 6. Remove grommet and cut slit for harness routing. 7. Route yellow wire end through grommet and insert between separated connectors. 8. Reseat grommet and seal with provided sealant. Reinstall taillight. 9. Secure white ground wire to vehicle frame. 10. Route green wire end to passenger side and repeat steps 3-8. 11. Adhere converter box inside vehicle. 12. Route battery power wire per included CME-PCL-INS sheet. 13. Route 4-flat connector to vehicle center when in use; store when not in use. 14. Reinstall all removed items and install 4-flat dust cover.
On the outside of the vehicle, locate the taillight. Remove the two 8mm fasteners securing the taillight in place. Gently pull the taillight rearward, taking care not to damage the alignment tabs on the back.
Locate the vehicle taillight wiring harness connectors behind the removed taillight. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. Route the custom wiring harness end with the yellow wire through the grommet slit and insert it between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place.
Locate a flat spot inside the vehicle near the taillight. Adhere the black converter box using the provided double-sided tape.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no existing fastener is available, drill a 3/32" pilot hole. The area should be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw. Before drilling, check for miscellaneous items hidden behind or under surfaces to avoid damage and personal injury.
Route the custom wiring harness end with the green wire down behind the interior side panel and out to the passenger side behind the removed scuff panel. Repeat steps 3-8 on the passenger side using the harness end with the green wire.
When not in use, roll up the 4-flat connector and store it in a convenient, out of the way location. Secure any loose wires with the provided cable ties.
Test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring harness will function properly.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
After installation, test for proper function by using a test light or connecting a properly wired trailer. Verify that all removed items have been reinstalled, the 4-flat dust cover is installed, and all loose wires are secured with cable ties.

The manual does not specify which vehicle makes, models, or years are compatible with the 13615. Contact CURT product support at 877-287-8634 or check the product listing on curtmfg.com to confirm fitment for your vehicle.
No. The 13615 installation requires use of existing weldnuts and no drilling.
You will need: ratchet, torque wrench, 8" socket extension, 19mm torque adapter, 12mm socket, 17mm socket, and 19mm socket. Safety glasses are required. For a tools reference guide, visit curtmfg.com/trailer-hitch-installation.
Torque the M12 hardware to 86 ft-lbs.
Gross trailer weight (GTW): 4,500 lbs. Tongue weight (TW): 675 lbs. Weight distribution (WD): 4,500 lbs. WD tongue weight (WDTW): 675 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
Yes. Remove the stickers covering the existing weldnut holes on the outside of the frame rails. If equipped, remove the tie-down bracket from the bottom passenger-side frame rail using a 12mm socket and return it to the vehicle owner.
The package includes: 1 trailer hitch, 4 hex bolts (M12 – 1.25 x 35mm), and 4 conical-toothed washers (1/2").
To remove debris from the 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.
The conical-toothed washers should be oriented with the toothed side facing the hitch side plate, as shown in the assembly diagram on page 2. The washer sits between the hex bolt and the hitch side plate.
No. In Step 3, loosely secure the hitch with the M12 bolts and conical-toothed washers. Tighten them to the final torque specification of 86 ft-lbs only in Step 4, after the hitch is positioned correctly.
If the heat shield contacts the hitch, bend the heat shield up to prevent rattling. This may be necessary on some vehicle models.
Yes. Lowering the exhaust may ease installation on some models. If you do lower the exhaust, be sure to support it to prevent damage to the vehicle.
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. The manual does not specify an exact interval; consult your vehicle owner's manual or contact CURT support at 877-287-8634 for recommended inspection frequency.
Safety glasses should be worn at all times while installing this product. Never exceed your vehicle manufacturer's recommended towing capacity when using the hitch.
