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 Ford Edge and Lincoln MKX (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 4,000 lbs. GTW and 400 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.
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 Lincoln MKX (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 11 - 15 Lincoln MKX Fits beneath factory 1-1/4" receiver Curt 2", Class 3 Trailer Tow Hitch + 4-flat Wiring Kit 13067 (Part #CHW-2203) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Part number 13067 fits Ford Edge and Lincoln MKX models. However, it is specifically designed for Edge Sport with fascia trimming. Fascia trimming may be required on Edge Sport, and the manual does not confirm fitment on other Edge trim levels or MKX variants without additional modifications. Verify your vehicle's trim level and year before purchasing.
Fascia trimming may be required on Edge Sport. The manual includes a fascia trim diagram with specific dimensions (8.000 in. wide, 2.50 in. height, 4.00 in. offset) for Edge Sport. If your vehicle is an Edge Sport, plan for fascia trimming. The manual does not specify whether trimming is required on other trim levels or the Lincoln MKX.
The kit includes: 2× 1/2-13 UNC 1-3/4" grade 8 carriage bolts (part 10-10272), 4× 1/2-13 UNC 1-1/2" grade 8 carriage bolts (part 10-10287), 6× 1/2-13 UNC serrated flange nuts (part 20-00062), 6× 0.250 × 1.25 × 3.00" square hole spacers (part CM-SP19), and 4× 1/2" fishwire (part 1_2 FISHWIRE).
Required tools are: ratchet, torque wrench, 6" socket extension, 3/4" socket, 8mm socket, flat head screwdriver, drill with 17/32" drill bit, tin snips, and wire. The wire is used to hold the exhaust up during installation to prevent damage.
Yes. Step 1 requires lowering the exhaust by removing the rear 3 exhaust hangers. You may need to use wire to hold the exhaust up high enough to prevent damage during installation. The exhaust is reinstalled in Step 8 after the hitch is secured.
Remove the heat shield from both sides of the vehicle by removing 3× 6mm bolts and 1× black plastic plug from each side. The driver side heat shield is also connected to the rear wiring harness by a plastic plug—disconnect this. After removal, trim off the tab from both driver and passenger side heat shields. Reattach the heat shield without the screws in the frame rails; it will be sandwiched between the vehicle frame rails and hitch.
Yes. Drilling is required. In Step 5, you must drill the rear holes of the hitch on both sides using a 17/32" drill bit. The hitch is used as a template for hole placement.
Drilling the frame rails (17/32" holes in Step 5) is permanent. Heat shield tab trimming is permanent. Fascia trimming on Edge Sport (per the trim diagram) is permanent. The exhaust lowering and heat shield removal are reversible. Factory bolts are not reused and should not be reinstalled.
All 1/2" hardware must be torqued to 110 lb-ft. This is applied in Step 7 after all fasteners are installed and the hitch is in position.
The gross load capacity when used as a weight-carrying hitch is 4,000 lbs. trailer weight and 400 lbs. tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
Fishwire is a method of threading fasteners through existing holes without drilling new ones at that stage. In Steps 3 and 6, you thread 1/2-13 carriage bolts with CM-SP19 spacers through the rear of bumper mounts and into holes in the frame rails using the fishwire hardware, then secure with 1/2" flange nuts. The manual includes a Fishwire Technique Diagram for reference.
1. Fishwire 1/2-13 × 1-1/2" carriage bolts with spacers through rear bumper mounts to frame rail holes, secure with flange nuts (Step 3). 2. Raise hitch into position and secure with 1/2" flange nuts (Step 4). 3. Drill rear holes of hitch using 17/32" drill bit (Step 5). 4. Fishwire 1/2-13 × 1-3/4" carriage bolt and spacer through bumper mounts, attach with flange nuts (Step 6). 5. Torque all 1/2" hardware to 110 lb-ft (Step 7).
No. The manual explicitly states 'DO NOT REINSTALL FACTORY BOLTS.' Use only the hardware provided in the kit.
The hitch has a gross load capacity of 4,000 lbs. trailer weight and 400 lbs. tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the hitch rating. Always follow your vehicle's towing limits.
After installation, verify that all fasteners are tight and all structural components are sound. The manual recommends periodically checking the receiver hitch to ensure all fasteners remain tight and structural integrity is maintained.

Yes, the Curt 56121 is designed for the Lincoln MKX. It is a custom wiring harness for SUVs, mini and full-sized vans.
The Curt 56121 is a custom wiring harness that integrates with your vehicle's taillight system. It includes a converter box and a 4-flat connector for trailer use. The harness handles signal circuits (3.0 amps per side) and tail/running circuits (6.0 amps total).
You will need a ratchet, 10mm socket, and panel trim removal tool. You may also need a drill if you do not have a suitable existing screw for the ground wire attachment.
The harness includes a custom wiring harness with yellow and green wire ends, a black converter box, a white ground wire with ring terminal, a provided screw for grounding, double-sided tape for the converter box, cable ties, sealant for the grommet, and a 4-flat dust cover.
Yes. You must open the vehicle tailgate and remove the two 10mm bolts securing the taillight, then carefully pull the taillight rearward without damaging the locking tabs. This gives you access to the taillight wiring harness connectors.
You must remove the floor mats, spare tire compartment cover, rear scuff panel, and plastic storage trays surrounding the spare tire. These removals provide access to route the wiring harness from the taillight area through the interior.
Drilling may be required. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, you will need to drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint before installation.
Yes. You must locate the grommet behind the taillight where the vehicle taillight wiring passes through from inside the cabin. Remove the grommet and cut a slit large enough to route the custom wiring harness through it. After routing the harness, reseat the grommet using the provided sealant to seal the cut and around all wires.
The harness has three main wires: yellow wire (driver side taillight connection), green wire (passenger side taillight connection), and white ground wire (vehicle frame grounding point). The black converter box connects to the vehicle battery via a black power wire, which must be routed as shown on the included CME-PCL-INS sheet.
Yes. The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower.
Separate the vehicle's taillight wiring harness connectors from the taillight housing, taking care not to damage the locking tabs. Route the custom harness end with the yellow wire (driver side) or green wire (passenger side) through the grommet slit. Insert the custom harness end between the separated connectors and ensure the connectors are fully inserted with locking tabs in place.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. When in use, route it to the center of the vehicle and out of the trunk. Secure any loose wires with the provided cable ties.
All steps must be followed to ensure the wiring harness functions properly. Test for proper function by using a test light or connecting a properly wired trailer. This confirms that the signal and tail/running circuits are operating correctly.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. The area for the ground wire screw should be free of rust, dirt and paint.
The product is rated for signal circuits of 3.0 amps per side and tail/running circuits of 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower, as this can cause loss of warranty, overheating and potential fire.
