Whatever the next checkpoint is on your adventure -- whether it's getting your bike on the trail before sunrise or making it to the campground before dark -- CURT class 2 hitches let you Bring It with confidence. These receiver hitches are made to handle most light-duty towing applications and offer a custom fit for your vehicle. Typically used on full-size cars, crossovers, compact SUVs, minivans or even compact pickup trucks, a CURT class 2 trailer hitch complements the design of smaller vehicles. This particular class 2 hitch is made to be a custom hitch for certain years of the Ford Escape, Mazda Tribute and Mercury Mariner (to verify vehicle compatibility, see application info). It offers a weight carrying capacity of 3,500 lbs. GTW and 350 lbs. TW. Class 2 trailer hitches can typically be used to tow a variety of lightweight trailers, such as a small utility trailer, small fishing boat trailer or popup camper (NOTE: Never exceed the lowest weight capacity of any towing component). They are also perfect for adding cargo space to your vehicle with a bike rack or cargo carrier. This class 2 hitch features a 1-1/4" receiver tube to accept a ball mount shank or other hitch-mounted accessory. For safety, it is tested in accordance with SAE J684. A custom trailer hitch design requires extra care, and as such, CURT class 2 hitches are engineered using real vehicles and hands-on research. We use high-strength steel, robotic welding and rigorous testing to produce hitches that are built to fit your lifestyle. To ensure that each hitch will be a reliable extension of your vehicle, we also finish our hitches in a co-curing of liquid A-coat and black powder coat, giving them long-lasting rust and wear resistance.
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 Ford Edge, Ford Escape, Ford Freestar, Lincoln MKX, Mazda Tribute and Mercury Mariner (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 12060 is designed for the Ford Escape, Mazda Tribute, and Mercury Mariner. The hitch is a receiver-style hitch with a gross load capacity of 3,500 lbs trailer weight and 350 lbs tongue weight. Do not exceed your vehicle manufacturer's recommended towing capacity.
Curt 12060 is designed for use with ball mount #D-55001-55. Euro mount options are also available: #45571 (1-7/8" ball) and #45572 (2" ball).
The gross load capacity when used as a weight-carrying hitch is 3,500 lbs trailer weight and 350 lbs tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
The hitch includes: 6× 1/2-13 UNC grade 8 carriage bolts (1-3/4" long), 6× 1/2-13 UNC grade 8 hex nuts, 6× 1/2" conical tooth washers, 6× 0.250 × 1.00 × 3.00" square hole spacers, 1× 0.375 × 1.25 × 2.50" square hole spacer, and 2× 1/2" fishwire.
Required tools are: ratchet, 3/4" socket, torque wrench, and die grinder with carbide bit. The die grinder is needed because drilling may be required to create access holes in the frame rail.
Drilling may be required. If your vehicle has access to put the bolt and spacer into the frame rail from the end, no drilling is needed. Some vehicles have different tie-down hooks that allow access to frame rail ends. If access is not available, you may need to drill an access hole in the frame using a die grinder with carbide bit.
If your vehicle is equipped with an exhaust vibration dampener that interferes with the side plate, you will need to bend or pry the dampener away from the side plate as needed. This may require modification of the exhaust bracket.
1. Use fishwire to pull carriage bolts and square hole spacers through holes in the bottom of the frame rail (may require drilling an access hole). 2. Place spacer on passenger side bolt and raise hitch into position. Hand tighten the fasteners. 3. Fishwire the remaining fasteners into position and secure with conical tooth washers and hex nuts. 4. Torque all 1/2" fasteners to 110 lb-ft.
All 1/2" fasteners must be torqued to 110 lb-ft. Use a torque wrench to ensure proper tightening.
Non-trailer loads can be applied to this hitch only if they are supported by 18050 stabilizing straps. Failure to properly support non-trailer loads will void the product warranty.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This helps maintain safe operation and preserve the warranty.

Yes. Step 1 requires you to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal before beginning installation.
Open the vehicle tailgate and remove the two Phillips screws securing the driver side taillight assembly. Remove the taillight assembly to locate the vehicle taillight wiring harness connectors. From underneath the vehicle, locate the access hole on each side leading to the taillight wiring harness under the taillight.
The custom wiring harness end with the yellow wire routes to the driver side taillight housing assembly. Route it up from under the vehicle through the body opening to the driver side taillight.
The custom wiring harness end with the green wire routes to the passenger side taillight. Route it behind the removed scuff panels on the passenger side.
Separate the black vehicle connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place.
Drilling may be required. You should first locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing screw is available, drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Drill a 3/32" pilot hole for the provided ground screw if a suitable existing screw with nut is not available in the vehicle frame near the connector.
Secure the white ground wire using the ring terminal and provided screw at a suitable grounding point near the connector. The grounding point should be an existing screw with nut in the vehicle frame, or a 3/32" pilot hole you drill. The area must be free of rust, dirt and paint.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape.
When in use, route the 4-flat to the center of the vehicle. When not in use, roll it up and store in a convenient, out of the way location. Secure any loose wires with the provided cable ties.
Reinstall all items removed during installation and reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion. Test for proper function by using a test light or connecting a properly wired trailer.
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 battery connection must be fuse protected with a maximum of 10 amps.
