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 Chevrolet Blazer EV (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 Cadillac XT4, Lyriq, Chevrolet Blazer EV, Equinox EV, and Honda Prologue (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.

Slide the red lock back, press the housing lock in, and remove the dust cover. Install the custom wiring harness into the connector and slide the red lock back into the locked position.
Zip tie the harness as needed with the 4-flat mounted near the receiver hitch. This secures the harness and prevents movement.
Once the harness is connected, verify that it is functioning by attaching the battery (if disconnected) and testing with a test light, 4-flat tester, or a functioning trailer. This confirms proper operation before final reassembly.
Reinstall all items removed during installation. If the negative battery terminal was disconnected at the beginning (XT4 only), reconnect it. Install the provided 4-flat dust cover to help prevent corrosion.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Refer to the product documentation or contact CURT for the specific rating.
Do not lay tools across the positive terminal (typically labeled with red covers or a red '+' symbol). This can cause a ground short, resulting in sparks and/or electrical shocks.
CURT part 56427 fits the Cadillac XT4, Cadillac Lyriq, and Chevy Blazer (including Blazer EV).
You will need a ratchet or wrench and a cutting tool. For Lyriq and Blazer models, also a 7mm socket (Blazer EV) or T-15 Torx bit (Lyriq) and a trim tool.
Battery disconnection is required for Cadillac XT4 only. For Cadillac Lyriq and Chevy Blazer, simply turn off the vehicle.
The manual does not mention drilling as a required step for any supported vehicle model.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Do not lay tools across the positive battery terminal to avoid shorts and electrical shocks.
The CURT 13589 has a gross trailer weight (GTW) capacity of 3,500 lbs. and a tongue weight (TW) capacity of 350 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
The manual does not specify which vehicle makes, models, years, cab styles or bed lengths the 13589 is designed for. Contact CURT product support at 877.287.8634 or visit curtmfg.com to confirm fitment for your specific vehicle.
Required tools are: ratchet, 7mm socket, 3/4" socket, socket extension (3"), torque wrench, die grinder, and rotary tool. For a complete tools reference guide, visit curtmfg.com/trailer-hitch-installation.
The kit includes: 1 trailer hitch, 4 carriage bolts (1/2" - 13 x 1.75"), 4 serrated-flange nuts (1/2"-13), 4 spacers (0.25" x 1.00" x 2.50"), and 4 fishwires (1/2").
The manual requires bumper fascia trimming but does not explicitly state whether the bumper must be fully removed. The installation involves raising the hitch into position behind the bumper cover. Contact CURT support at 877.287.8634 for clarification on your specific vehicle.
You must remove the underbody panel by using a 7mm socket to remove sixteen screws and two push pins (Step 1). After installation, the panel is trimmed and reinstalled (Steps 3 and 5).
The manual states that hole enlargement is required. Step 2 specifies enlarging the access hole using a die grinder or rotary tool. The vehicle frame already has mounting holes; you enlarge the access hole to guide the fishwire and bolts through.
Bumper fascia and underbody panel trimming is required. Step 3 specifies trim dimensions: 3-1/2" on two sides, 2-1/2" on one side, and 2-5/8" on another, with a trim diagram provided for reference. Use the diagram to mark and trim both the underbody panel and bumper cover.
All mounting hardware must be torqued to 90 ft-lbs. This is done in Step 5 after the hitch is positioned and loosely secured with the serrated-flange nuts.
The fishwire is a guide tool that helps you thread the carriage bolts and spacers through the vehicle frame without losing them inside the frame rail. Insert the coiled end through the mounting hole and out the access hole, pass it through the spacer, thread the bolt into the coil, kink the wire to keep the spacer separate, then pull the fishwire, spacer and bolt back through the frame and out the mounting hole. Leave the fishwire attached until Step 4 when you raise the hitch into position.
1. Remove the underbody panel (16 screws with 7mm socket, 2 push pins). 2. Enlarge the access hole and insert fishwires with carriage bolts and spacers into the mounting holes, leaving fishwire attached. 3. Trim the underbody panel and bumper cover using the trim diagrams. 4. Raise the hitch into position behind the bumper cover, remove fishwires, and loosely secure with serrated-flange nuts. 5. Torque all hardware to 90 ft-lbs. and reinstall the underbody panel.
Safety glasses must be worn at all times during installation. Never exceed your vehicle manufacturer's recommended towing capacity. Proper tools will improve installation quality and reduce time required.
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. This helps prevent damage to the product or vehicle.
The manual states that periodic inspection should be performed to ensure all mounting hardware remains tight and structural components are secure, but does not specify an inspection interval. Contact CURT support at 877.287.8634 for recommended maintenance intervals.
