Yes, CURT part number 13439 is designed for 2018-Present GMC Terrain SUVs. Before purchasing, verify your vehicle matches this model and year range, and confirm that your vehicle's towing capacity meets or exceeds the hitch specifications.
When used as a weight-carrying hitch, the maximum trailer weight is 4,500 lbs. and tongue weight is 675 lbs. When used as a weight-distribution hitch, the same capacities apply. Never exceed your vehicle manufacturer's recommended towing capacity.
The hitch weight is 30 lbs.
Required tools are: ratchet, 15 mm and 3/4" sockets, 6" socket extension, T15 Torx bit socket, pry bar, torque wrench, rotary tool, and safety glasses. Proper tools greatly improve installation quality and reduce installation time.
The hitch includes: 6 carriage bolts (1/2-13 UNC, 1-1/2", Grade 8, part number 10-10287), 6 serrated flange nuts (1/2-13 UNC, Grade 8, part number 20-00062), 6 square hole spacers (0.250 x 1.00 x 3.00", part number CM-SP6), and 6 pieces of 1/2" fishwire (part number 1_2 FISHWIRE).
No drilling is required. The hitch uses existing frame rail access holes. However, you must slightly enlarge the access holes on both the driver and passenger side frame rails to allow the hardware to fit.
Yes. You must slightly enlarge the access holes on both the driver and passenger side frame rails to allow the hardware to fit. The manual indicates the access hole diameter is approximately 1.08". Use a rotary tool to enlarge the holes. This is a permanent modification to the vehicle frame.
Yes. The exhaust must be temporarily lowered during installation. Remove the 4 bolts from the rear exhaust hanger brackets (2 per side) using a 15 mm socket, then remove the exhaust rubber isolator in front of the muffler. Be sure to support the exhaust during this process. After hitch installation is complete, reinstall the exhaust.
Two people may be required to ease installation. The manual recommends reading all instructions thoroughly before beginning and notes that using proper tools will greatly improve the quality of the install and reduce the time required. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance.
Professional installation time is approximately 60 minutes. Novice (DIY) installation time is approximately 45 minutes. Actual time may vary depending on experience and familiarity with the vehicle.
The first step is to locate and remove the 2 Torx screws from the rear fascia. Save these screws for reinstallation at the end of the installation process.
After enlarging the access holes on both frame rails, utilize the access hole to fishwire one 1/2" carriage bolt and one spacer into each of the three mounting holes in both frame rails. This allows you to position the bolts through the frame without fully inserting them, making it easier to align the hitch before final tightening.
Raise the hitch into position and secure it to the vehicle using 6 of the 1/2" hex flange nuts (part number 20-00062) included with the hitch. Each nut fastens one of the carriage bolts that was previously fishwired into the frame rails.
Torque all 1/2" hardware to 110 ft-lb. Use a torque wrench to ensure proper tightening. After installation, periodically check that all fasteners remain tight.
After torquing the 1/2" hardware to 110 ft-lb, reinstall the exhaust and the 2 Torx fascia screws that were removed in step 1. This completes the installation.
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 all structural components remain in good condition throughout the life of the hitch.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. The manual does not specify an exact interval, but regular inspection is recommended to maintain safe operation.
Safety glasses should be worn at all times while installing this product. When lowering the exhaust, be sure to support it properly to prevent injury or damage. Never exceed your vehicle manufacturer's recommended towing capacity when using the hitch.
Never exceed your vehicle manufacturer's recommended towing capacity. CURT part number 13439 is rated for a maximum trailer weight of 4,500 lbs. and tongue weight of 675 lbs. when used as either a weight-carrying or weight-distribution hitch. However, your vehicle's manufacturer may specify a lower capacity, which must be observed.

The kit includes: one 30 amp auto-resetting circuit breaker, two #10 ring terminals, two 3/8" ring terminals, two 1/2" ring terminals, three 12-10 gauge butt connectors, 10 feet of 10 ga black/white duplex wire, 20 feet of 10 ga blue cross-linked wire, and eight 8.5" cable ties.
Yes, but with a critical difference: these vehicles require the stop signal wire to be spliced to the light green wire on the turn signal harness connector under the dash, not to the brake pedal switch. Do NOT connect to the red wire with green stripe, as serious damage may occur. All other vehicles connect to the brake pedal switch instead.
You will need: a test light, wire stripper/cutter, crimp tool, and 3/8" box end wrench. The test light is used to identify the cold (switched) side of the brake pedal switch.
Yes. The manual cautions to disconnect the tow vehicle's negative battery cable before installation. Reconnect it only in the final step after all wiring is complete.
Mount the 30 amp circuit breaker near the tow vehicle's positive battery terminal. This keeps the power wire run as short as possible and protects the circuit.
Use 10 gauge (10 ga) black wire from the duplex wire included in the kit. Strip 3/8" of insulation from each end. Crimp a #10 ring terminal to the end that attaches to the circuit breaker stud labeled 'BAT', and a 3/8" or 1/2" ring terminal (sized to fit your battery terminal) to the end that attaches to the positive battery terminal.
Feed the 10 ga duplex wire from the brake controller in the cockpit through the firewall into the engine compartment toward the battery. Cut to length as needed. At the battery end, crimp a 3/8" or 1/2" ring terminal to the white wire and a #10 ring terminal to the black wire. Attach the black wire to the circuit breaker stud labeled 'AUX' and tighten the nut with a 3/8" box end wrench.
When passing the duplex wire through the firewall into the engine compartment, use an existing grommet, add a new grommet, or fill the hole with silicone rubber to insulate and protect the wire. The same protection applies when passing the blue cross-linked wire through any sheet metal at the rear of the vehicle.
In the cockpit, attach the black duplex wire to the brake controller's battery wire (typically black) and the white duplex wire to the brake controller's ground wire (typically white). Use either one of the supplied yellow butt connectors or solder the leads together and insulate with heat shrink tubing.
Locate the brake pedal switch on the back side of the vehicle's brake pedal. Use a test light or volt meter to identify the 'cold' or switched side—this terminal will only show power when the brake pedal is depressed. Attach the stop signal wire (typically red) from the brake controller to the cold side of the switch using a wire tap.
Locate the semi-circle turn signal harness connector on the steering column under the dash. It has two rows of wires: a row of four and a row of seven. Attach the stop signal wire (typically red) from the brake controller to the light green wire using a wire tap. Do NOT connect to the red wire with green stripe, as serious damage may occur.
Feed the 10 ga blue cross-linked wire from the brake controller to the trailer connector at the rear of the vehicle, taking up any slack in the wire. When passing through any sheet metal, use an existing grommet, add a new grommet, or fill the hole with silicone rubber to protect the wire.
Attach the blue cross-linked wire to the brake controller's electric brake wire (typically blue) using one of the supplied yellow butt connectors or by soldering and insulating with heat shrink tubing. At the rear of the vehicle, trim any loose blue wire and attach it to the trailer connector's electric brake terminal. Refer to the trailer connector's wiring diagram for the correct terminal location.
Secure any loose wires with the cable ties provided. Connect the black power wire from the circuit breaker to the positive side of the battery. Connect the white ground wire from the brake controller to the negative side of the battery. Finally, reconnect the tow vehicle's negative battery cable to the battery.
The circuit breaker is 30 amps and auto-resetting. It must be mounted near the positive battery terminal and connected directly to the positive battery terminal via the included black 10 gauge wire.
Use a 3/8" box end wrench to tighten the nuts on the circuit breaker studs labeled 'BAT' and 'AUX'.
The kit includes 10 feet of 10 gauge black/white duplex wire for the battery and brake controller connections, and 20 feet of 10 gauge blue cross-linked wire for the electric brake signal to the trailer connector.
Black wire connects to the positive battery and circuit breaker. White wire connects to the brake controller ground and negative battery. Red wire is the stop signal wire from the brake controller. Blue wire is the electric brake signal wire. The manual notes these are 'typically' these colours but recommends confirming with your brake controller documentation.
Yes. You can solder the leads together and insulate with heat shrink tubing as an alternative to using the supplied yellow butt connectors. This applies to connections between the duplex wire and the brake controller wires, and between the blue cross-linked wire and the brake controller.
The black power wire must connect directly to the positive battery terminal via the 30 amp circuit breaker. Connecting to the fuse panel or any other accessory wiring may damage vehicle wiring and cause trailer brake failure. The circuit breaker protects the circuit and must be the only protection between the battery and the brake control system.
Do NOT connect the stop signal wire to the red wire with green stripe on the turn signal harness. Serious damage may occur. Connect only to the light green wire. Also, do not connect to the brake pedal switch on these vehicles; use the turn signal harness instead.
The kit is universal but requires an existing trailer connector and brake controller. 1989-1991 Ford E & F-Series with ABS use a different stop signal connection (turn signal harness instead of brake pedal switch). Consult your brake controller documentation for compatibility.
No drilling is required. The kit connects to existing components: the battery, brake controller, brake pedal switch (or turn signal harness on 1989-1991 Ford E & F-Series with ABS), and trailer connector.
Do NOT connect the stop signal wire to the red wire with green stripe on the turn signal harness—serious damage may occur. Connect to the light green wire instead, and do not use the brake pedal switch.
Connecting to the fuse panel or accessory wiring may damage vehicle wiring and cause trailer brake failure. The 30 amp circuit breaker must be the only protection between the battery and the brake control system.
The Curt 56375 is a custom wiring connector that provides a 4-flat trailer connector interface for your vehicle. It connects to the vehicle's existing wiring connector located along the rear bumper and allows you to connect a trailer with proper lighting control. The connector includes relays that must be installed in the vehicle's fuse panel (positions K2 and K3) to manage signal and tail/running light circuits.
Yes, the Curt 56375 is designed for Chevrolet Equinox SUVs, Mini & Full-Sized Vans (S). The connector mounts behind the center of the rear bumper. If you have a different vehicle model or year, contact the manufacturer or consult a fitment database to confirm compatibility.
You need a flat blade screwdriver and a cutting tool. The screwdriver is used to remove the fuse panel cover, and the cutting tool may be needed during installation. The manual does not specify additional tools or whether professional installation is recommended.
The kit includes the custom wiring connector, two relays (for installation in fuse panel positions K2 and K3), a 4-flat dust cover, and cable ties for securing loose wires.
The vehicle wiring connector is located along the rear bumper, behind the center. It will be similar in appearance to the custom wiring connector included in the kit. You will separate this connector from the weather seal connector as the first step of installation.
1. Locate the vehicle wiring connector along the rear bumper. 2. Carefully separate the vehicle connector from the weather seal connector, taking care not to damage the locking tabs. 3. Insert the custom wiring connector end into the vehicle connector. 4. Ensure the connectors are fully inserted with locking tabs in place. The connectors must be fully seated for proper function.
The two relays must be installed in the vehicle's fuse panel in positions K2 and K3. To access the fuse panel: 1. Open the vehicle tailgate. 2. On the driver side, locate the fuse access panel cover on the side trim. 3. Remove the fuse panel cover. 4. Install the relays in positions K2 and K3 as shown on the fuse cover. 5. Reinstall the fuse panel cover.
When in use, route the 4-flat out from the vehicle. When not in use, roll it up and store it in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties to prevent damage and maintain a neat appearance.
The provided 4-flat dust cover helps prevent corrosion of the connector. Install it after the custom wiring connector is fully connected to the vehicle connector. The manual does not provide specific installation details beyond this instruction.
Signal Circuits are rated at 7.5 amps per side. Tail/Running Circuits are rated at 7.5 amps total. Do not exceed these ratings 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 Curt 56375 is rated for Signal Circuits at 7.5 amps per side and Tail/Running Circuits at 7.5 amps total.

The 4-way flat electrical adapter converts a vehicle's 4-way flat trailer connector to other trailer connector types (6-way round, 7-way RV blade, or dual 4-way flat). This allows you to tow trailers with different connector styles. Single-output models (57184, 57183, 57185, 57626, 57676) convert to one connector type; dual-output models (57604, 57624, 57672, 57674, 57102) provide two different connector outputs simultaneously.
Yes. Your vehicle must be equipped with a 4-way flat trailer connector. If your vehicle does not have one, you will need to install a custom wiring harness or other 4-way flat trailer connector before installing this adapter.
Both convert a 4-way flat connector to a 7-way RV blade. The difference is that 57185 includes a mounting bracket, while 57184 does not.
Both convert a 4-way flat connector to a 6-way round. The difference is that 57626 includes a mounting bracket, while 57183 does not.
Curt offers three dual-output models that provide both a 4-way flat and a 7-way RV blade output: part numbers 57672, 57674, and 57102. All three include a mounting bracket.
Curt offers two dual-output models that provide both a 4-way flat and a 6-way round output: part numbers 57604 and 57624. Both include a mounting bracket.
You will need: a 1/8" drill bit, drill, Phillips screwdriver, wire stripper, cutting tool, terminal crimpers, and a test light. The manual also lists three self-tapping screws (#10 - 1/2") as required, though these are not included with the product.
No. The three self-tapping screws (#10 - 1/2") used to attach the mounting bracket are not included and must be purchased separately.
Mount the combination harness in a location on the tow vehicle that is within reach of the trailer's wiring harness and near the center of the vehicle. The mounting bracket (if included) should be attached to the vehicle's bumper or other suitable surface.
Yes. You must drill two 1/8" holes: one for the grounding point and one (or more) for the mounting bracket. Before drilling, you must check for brake lines, fuel lines, wiring and other components that may be hidden behind or under the surface to avoid damage.
No. You must never attach the mounting bracket directly to the hitch by cutting, welding or drilling into the hitch. Mount it to the vehicle's bumper or other suitable surface instead.
The adapter uses four wires: Yellow (auxiliary or back-up lights), Blue (electric brakes), Black (positive power with appropriate inline fuse), and White (ground). All wires except black and white must be connected using 12 gauge (minimum) wire and butt connectors to the appropriate vehicle functions.
The white wire is the ground connection. It must be attached with a ring terminal to a 1/8" hole drilled in a suitable grounding point on the vehicle using a #10 - 1/2" self-tapping screw. This ground connection is required for the harness to work properly. The white wire on the vehicle's 4-way flat connector does not support the ground (-) functions of the combination harness.
Yes. The black wire (positive power) must be connected with an appropriate inline fuse. The manual does not specify the fuse amperage rating.
Use 12 gauge (minimum) wire for all connections. The manual specifies this minimum gauge for the remaining wires (yellow, blue, and black) when connecting to appropriate vehicle functions.
Failing to properly ground the product can cause loss of warranty, overheating and potential fire. The white wire must be securely attached to a clean grounding point using a #10 - 1/2" self-tapping screw in a 1/8" hole. The area must be clean of dirt, debris or undercoating.
Before drilling, you must check for brake lines, fuel lines, wiring and any other components that may be hidden behind or under the surface. Drilling into these components can cause damage and personal injury.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding either rating can cause damage or unsafe operation.
Confirm proper function with a test light or by using a properly functioning trailer. This verifies that all connections are working correctly before towing.
Secure any loose wires using cable ties or equivalent product to prevent them from moving, catching on components, or becoming damaged.
Your vehicle must have a 4-way flat trailer connector. If it does not, you will need to install a custom wiring harness or other 4-way flat connector first. Check the part number table to confirm the adapter converts to the connector type you need.
You must purchase three #10 - 1/2" self-tapping screws for the mounting bracket. You will also need an appropriate inline fuse for the black (positive power) wire; the manual does not specify the amperage.
Yes, you must drill two 1/8" holes: one for grounding and one for the mounting bracket. Before drilling, check for brake lines, fuel lines and wiring behind the surface. Never drill into the hitch.
Yellow = auxiliary/back-up lights; Blue = electric brakes; Black = positive power (needs inline fuse); White = ground (must be properly grounded or warranty is void and fire risk exists). Use 12 gauge minimum wire and butt connectors.
Proper grounding of the white wire is critical. Failing to ground it properly can cause loss of warranty, overheating and fire. The grounding point must be clean of dirt, debris and undercoating.
Test with a test light or by using a properly functioning trailer to confirm all connections work. Secure loose wires with cable ties.
