Yes, CURT part number 13293 is designed for 2017-Present GMC Acadia SUVs. Confirm your vehicle year matches this range before purchasing. The hitch is a weight-carrying receiver hitch with a maximum gross load capacity of 5,000 lbs trailer weight and 750 lbs tongue weight, or 6,000 lbs trailer weight and 750 lbs tongue weight when used as a weight distribution hitch. Always verify your vehicle's manufacturer towing capacity and do not exceed it.
When used as a weight-carrying hitch, the maximum gross load capacity is 5,000 lbs trailer weight and 750 lbs tongue weight. When used as a weight distribution hitch, the capacity is 6,000 lbs trailer weight and 750 lbs tongue weight. The hitch itself weighs 40 lbs. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower than these ratings.
CURT 13293 fits 2017-Present GMC Acadia SUVs only. Do not exceed your vehicle manufacturer's recommended towing capacity.
No, drilling is not required. The hitch uses existing frame holes and access holes. Trimming of the exhaust heat shield is required.
Required tools are: torque wrench, ratchet, 15mm socket, 11/16" socket, 8" socket extension, pliers (needle nose for speed nuts), utility knife, aviation shears, and safety glasses. A 15mm socket may also help with removing rearmost exhaust brackets to ease lowering the exhaust.
The kit includes 6 carriage bolts (7/16-14 UNC, 1-1/4", Grade 8), 6 serrated flange nuts (7/16-14 UNC, Grade 8), 6 square hole spacers (0.250 x 0.88 x 2.25"), and 6 pieces of 7/16" fishwire.
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.
Professional installation time is approximately 37 minutes. Novice (DIY) installation time is approximately 40 minutes. Actual time may vary depending on your experience level and familiarity with the vehicle.
The first step is to lower the exhaust by removing 3 rubber isolators as shown in the Rubber Isolator Removal Diagram. The manual notes that removing the rearmost exhaust brackets from the vehicle frame using a 15mm socket may ease lowering the exhaust.
Yes, heat shield trimming is required. Remove 4 speed nuts on each side using needle nose pliers, then trim the heat shield using aviation shears as shown in the trim diagram. The manual notes that all dimensions are approximate and you should confirm fit prior to trimming. After trimming, reinstall the heat shields.
The heat shield should be trimmed approximately 4.00" (typical) and 12.00" (typical) as shown in the Heat Shield Diagram. All dimensions are approximate; confirm fit prior to trimming.
Fishwire 3 CM-SP2 spacers and 3 7/16" carriage bolts through the access holes and out the mounting holes on each frame rail. This technique allows you to guide the fasteners through the frame without drilling. The fishwire is used to pull the bolts and spacers through the access holes to the mounting holes on both the driver and passenger side frame rails.
After fishwiring the spacers and bolts, use pliers to remove 2 heat shield vehicle studs on each side. Raise the hitch into position and secure it with 6 7/16" flange nuts (3 on each side). The manual notes to scrape away excess caulk using a utility knife for proper installation.
Torque all 7/16" hardware to 59 ft-lbs using an 11/16" socket.
Use an 11/16" socket to torque all 7/16" hardware to 59 ft-lbs.
You have two options: either remove the Lower Panel Hitch Door and return it to the vehicle owner, or trim it as shown in the diagram (approximately 3" wide by 1.5" up). The choice depends on your preference and the vehicle owner's needs.
Yes. After torquing all 7/16" hardware to 59 ft-lbs, raise the exhaust back into position and reinstall the rubber isolators that were removed in Step 1.
Safety glasses must be worn at all times while installing this product. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance. Read all instructions thoroughly before beginning installation.
Never exceed your vehicle manufacturer's recommended towing capacity. While CURT 13293 has a maximum gross load capacity of 5,000 lbs trailer weight and 750 lbs tongue weight (weight-carrying) or 6,000 lbs trailer weight and 750 lbs tongue weight (weight distribution), your vehicle's manufacturer may specify a lower limit. Always follow the vehicle manufacturer's recommendation.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This ongoing maintenance is important for safe operation.
The manual recommends periodically checking the receiver hitch to ensure all fasteners are tight and all structural components are sound. No specific interval is provided; establish a regular maintenance schedule based on your towing frequency and usage.
The hitch weighs 40 lbs.
Yes, CURT 13293 complies with safety specifications and requirements for connecting devices and towing systems of the state of New York, V.E.S.C. Regulation V-5 and SAE J684.

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.
Yes, the CURT 56325 is designed for the Cadillac XT5. The connector mounts behind the center of the rear bumper (S6 configuration) and connects to the vehicle's factory connector located in that area.
The CURT 56325 is compatible with GMC Acadia models, excluding the Limited trim. If you have an Acadia Limited, this connector is not compatible.
The CURT 56325 has signal circuits rated at 7.5 amps per side and tail/running circuits rated at 7.5 amps total. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower, as exceeding this can cause loss of warranty, overheating and potential fire.
Yes, you must disconnect the negative battery terminal before beginning installation. After completing all installation steps and reconnecting the connector, reconnect the negative battery terminal.
You will need a wire cutter. The manual does not list any other specialized tools as required.
The vehicle connector is located behind the rear bumper in the center of the vehicle. It will be similar in appearance to the CURT wiring connector. Take care not to damage the locking tabs when separating the vehicle connectors from the weather seal connectors.
Insert the CURT wiring connector end into the vehicle connector. Make sure the connectors are fully inserted with the locking tabs in place. Do not force the connection; it should seat fully when properly aligned.
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 to prevent damage and keep the connector organized.
Yes, install the provided 4-flat dust cover after completing the installation. The dust cover helps prevent corrosion of the connector.
Test the connector for proper function using either a test light or by connecting a properly wired trailer. For the initial test, reset the vehicle's electrical system by temporarily removing the key from the ignition. All connections must be complete for the wiring harness to function properly.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Exceeding this limit can cause loss of warranty, overheating and potential fire. Refer to your vehicle owner's manual or contact the vehicle manufacturer for your specific lamp load rating.
Yes, the CURT 56325 fits Cadillac XT5 and GMC Acadia (excluding Limited). It mounts behind the center of the rear bumper.
Yes, disconnect the negative battery terminal before installation and reconnect it after all steps are complete.
Only a wire cutter is required.
Signal circuits: 7.5 amps per side. Tail/running circuits: 7.5 amps total. Do not exceed the product rating or your vehicle's lamp load rating, whichever is lower.
Exceeding the product rating or tow vehicle lamp load rating (whichever is lower) can cause loss of warranty, overheating and potential fire.
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.
