The 04-10 Infiniti QX56 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1494 (Part #HBCW1494) fits the following vehicles: 2004-2010 Infiniti QX56. Always verify your specific year, make, and model before ordering.
The 04-10 Infiniti QX56 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1494 (Part #HBCW1494) fits 2004-2010 Infiniti QX56 models. The 2010 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the 04-10 Infiniti QX56 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1494 (Part #HBCW1494) is designed to fit the 2004-2010 Infiniti QX56.
The 04-10 Infiniti QX56 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1494 (Part #HBCW1494) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
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.
Gross trailer weight (GTW) is 6,000 lbs. with a tongue weight (TW) of 900 lbs. Weight distribution capacity is 6,000 lbs. with a weight distribution tongue weight (WDTW) of 900 lbs.
Required tools: ratchet, 3/4" socket, 21mm socket, 6" socket extension, torque wrench, marker, tape measure, utility knife, exhaust removal tool, and safety glasses.
Yes. The exhaust pipe must be lowered and three exhaust hangers must be removed. The exhaust must be supported before removing the rubber hangers, then reinstalled after hitch mounting.
Yes. The bumper cover must be trimmed. Measure a 4.25" wide and 2.5" deep section in the center from the lowest edge, mark it, and use a utility knife to cut the lower fascia.
All M12 fasteners must be torqued to 60 ft-lbs.
Yes, the spare tire must be temporarily removed to access the hitch mounting area. Use a 21mm socket to lower the spare tire. After hitch installation, push the spare tire slightly forward to add clearance from the receiver.
Safety glasses must be worn at all times during installation. Be careful when cutting plastic or metal as injury may occur if done improperly. Support the exhaust before removing rubber hangers.
The kit includes 6 hex head cap screws (M12) and 6 conical-toothed washers (M12). These fasteners are used to secure the hitch to the vehicle frame.
Open the rear hatch to access the spare tire lift mechanism. Use a 21mm socket to lower the spare tire and set it aside during installation.
Measure a 4.25" wide and 2.5" deep section in the center from the lowest edge of the bumper cover. Mark the section and use a utility knife to cut the lower fascia. Center align the cut.
The conical-toothed washers must be oriented with the teeth facing the vehicle frame. Refer to the assembly diagram on page 2 for the correct orientation of the washer between the hex bolt and hitch side plate.
No. In Step 4, loosely install the M12 bolts and conical washers to secure the hitch to the vehicle. Only after the exhaust and spare tire are reinstalled should you torque all M12 fasteners to 60 ft-lbs. in Step 5.
After loosely installing the hitch and torquing all M12 fasteners to 60 ft-lbs., reinstall the exhaust pipe first, then reinstall the spare tire. Push the spare tire slightly forward to add clearance from the receiver.
Never exceed the vehicle manufacturer's recommended towing capacity. The CURT 13512 has a gross trailer weight capacity of 6,000 lbs. and tongue weight of 900 lbs., but your vehicle's manufacturer may have a lower limit that must be observed.
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.
An exhaust removal tool (exhaust removal pliers) is required. Apply soapy water to help lower the exhaust pipe and remove the three exhaust hangers.
Use a utility knife to cut the lower fascia. Be careful when cutting plastic or metal as injury may occur if done improperly. Wear safety glasses during this step.
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.
Part number 56520 is designed for SUVs and Vans (S). The manual shows a representative vehicle but does not list specific makes, models, or model years. Consult the product fitment database or contact Curt Manufacturing to confirm compatibility with your specific vehicle.
The kit includes a harness with a blue relay, a 4-flat connector, cable ties for securing wires, and a 4-flat dust cover. The manual does not provide a complete itemized parts list, so verify all components are present before beginning installation.
Yes. Step 1 requires you to disconnect the negative battery terminal before beginning installation. Fasten this wire down and away from the battery during the installation process.
You will need a panel trim removal tool and a 10mm socket. The manual rates installation difficulty as 'Easy' and notes that proper tools will improve installation quality and reduce time required.
Yes. Step 2 requires you to open the rear hatch, lay the rear seats down, and remove the floor board to gain access to the storage area where the harness will be routed.
The white housing is located on the sidewall of the cargo area. Install the harness with the blue relay in this housing and secure it with a zip tie to prevent rattling or noise caused by vibration.
The 4-flat connector mounts near the receiver tube, accessed from under the passenger side or center of the rear bumper. Locate the housing with a dust cover plug, remove the plug, insert the connector, and secure excess wire with cable ties to keep it out of the way.
1. Disconnect the negative battery terminal. 2. Open the rear hatch and remove the floor board. 3. Use a panel trim removal tool to loosen push fasteners on the back-trim flap, threshold trim, and cargo bin. 4. Use a 10mm socket to loosen three screws and remove the cargo bin. 5. Remove the cargo hold-down and loosen sidewall trim. 6. Install the harness with blue relay in the white housing on the sidewall and secure with a zip tie. 7. Install the 4-flat connector near the receiver tube under the rear bumper and secure with cable ties. 8. Test the harness and reconnect the battery.
Use zip ties to secure the harness with the blue relay in the white housing on the sidewall, and use cable ties to secure excess wire near the 4-flat connector to keep it out of the way and prevent vibration noise.
A 10mm socket is required. Step 4 specifies using a 10mm socket to loosen the three screws in the bottom of the cargo bin. The manual does not provide a specific torque value for these screws.
A 10mm socket is required to remove the cargo hold-down on the driver side during Step 5 of the installation.
Do not lay tools across the positive battery terminal (typically noted with red covers or a red '+' symbol). This can cause a ground short, resulting in sparks and/or electrical shocks.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding either rating may cause unsafe operation or damage.
After reconnecting the negative battery terminal, test the harness using a test light, 4-flat tester, or a functioning trailer to verify proper operation.
Reinstall all items removed during installation, including the floor board, rear seats, cargo bin, cargo hold-down, and all trim pieces. Install the provided 4-flat dust cover to help prevent corrosion.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. The manual does not specify an inspection interval.
Using a panel trim removal tool, loosen and remove: the push fasteners covering the back-trim flap of the rear seat, the threshold trim between the hatch and cargo bin, the push fasteners securing the cargo bin, the trim cover of the cargo hold-down on the driver side, and the push fasteners on the sidewall trim on the driver side.
