The 03-08 Hyundai Tiburon 1.25 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1454 (Part #HBCW1454) fits the following vehicles: 2003-2008 Hyundai Tiburon. Always verify your specific year, make, and model before ordering.
Yes, the 03-08 Hyundai Tiburon 1.25 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1454 (Part #HBCW1454) is designed to fit the 2003-2008 Hyundai Tiburon.
The 03-08 Hyundai Tiburon 1.25 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1454 (Part #HBCW1454) fits 2003-2008 Hyundai Tiburon models. The 2008 model year is the last year covered by this part number. For newer models, check for an updated version.
The 03-08 Hyundai Tiburon 1.25 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1454 (Part #HBCW1454) 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.
The gross trailer weight (GTW) capacity is 3,500 lbs, with a tongue weight (TW) capacity of 525 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
The manual does not specify vehicle make, model or year compatibility. Contact CURT product support at 877.287.8634 or visit curtmfg.com to confirm fitment for your vehicle.
You will need a ratchet, torque wrench, 14mm socket, 17mm socket, flathead screwdriver, and wire brush. A tools reference guide is available at curtmfg.com/trailer-hitch-installation.
Yes, you must remove the underbody panel. Use a flathead screwdriver to remove four push fasteners, then use a 14mm socket to loosen three nuts. Return the panel and fasteners to the vehicle owner.
All M10 bolts must be tightened to 48 ft-lbs.
The manual notes that lowering the exhaust may be needed to ease installation, but does not state whether it is required. If you encounter interference, lower the exhaust as needed.
Yes. CURT stands behind its products with industry-leading warranties. To get copies of the product warranty, register your purchase, or provide feedback, visit warranty.curtgroup.com/surveys.
The kit includes six M10 x 1.25–35mm hex bolts (Class 10.9) and six 7/16" conical-toothed washers. These are the only fasteners supplied; the hitch bolts to existing vehicle frame weldnuts.
The conical-toothed washers must be oriented correctly under the hex bolts. Refer to the weldnut cleaning diagram on page 2, which shows the proper orientation of the conical-toothed washer between the hex bolt and the hitch side plate.
Raise the hitch into position and loosely secure it with all six M10 bolts and six conical-toothed washers first. Once the hitch is positioned correctly, tighten all M10 bolts to 48 ft-lbs.
To remove debris from weldnuts, spray lubricant or compressed air into the hole. For heavy debris, use a wire brush. Take care not to damage the threads.
Safety glasses must be worn at all times while installing this product. Never exceed your vehicle manufacturer's recommended towing capacity. Before beginning installation, read all instructions thoroughly.
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 installation is rated as Easy. However, installation difficulty levels are based on time and effort involved and may vary depending on the installer's level of expertise, the condition of the vehicle, and whether proper tools and equipment are available.
CURT part 56420 is designed for SUVs and vans classified as S-series vehicles. The manual does not list specific vehicle makes, models, or years. Contact CURT or consult a fitment database to confirm compatibility with your exact vehicle before purchasing.
CURT 56420 is a custom wiring harness for SUVs and vans that connects the vehicle's factory electrical system to a trailer connector. It includes a converter box, 4-flat connector, fuse holder, and cable ties. The harness allows you to power trailer lights and signals from your vehicle's existing lighting circuits.
You will need: a ratchet, a 14mm socket, a socket extension, a panel trim removal tool, and a cutting tool. These are the minimum tools required for installation.
Yes. Step 1 requires you to locate the vehicle battery on the driver side in the engine compartment and disconnect the negative terminal. Fasten this wire down and away from the battery during installation. Reconnect it in Step 5 after all other work is complete.
The battery connection must be fuse-protected with a maximum of 15 amps. The fuse is provided in the kit and must be installed into the fuse holder in the custom wiring harness during Step 3. Exceeding this rating can cause loss of warranty, overheating, and potential fire.
The manual does not provide a specific torque value for the 14mm bolts. It states only that the 14mm nuts on the shroud are push nuts and should be tightened so they do not cause noise. Contact CURT for the exact torque specification.
Signal circuits are rated at 5.0 amps per side. Tail and running circuits are rated at 7.5 amps total. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
The wiring harness is installed behind the driver side rear bumper (location S5). The converter box is adhered to a flat spot near the factory harness area using provided double-sided tape. The 4-flat connector is routed along the back of the vehicle to the hitch.
In Step 3, remove the dust cover from the harness without damaging the locking tabs. Insert the custom wiring harness end into the OEM (factory) harness. Make sure the connectors are fully inserted with locking tabs in place. Then install the provided fuse into the fuse holder in the custom wiring harness.
In Step 2, locate the plastic shroud below the driver-side rear bumper cover. Remove three push fasteners and two 14mm bolts (which are attached to the shroud). These bolts are push nuts and should be tightened so they do not cause noise when reinstalled.
In Step 4, route the 4-flat connector along the back of the vehicle to the hitch. Secure any loose wires with the provided cable ties to prevent movement and damage.
The black converter box is part of the CURT 56420 harness assembly. In Step 4, locate a flat spot near the factory harness area and adhere the converter box using the provided double-sided tape. This box converts the vehicle's factory lighting signals to the 4-flat trailer connector format.
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. After disconnecting the negative terminal in Step 1, fasten this wire down and away from the battery during the entire installation.
After installation, test for proper function by using a test light or connecting a properly wired trailer. This will verify that all signal and running circuits are functioning correctly before towing.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. Install the provided 4-flat dust cover to help prevent corrosion.
The kit includes a custom wiring harness with connector, a converter box, a 4-flat connector with dust cover, a fuse (15-amp max), a fuse holder, double-sided tape, and cable ties. All components are needed for proper installation.
CURT 56420 is designed for SUVs and vans (S-series vehicles). Consult a fitment database or contact CURT to confirm compatibility with your specific vehicle make, model, and year.
Yes. Disconnect the negative battery terminal before starting installation and reconnect it after all work is complete.
No drilling is required. The converter box is adhered using provided double-sided tape, and the harness connects to the factory connector without drilling.
Do not exceed the product rating or tow vehicle lamp load rating. Do not lay tools across the positive battery terminal, as this can cause sparks or electrical shocks.
Periodically inspect all wires and connections for visible damage or loose connections. Install the provided 4-flat dust cover to prevent corrosion.
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.
