Yes, the 24-24 Lexus TX550h+ 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1718 (Part #HBCW1718) is designed to fit the 2024 Lexus TX550h+.
The 24-24 Lexus TX550h+ 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1718 (Part #HBCW1718) fits 2024 Lexus TX550h+ models. The 2024 model year is the last year covered by this part number. For newer models, check for an updated version.
The 24-24 Lexus TX550h+ 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1718 (Part #HBCW1718) fits the following vehicles: 2024 Lexus TX550h+. Always verify your specific year, make, and model before ordering.
The 24-24 Lexus TX550h+ 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW1718 (Part #HBCW1718) 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.
Curt part 55245 is designed for Lexus LX 470, Lexus RX 300, Toyota 4Runner, Toyota Highlander, and Toyota Landcruiser. Verify your vehicle model matches this list before purchasing.
The manual does not specify what components are included in the kit. Contact Curt Manufacturing or your retailer for a complete parts list.
The factory tow plug is located behind the bumper (marked as S6). On some vehicles, the tow plug may be hidden under a black box cover secured with 10 mm hex bolts. Remove these bolts to access the plug.
You will need a 10 mm hex wrench or socket to remove the bolts securing the black box cover (if present on your vehicle). A 20 amp fuse is required for Highlander and RX300 models.
Insert the harness connector into the vehicle's factory harness connector (located at S6 behind the bumper). Route the 4-flat connector to the center of the vehicle and secure it in a convenient, out-of-the-way location.
A 20 amp fuse is required for Lexus RX300 and Toyota Highlander models. Locate the fuse panel on the driver's side of the engine compartment and insert the fuse in the location marked 'towing'. Other vehicles in the compatibility list may not require this step; consult your vehicle's manual if uncertain.
Before drilling, verify that no miscellaneous items (wiring, fuel lines, brake lines, etc.) are hidden behind or under any surface where you plan to drill. Drilling into hidden components can cause damage and personal injury.
Yes, if you own a Lexus LX 470, RX 300, or a Toyota 4Runner, Highlander, or Landcruiser. Other models are not compatible.
A 10 mm hex wrench to remove the black box cover (if present), and a 20 amp fuse for Highlander and RX300 models.
The manual does not specify whether professional installation is required or recommended. Contact Curt Manufacturing or a qualified installer if you are unsure about performing the installation yourself.
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.
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.
The 13519 has a gross trailer weight (GTW) capacity of 5,000 lbs and a tongue weight (TW) capacity of 500 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
The kit includes 4 hex bolts (M12) and 4 conical-toothed washers (1/2"). These fasteners are used to secure the hitch to the vehicle frame weldnuts.
You will need: ratchet, flathead screwdriver, 19mm socket, safety glasses, and a torque wrench. A tools reference guide is available at curtmfg.com/trailer-hitch-installation.
Yes. Use a flathead screwdriver to remove the two plastic weldnut plugs on the outer side of the frame rail on both sides of the vehicle. Return the plugs to the vehicle owner after installation.
To remove debris from weldnuts in the frame, spray lubricant or compressed air into the hole. For heavy debris, use a wire brush. Take care not to damage the threads.
1. Remove the two plastic weldnut plugs from the frame rails using a flathead screwdriver. 2. Raise the hitch into position and align the mounting holes with the weldnuts in the frame. 3. Loosely install the hex bolts and conical-toothed washers. 4. Torque all hardware to 86 ft-lbs.
Yes. Loosely install the supplied hex bolts and conical-toothed washers first to align the hitch properly with the frame weldnuts. Only after alignment is complete should you torque all hardware to the final specification of 86 ft-lbs.
All hardware on the 13519 must be torqued to 86 ft-lbs.
The hitch uses four M12 hex bolts to secure it to the vehicle frame weldnuts.
The hitch uses four 1/2" conical-toothed washers. These washers must be oriented correctly under the bolt heads to ensure proper clamping force.
The conical-toothed washers must be installed with the toothed side facing the hitch side plate. The assembly diagram on page 2 shows the correct orientation: the washer sits between the hex bolt head and the hitch mounting surface.
Safety glasses must be worn at all times while installing this product. Additionally, never exceed your vehicle manufacturer's recommended towing capacity when using the hitch.
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 and vehicle.
