The 07-19 Toyota Yaris Hatchback 1.25 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW2461 (Part #HBCW2461) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, CURT hitch 11421 is designed for 2016-Present Scion iA and Toyota Yaris iA sedans. Verify your vehicle matches this model and body style before purchasing.
The hitch is rated for a maximum trailer weight of 2000 lbs and tongue weight of 200 lbs when used as a weight-carrying hitch. Never exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
Non-trailer (wheel-less) loads can be applied to this hitch only if they are supported by CURT 18050 stabilizing straps. Failure to use stabilizing straps for non-trailer loads will void the product warranty. Consult the CURT catalog or www.curtmfg.com for stabilizing strap information.
CURT hitch 11421 is designed for use with ball mount #45520. Euro mount options are available: #45561 (1 7/8" ball) and #45562 (2" ball).
Required tools are: 11/16" socket, 6" socket extension, ratchet, torque wrench, die grinder, panel removal tool, and safety glasses. A die grinder is needed to enlarge the access hole on the passenger side frame rail.
The kit includes: 4× 7/16-14 UNC carriage bolts (part 10-10282), 4× .250 x 1.00 x 2.50" square hole spacers (CM-SP11), 4× 7/16-14 UNC serrated flange nuts (part 20-00103), and 4× 7/16" fishwires (part 7_16 FISHWIRE).
Yes. Step 1 requires disconnecting three electrical harness pins from the driver side frame rail using a panel removal tool. The harness is reconnected in step 6 through the clearance hole on the driver side frame rail after the hitch is secured.
No drilling is required. However, the access hole on the passenger side frame rail must be enlarged using a die grinder to allow 7/16" carriage bolts and CM-SP11 spacers to pass through. The driver side frame rail uses existing holes.
Fishwires are used to guide the 7/16" carriage bolts and spacers through the frame rail access holes and mounting holes. The fishwires are attached to the bolts, pulled through the holes to guide them into position, then removed before the flange nuts are installed. Keep fishwires attached to prevent loss into the frame rails.
Two people may be required to ease installation. While one person may be able to complete the installation, having a second person will improve the quality of the install and reduce installation time.
All 7/16" hardware (carriage bolts and flange nuts) must be torqued to 70 ft-lbs. Use a torque wrench to ensure proper tightening.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This ongoing inspection helps maintain the integrity and safety of the installation.
Safety glasses must be worn at all times while installing this product. Before beginning installation, read all instructions thoroughly. If you are hesitant to undertake this task, contact an authorized CURT installer for assistance. Technical support is available at 877.287.8634.

Maximum trailer weight 2000 lbs, tongue weight 200 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
No drilling required. You must enlarge the passenger side frame rail access hole with a die grinder to fit the 7/16" bolts and spacers.
11/16" socket, 6" socket extension, ratchet, torque wrench, die grinder, panel removal tool, and safety glasses.
All 7/16" bolts and nuts must be torqued to 70 ft-lbs.
You must disconnect three electrical harness pins from the driver side frame rail before installation using a panel removal tool. Reconnect after securing the hitch.
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 56311 is designed for Scion iA and Toyota Yaris iA sedan models. The harness is a passenger car installation (type P) with connectors located behind the driver and passenger side taillights inside the trunk.
The harness is rated for 3.0 amps per side on signal circuits and 6.0 amps total on tail/running circuits. The battery connection must be fuse-protected with a maximum 10-amp fuse. Do not exceed the product rating or your vehicle's lamp load rating, whichever is lower, as exceeding it can cause loss of warranty, overheating and potential fire.
You will need a panel trim removal tool, wire stripper, wire crimper, and cutting tool. These are standard automotive electrical installation tools and are not included with the harness.
Yes. The first step of installation is to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal. This is a required safety step before beginning any wiring work.
The connectors are located behind the taillight housing inside the trunk. On the driver side, they are behind the driver side taillight (P3 location). On the passenger side, they are behind the passenger side taillight (P4 location). You access them by removing the trunk floor coverings, rear scuff panel, and side trim panels.
Insert the custom wiring harness end with yellow, brown and red wires between the separated vehicle taillight connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat the process on the passenger side using the harness end with the green wire. Take care not to damage the locking tabs during insertion.
Drilling may be required for the ground wire installation. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, you will need to drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.
Drill a 3/32" pilot hole for the provided ground screw. The grounding point should be free of rust, dirt and paint, and located near the taillight connector.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame, or drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The exact location should be chosen to keep the box secure and out of the way.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties to prevent tangling and damage.
After installation, reinstall all items removed during the install, including trunk floor coverings, scuff panel and side trim panels. Install the provided 4-flat dust cover to help prevent corrosion. Test the harness for proper function by using a test light or connecting a properly wired trailer.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or your tow vehicle lamp load rating, whichever is lower.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. This is especially important when drilling the 3/32" pilot hole for the ground wire screw.
The harness has yellow, brown, red, green and white wires. The yellow, brown and red wires connect to the driver side taillight connectors. The green wire connects to the passenger side taillight connectors. The white wire is the ground wire, which must be secured to a grounding point using the provided ring terminal and screw.
Remove the two push fasteners securing the rear scuff panel. Remove the scuff panel by pulling out on the bottom and then up. Take care not to damage the alignment tabs on the back of the panel, as these are needed for proper reinstallation.
Starting on the driver side, remove the push fasteners from the side trim panel. Pull back the side trim panel to locate the vehicle taillight wiring harness connectors. Repeat this process on the passenger side after routing the harness to that side.
Open the vehicle trunk and remove all trunk floor coverings. These must be removed to access the rear scuff panel and side trim panels. Reinstall them after completing the wiring harness installation.
Yes, the Curt 56311 is designed specifically for Scion iA and Toyota Yaris iA sedan models.
You need a panel trim removal tool, wire stripper, wire crimper, and cutting tool.
Drilling may be required for the ground wire installation. You may need to drill a 3/32" pilot hole if no existing screw is available at the grounding point.
The battery connection must use a maximum 10-amp fuse. Exceeding this can cause overheating and fire.
Signal circuits are rated for 3.0 amps per side; tail/running circuits are rated for 6.0 amps total. Do not exceed these ratings or your vehicle's lamp load rating.
Test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the harness functions properly.
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.
