CURT part number 11389 is rated for a maximum of 2,000 lbs trailer weight and 200 lbs tongue weight when used as a weight-carrying hitch. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
CURT part number 11389 is designed for use with ballmount #45521, and with Euro ballmounts #45571 (1 7/8" ball) and #45572 (2" ball).
Required tools are: ratchet, 17mm socket, 12" socket extension, jack stands, wire pipe brush, aviation shears, and torque wrench. Safety glasses should be worn at all times during installation.
No, drilling is not required. CURT part number 11389 uses all existing vehicle fasteners (M12 weldnuts and bolts) for installation.
Two people may be required to ease installation, though the manual does not state this is mandatory. If you are hesitant to undertake the installation on your own, you can contact an authorized CURT installer for assistance.
Yes, the exhaust must be lowered during installation. You must remove (2) rubber isolators from the hanger bracket on each muffler and (2) forward center isolators, allowing the exhaust to hang below the frame rail. Support the exhaust from underneath. After the hitch is installed, the exhaust is raised back into position and all rubber isolators are reconnected.
1. Lower the exhaust by removing (2) rubber isolators from each muffler's hanger bracket and (2) forward center isolators; support exhaust from underneath. 2. Remove (6) hex flange bolts with a 17mm socket securing the exhaust hanger brackets and remove the brackets; save bolts and brackets. 3. Optionally trim heat shields about an inch forward by removing (4) nuts with a 10mm socket on each side. 4. Raise the hitch into position against the frame rails and reinstall the exhaust hanger brackets using the (6) M12 bolts. 5. Torque all M12 hardware to 79 ft-lbs, raise exhaust back into position, and reconnect all rubber isolators.
Yes, trimming the heat shields is optional. The heat shields on each side can be trimmed about an inch forward to clear the hitch side plates completely. To trim them, remove (4) nuts with a 10mm socket on both sides, trim the shields, and reinstall.
All M12 hardware must be torqued to 79 ft-lbs.
Never exceed your vehicle manufacturer's recommended towing capacity. While CURT part number 11389 is rated for 2,000 lbs trailer weight and 200 lbs tongue weight, your Lexus manufacturer's specifications may be lower and must be followed.
Safety glasses must be worn at all times while installing this product.
All non-trailer (wheel-less) loads applied to this product must be supported by CURT 18050 stabilizing straps. Failure to properly support non-trailer loads will void the product warranty. For further information, see the CURT catalog or visit www.curtmfg.com.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This should be done regularly to maintain safe operation.

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, Curt part 56142 is designed for Lexus IS 250 and Lexus IS 350 models. The T-Connector wiring harness integrates with the factory taillight connectors on both sides of the trunk.
The kit includes a T-Connector harness with yellow and green wire ends, a black converter box, a white ground wire with eyelet, double-sided tape, cable ties, a screw for grounding, and a 4-flat connector for use when needed. A separate CME-PCL-INS instruction sheet covers routing of the black power wire from the battery.
Open the trunk and remove: all trunk floor covers, the rear scuff panel (held by three plastic fasteners and cargo loops), and plastic fasteners holding the felt trunk liner in place on both sides. These items are reinstalled after installation.
On the driver's side, pull back the felt trunk liner to locate the factory taillight wiring harness connectors. Separate the connectors carefully without damaging the locking tabs. Insert the T-Connector end with the yellow wire between the separated connectors, ensuring both connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the T-Connector end with the green wire.
Locate a flat spot on the inside body panel of the vehicle behind the felt trunk liner near the connector. Adhere the black converter box using the double-sided tape provided.
Not necessarily. First, locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If no suitable point exists, drill a 3/32" hole and secure the eyelet of the white ground wire using the screw provided.
Route the T-Connector end with the green wire across to the passenger side behind the removed scuff panel. Use the cable ties provided to secure wires to an existing wiring harness. Route the 4-flat connector from under the felt trunk liner to the center of the vehicle and out of the trunk when in use. Roll up and store in an out-of-the-way location when not in use. Refer to the CME-PCL-INS instruction sheet for routing the black power wire from the battery to the converter.
Before drilling, verify that miscellaneous items hidden behind or under any surface will not be damaged. Drilling without checking can cause damage and/or personal injury.
When separating the factory taillight connectors, take care not to damage the locking tabs. The locking tabs must be in place when the T-Connector is fully inserted.
Yes, the Curt 56142 T-Connector is designed for Lexus IS 250 and IS 350 models.
Drilling is optional. A 3/32" hole is only needed if no suitable existing grounding point (screw with nut) is available in the vehicle's frame.
Basic hand tools for removing plastic fasteners and cargo loops, a screwdriver for the grounding screw, and optionally a drill with a 3/32" bit if a grounding hole is needed. Cable ties and double-sided tape are provided.
Remove all trunk floor covers, the rear scuff panel (three plastic fasteners and cargo loops), and plastic fasteners holding the felt trunk liner on both sides. All items are reinstalled after installation.
Locate the factory taillight connectors behind the felt trunk liner on each side. Separate them carefully without damaging the locking tabs. Insert the yellow-wire T-Connector end on the driver's side and the green-wire end on the passenger side between the separated connectors, ensuring full insertion with locking tabs in place.
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.
