Yes, the 11-14 Ford Mustang Convertible, excluding California Special 1.25 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW961 (Part #HBCW961) is designed to fit the 2011-2014 Ford Mustang.
The 11-14 Ford Mustang Convertible, excluding California Special 1.25 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW961 (Part #HBCW961) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, CURT 11048 is designed for 2010–2011 Ford Mustang Coupes. The installation procedure differs slightly between model years: 2010 models require rear exhaust hanger relocation, while 2011 models do not.
CURT 11048 is rated for a maximum trailer weight of 2,000 lbs and tongue weight of 200 lbs when used as a weight-carrying hitch. You must not exceed your vehicle manufacturer's recommended towing capacity.
The minimum tongue weight is 120 lbs.
The minimum trailer weight is 60 lbs.
Required tools are: pry bar, ratchet, 9/16" and 11/16" sockets (or 13 mm and 15 mm sockets), and a torque wrench. Safety glasses must be worn at all times during installation.
No, drilling is not required. The hitch uses fishwire hardware installation through existing access holes in the frame rails.
The manual does not specify whether the battery must be disconnected. Contact CURT Technical Support at 877-287-8634 for clarification.
Two people may be required to ease installation. The manual notes that using proper tools will greatly improve the quality of the install and reduce the time required.
The installation is rated as challenging. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance.
On 2010 models, the rear exhaust hangers must be removed and relocated. The exhaust pipes must be lowered by loosening the strap that fastens them together behind the muffler and detaching the pipes from each other. The rear of the muffler is then carefully lowered to hang from the remaining exhaust hanger. The four fasteners removed from the rear hangers should be returned to the vehicle owner. Alternatively, you may remove the forward exhaust hangers and remove the mufflers entirely, or leave the pipes attached and remove both sets of hangers (though this requires a vehicle lift).
On 2011 models, remove the rearmost rubber isolator on both mufflers. Lower the exhaust by loosening the strap that fastens the exhaust pipes together behind the muffler and detaching the pipes from each other. Carefully lower the rear of the muffler and let it hang from the remaining exhaust hanger. Repeat on the other side. Unlike 2010 models, the rear exhaust hangers do not need to be relocated.
Fishwire is a technique used to thread carriage bolts and spacers through access holes in the frame rails before raising the hitch into position. The bolts and spacers are inserted through the access holes and positioned so they are ready to receive the hitch when it is raised. This allows the hardware to be secured without drilling new holes.
The hitch is attached using carriage bolts, square hole spacers, round hole spacers, and serrated flange nuts. Specifically: 7/16 x 1" carriage bolts (part 10-10311, qty 2) with .250 x .88 x 2.25" square hole spacers (CM-SP2, qty 6); 7/16 x 1.5" carriage bolts (part 10-10282, qty 4) with .250 x .88 x 2.25" square hole spacers (CM-SP2); 3/8 x 2" carriage bolts (part 10-10323, qty 2) with .250 x 1.00 x 2.00" square hole spacers (CM-SP18, qty 2) and .500 x 1.25 x 2.50" round hole spacers (CM-SP52, qty 2) on 2010 models only. All bolts are Grade 8, and all nuts are serrated flange nuts.
Carriage bolts are installed using the fishwire technique. The bolts and spacers are threaded through access holes in the frame rails before the hitch is raised into position. Once the hitch is in place, the bolts are secured with flange nuts from the outside of the frame rail.
All 7/16" hardware on CURT 11048 must be torqued to 70 ft/lbs.
All 3/8" hardware on CURT 11048 must be torqued to 45 ft/lbs.
Fasteners are installed loosely during the initial assembly steps (steps 4–6). All fasteners are torqued to their final specifications only in the final step: 3/8" hardware to 45 ft/lbs and 7/16" hardware to 70 ft/lbs.
1. Remove the rearmost rubber isolator on both mufflers (2010 models: also remove and relocate rear exhaust hangers). 2. Lower the exhaust by loosening the strap connecting the exhaust pipes and detaching them. 3. Fishwire the shorter 7/16 x 1" carriage bolts and SP2 spacers through the access holes. 4. Raise the hitch into position and loosely attach with 7/16" flange nuts. 5. Fishwire the 7/16 x 1.5" carriage bolts and SP2 spacers and loosely attach with 7/16" flange nuts. 6. (2010 models only) Fishwire the 3/8 x 2" carriage bolts and SP18 spacers, add SP52 spacers and exhaust hangers, and secure with 3/8" flange nuts. 7. Torque all hardware and reinstall the exhaust.
Yes. 2010 models require removal and relocation of the rear exhaust hangers, and require additional 3/8" hardware (carriage bolts, spacers, and flange nuts) to secure the relocated exhaust hangers. 2011 models do not require exhaust hanger relocation. On the driver side of 2010 models, one additional 7/16 x 1.5" carriage bolt and SP2 spacer are installed in the lower hole on the outside of the frame rail.
All non-trailer (wheel-less) loads applied to CURT 11048 must be supported by 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.
Never exceed your vehicle manufacturer's recommended towing capacity. The hitch is rated for 2,000 lbs trailer weight and 200 lbs tongue weight, but your vehicle's manufacturer may specify a lower limit.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This maintenance is essential to safe operation.
CURT 11048 is designed for use with ballmount #55001 or #45501. Euro mount options are available: #45571 (1 7/8" ball) and #45572 (2" ball).

CURT 11048 complies with safety specifications and requirements for connecting devices and towing systems of the state of New York, V.E.S.C. Regulation V-5 and SAE J684.
Yes, CURT 11048 is designed for 2010–2011 Ford Mustang Coupes. Installation steps differ slightly between model years.
Pry bar, ratchet, 9/16" and 11/16" sockets (or 13 mm and 15 mm), torque wrench, and safety glasses.
Installation is rated challenging. Two people may be required. If hesitant, contact an authorized CURT installer.
Torque 7/16" hardware to 70 ft/lbs and 3/8" hardware to 45 ft/lbs. Tighten fasteners loosely during assembly, then torque to final specifications in the final step.
Periodically check that all fasteners are tight and all structural components are sound.
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.
Part 55326 is designed for Ford Crown Victoria, Ford Mustang (excluding Cobra SVT 99-04), and Mercury Grand Marquis. If your vehicle is one of these models, it will fit. For other vehicles or to confirm fitment on your specific year and model, check your vehicle owner's manual or contact the vehicle manufacturer.
The Curt 55326 is a custom wiring harness designed to connect your vehicle's taillight wiring to a 4-flat trailer connector. It allows you to safely tow a trailer by routing power from your vehicle's taillights through the harness to the trailer lights.
You will need a panel trim removal tool. This tool helps you safely remove the trunk scuff panel without damaging the alignment tabs. No other specialized tools are required for the basic installation.
Open the vehicle trunk. Remove the scuff panel by pulling out on the bottom and then up, taking care not to damage the alignment tabs on the back. Remove the plastic wing nuts securing the felt trunk liner. Pull back on the felt liner to locate the vehicle taillight wiring harness connectors behind the taillight housing.
Separate the vehicle taillight connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end (yellow wire for driver side, green wire for passenger side) between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process on both the driver and passenger sides.
Route the 4-flat connector to the center of the vehicle and out of the trunk when in use. When not in use, roll it up and store it in a convenient, out-of-the-way location inside the trunk.
Secure any loose wires with the provided cable ties. This helps prevent tangling, damage, and ensures a neat installation.
The harness includes cable ties for securing loose wires and a 4-flat dust cover to help prevent corrosion of the connector when not in use.
Do not exceed the product rating or your tow vehicle lamp load rating, whichever is lower. Exceeding the rating can cause loss of warranty, overheating, and potential fire. Consult your vehicle owner's manual or contact the vehicle manufacturer for your specific tow vehicle lamp load rating.
Test for proper function by using a test light or connecting a properly wired trailer. This confirms that the harness is correctly installed and all connections are secure before towing.
Yes. After routing and securing the wiring harness, reinstall all items removed during installation, including the felt trunk liner, plastic wing nuts, and scuff panel. Install the provided 4-flat dust cover to help prevent corrosion.
The harness has a yellow wire end and a green wire end. The yellow wire end connects to the driver side taillight housing (P3 location), and the green wire end connects to the passenger side taillight housing (P4 location).
The Curt 55326 fits Ford Crown Victoria, Ford Mustang (excluding Cobra SVT 99-04), and Mercury Grand Marquis. Check your vehicle owner's manual or contact the manufacturer to confirm your specific model year.
You need a panel trim removal tool to safely remove the trunk scuff panel. No other specialized tools are required.
Do not exceed the product rating or your tow vehicle lamp load rating, whichever is lower. Exceeding the rating can cause overheating and potential fire, and will void the warranty.
The harness includes cable ties for securing wires and a 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.
