The 19-24 Mazda 3 Sedan CURT 4-flat Plug and Play Trailer Wiring (Part #CTW1762) fits the following vehicles: 2019-2024 Mazda 3. Always verify your specific year, make, and model before ordering.
The 19-24 Mazda 3 Sedan CURT 4-flat Plug and Play Trailer Wiring (Part #CTW1762) fits 2019-2024 Mazda 3 models. The 2024 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the 19-24 Mazda 3 Sedan CURT 4-flat Plug and Play Trailer Wiring (Part #CTW1762) is designed to fit the 2019-2024 Mazda 3.
The 19-24 Mazda 3 Sedan CURT 4-flat Plug and Play Trailer Wiring (Part #CTW1762) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes. The 56435 is designed for both sedan and hatchback passenger cars with 12-volt negative ground electrical systems. Installation steps differ between body styles: hatchbacks follow steps 3A through 7A, and sedans follow steps 3B through 7B. Consult your vehicle owner's manual to confirm your vehicle has a 12-volt negative ground system before purchasing.
No. The converter system is designed only for 12-volt negative ground systems. Do not use on 24-volt systems or vehicles with positive ground electrical systems. Check your vehicle owner's manual to confirm the electrical system type before installation.
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 the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
Required tools are: ratchet, panel trim removal tool, 10 mm socket, socket extension, cutting tool, wire crimper, wire stripper, flathead screwdriver, and electrical tape. Proper tools will improve installation quality and reduce installation time.
Yes. Disconnect the negative battery terminal before beginning installation. Fasten this wire down and away from the battery during the installation process. Reconnect the negative battery terminal only after all other installation steps are complete and before testing the harness.
Open the vehicle trunk and remove the floor covering, rear cargo area cover, and both side covers. Remove the fasteners securing the rear scuff panel, then remove the scuff panel by pulling out on the bottom and then up. Take care not to damage the alignment tabs on the back.
The custom wiring end with the yellow wire connects between the separated driver-side taillight connectors. The custom wiring end with the green wire connects between the separated passenger-side taillight connectors. Both connectors must be fully inserted with locking tabs in place. Take care not to damage the locking tabs when separating the original connectors.
On the driver side, locate a flat spot behind the trunk liner. Adhere the black converter box using the provided double-sided tape. Ensure the surface is clean and dry before applying the tape for best adhesion.
12 gauge (12 GA) wire or larger is used for the power lead from the vehicle battery to the converter. Route this wire to the vehicle battery location, taking care to avoid pinch points and hot or rotating components.
A 15-amp maximum fuse is required. The battery connection must be fuse-protected with a 15-amp fuse holder. Install the fuse after all other installation steps are complete. Exceeding this fuse rating can cause loss of warranty, overheating, and potential fire.
Green = Right turn; Red = Brake; Yellow = Left turn; Brown = Taillight. These wires connect to the corresponding vehicle taillight circuits. If using the converter as a powered module for a two-wire system, the red brake wire must be grounded.
Attach the ring terminal of the white ground wire to the vehicle body using the screw provided. Drill a 3/32-inch hole if necessary. Ensure a clean, bare metal connection for proper grounding.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. When in use, route the 4-flat to the center of the vehicle and out of the trunk. Install the provided 4-flat dust cover to help prevent corrosion.
When passing the power wire through sheet metal, use an existing grommet, add a new grommet, or use silicone to protect the power wire from sharp edges. This prevents the wire from being damaged and causing electrical shorts or fire.
Secure any loose wires with the provided cable ties. Route the black power wire to the vehicle battery location using cable ties to secure it to the vehicle chassis, keeping it away from pinch points and hot or rotating components.
Once the 12-volt power wire is connected to the harness, verify that the harness is functioning by attaching the battery and testing with a test light, 4-flat tester, or a functioning trailer. This confirms all circuits are working before final use.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. Check the 4-flat connector dust cover regularly to ensure it is in place and preventing corrosion.
The kit includes the custom wiring harness with yellow, green, red, and brown signal wires; a black converter box; a white ground wire with ring terminal; a black power wire; a 4-flat connector with dust cover; double-sided tape for mounting the converter box; cable ties for securing wires; a fuse holder with 15-amp fuse; and a mounting screw for the ground wire.
The 56435 fits passenger cars (sedans and hatchbacks) with 12-volt negative ground electrical systems. Check your vehicle owner's manual to confirm your electrical system type. Different installation steps apply to sedans versus hatchbacks.
You will need: ratchet, panel trim removal tool, 10 mm socket, socket extension, cutting tool, wire crimper, wire stripper, flathead screwdriver, and electrical tape.
Yes, disconnect the negative battery terminal before starting installation. Reconnect it only after all other steps are complete and before testing.
A 15-amp maximum fuse is required for the battery connection. Install the fuse after all other steps are complete.
12 gauge (12 GA) wire or larger is used for the power connection from the vehicle battery to the converter.
First, verify that the 12-volt power wire is properly connected to the positive battery terminal through the 15-amp fuse holder, and that the white ground wire is securely attached to the vehicle body with good metal-to-metal contact. Confirm that the yellow wire is fully inserted with locking tabs in place at the driver-side taillight connector, and the green wire is fully inserted at the passenger-side taillight connector. Test using a test light, 4-flat tester, or functioning trailer. Check that the negative battery terminal is reconnected. Inspect all wires and connections for visible damage or loose connections.
The manual warns to take care not to damage the locking tabs when separating the original taillight connectors from the taillight housing. If tabs are damaged, the connectors may not stay fully inserted, causing intermittent or complete loss of function. Consult the vehicle manufacturer or a professional installer for repair or replacement of the damaged connector assembly, as the manual does not provide a repair procedure.
