The 18 - 20 Volkswagen Atlas CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK2465 (Part #7WK2465) fits the following vehicles: 2018-2020 Volkswagen Atlas. Always verify your specific year, make, and model before ordering.
Yes, the 18 - 20 Volkswagen Atlas CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK2465 (Part #7WK2465) is designed to fit the 2018-2020 Volkswagen Atlas.
The 18 - 20 Volkswagen Atlas CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK2465 (Part #7WK2465) fits 2018-2020 Volkswagen Atlas models. The 2020 model year is the last year covered by this part number. For newer models, check for an updated version.
The 18 - 20 Volkswagen Atlas CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK2465 (Part #7WK2465) 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 56383 is a powered converter lead and trailer wiring harness system designed for SUVs and vans. It converts the vehicle's taillight signals (left turn, right turn, brake, and tail/running lights) into a standard 4-flat trailer connector. The system includes a black converter box that processes the signals and a power lead that connects to the vehicle battery for operation.
CURT 56383 is designed for SUVs and vans with 12-volt negative ground electrical systems. The manual does not list specific vehicle makes, models, or years. Check your vehicle owner's manual to confirm it has a 12-volt negative ground system. For specific vehicle compatibility, contact CURT or consult a fitment database.
No. The manual explicitly states this converter system is to be used only on 12-volt negative ground systems. It is not compatible with 24-volt systems or positive ground vehicles.
Required tools are: ratchet, ratchet extension, socket (10mm), wire crimper, wire stripper, cutting tool, and panel trim removal tool. These tools are needed for removing interior panels, disconnecting the battery, crimping wire connections, and securing the harness.
The kit includes: a custom wiring harness with yellow, green, white, and black wires; a black converter box; a white ground wire with ring terminal; a provided screw for grounding; double-sided tape for mounting the converter box; cable ties for securing loose wires; a 4-flat dust cover; and a 15-amp fuse holder with 15-amp fuse.
Yes. Step 1 requires you to locate the vehicle battery and disconnect the negative battery terminal before beginning installation. Fasten this wire down and away from the battery. Reconnect it only after all other installation steps are complete and the fuse is installed.
The installation is rated as Moderate difficulty. The manual recommends reading all instructions thoroughly before beginning and notes that proper tools will improve installation quality and reduce time required.
For SUVs and vans, the taillight wiring harness connectors are located behind the interior side panels. The driver side connector is behind the driver side interior side panel (location S1 or S3 depending on access), and the passenger side connector is behind the passenger side interior side panel (location S2 or S4). You access these by removing the scuff panel and pulling out the interior side panels.
Locate the vehicle taillight wiring harness connectors. Separate the connector from the taillight housing by carefully removing the locking tabs. Insert the custom wiring harness end (yellow wire for driver side, green wire for passenger side) between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place. Repeat this process on both sides of the vehicle.
Mount the black converter box on a flat spot inside the vehicle near the taillight using the provided double-sided tape. The converter box should be positioned after routing the custom wiring harness end with the green wire down behind the interior side panel and out to the passenger side.
Route the black 12-gauge power wire from the vehicle battery to the converter, taking care to avoid pinch points and hot or rotating components. When the trailer is in use, route the 4-flat connector to the center of the vehicle and out of the trunk. When not in use, roll up and store the 4-flat in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Not necessarily. Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no suitable existing point is available, drill a 3/32" pilot hole for the provided screw. The grounding area should be free of rust, dirt, and paint. Always check for hidden items behind or under any surface before drilling to avoid damage and personal injury.
Drill a 3/32" pilot hole if a suitable existing grounding point is not available. This hole is for the provided screw that secures the white ground wire ring terminal to the vehicle frame.
Signal circuits (left turn, right turn): 5.0 amps per side. Tail/Running circuits: 7.5 amps total. The battery connection must be fuse-protected with a 15-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Use a 15-amp maximum fuse. The fuse holder with 15-amp fuse is provided in the kit. Install the fuse after all other installation steps are complete, including battery reconnection.
The power lead uses 12-gauge wire or larger. This wire connects from the vehicle battery to the converter system.
Yellow wire: Left turn signal. Green wire: Right turn signal. Red wire: Brake signal. Brown wire: Tail/running lights. White wire: Ground. Black wire: Power (connects to positive battery terminal). The yellow wire connects to the driver side taillight harness, and the green wire connects to the passenger side taillight harness.
Disconnect the negative battery terminal before wiring. Route the black 12-gauge power wire to the positive battery terminal using a ring terminal connector. Secure the ring terminal to the positive battery post. After all other installation steps are complete, install the 15-amp fuse in the fuse holder. Finally, reconnect the negative battery terminal.
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 faults or fire hazards.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. The battery connection must be fuse-protected with a 15-amp maximum fuse. Exceeding the product rating can cause loss of warranty, overheating, and potential fire. Additionally, always check for hidden items before drilling, and route the power wire to avoid pinch points and hot or rotating components.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. Install the provided 4-flat dust cover to help prevent corrosion.
After installation, test for proper function by using a test light or connecting a properly wired trailer. This verifies that all signal circuits (left turn, right turn, brake, and tail/running lights) are functioning correctly before towing.
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 and dust cover regularly, especially if the trailer is used frequently or stored in harsh conditions.
CURT 56383 is designed for SUVs and vans with 12-volt negative ground electrical systems. Confirm your vehicle has a 12-volt negative ground system in your owner's manual. For specific vehicle compatibility, contact CURT or consult a fitment database.
Yes, disconnect the negative battery terminal before starting installation. Reconnect it only after all other steps are complete and the fuse is installed.
Drilling is not always required. Use an existing screw with nut in the vehicle frame for grounding if available. If not, drill a 3/32" pilot hole for the provided ground screw. Always check for hidden items before drilling.
Use a 15-amp maximum fuse. The fuse holder with 15-amp fuse is included. Install the fuse after all other steps are complete.
The power lead uses 12-gauge wire or larger, connecting from the vehicle battery to the converter.
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.
