Yes, the 19-24 Ford Edge CURT 4-flat Plug and Play Trailer Wiring (Part #CTW808) is designed to fit the 2019-2024 Ford Edge.
The 19-24 Ford Edge CURT 4-flat Plug and Play Trailer Wiring (Part #CTW808) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The CURT 56437 is a powered converter harness designed for SUVs and vans. It converts the vehicle's factory taillight signals into a 4-flat trailer connector, allowing you to tow a trailer with proper lighting control. The system includes a converter box that processes brake, turn signal, and taillight signals from your vehicle's rear lights.
The CURT 56437 is designed for SUVs and vans with 12-volt negative ground electrical systems. The manual does not list specific vehicle models or years. Check your vehicle owner's manual to confirm it has a 12-volt negative ground system, or contact the vehicle manufacturer. The wiring locations shown in the manual are representative; actual locations may vary by vehicle.
No. The converter system is designed only for 12-volt negative ground systems. It will not function on 24-volt systems or vehicles with positive ground electrical systems.
Required tools are: ratchet, cutting tool, socket extension, wire crimper, Torx bit T-25, wire stripper, small flathead screwdriver, panel trim removal tool, and flathead screwdriver. You will also need a pry tool (not listed but referenced in Steps 3 and 4) and a fish wire or equivalent (cut-up wire hanger, stiff wire, rope or string) to route wires through blind holes.
The kit includes: a black converter box, a T-connector with yellow wire, a green wire for passenger-side routing, a black power wire, a white ground wire with ring terminal, a provided screw for grounding, double-sided tape for mounting the converter box, a 4-flat dust cover, zip ties for securing loose wires, and a 15-amp fuse holder with fuse. Butt connectors are referenced in the wiring diagram.
Yes. You must disconnect the negative battery terminal before beginning installation. Fasten this wire down and away from the battery during the installation. Reconnect the negative battery terminal only after all other installation steps are complete and before testing the harness.
The installation is rated as moderate difficulty. The manual states that proper tools will improve the quality of installation and reduce the time required. All steps must be followed to ensure the product functions properly. No specific installation time is provided.
Step 1 is to locate the vehicle battery on the driver side in the engine compartment and disconnect the negative terminal. Fasten this wire down and away from the battery during the installation.
Using a pry tool and being careful not to dent or scratch the vehicle, loosen the taillight and pull rearward to remove. Behind the taillight, locate the vehicle taillight wiring harness connectors. Disconnect the housing by releasing the locking tabs. Set the taillight to the side. Repeat this process on both the driver and passenger sides.
Fish wire is used to push or pull the electrical harness through blind holes (holes you cannot see through). You insert the fish wire through the blind hole, locate it on the other side, use tape to secure the harness to the fish wire, and pull it back up. Fish wire can be a cut-up wire hanger, stiff wire, rope or string. If the wire gets hung up, you may need to push back down, wiggle it around, or twist it to loosen it.
Locate a flat clean surface that is out of the path of spray and debris from the rear wheels and road. Adhere the black converter box using the provided double-sided tape. Mounting the box in a protected area is critical—failure to do so can cause loss of warranty, product failure, overheating and potential fire.
You need to locate a suitable grounding point near the converter box, such as an existing screw with nut in the vehicle frame. If no existing screw is available, you may drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
When passing the power wire through sheet metal, use an existing grommet, add a 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.
The battery connection must be fuse-protected with a 15-amp maximum fuse. Do not exceed this rating. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
Signal circuits (turn signals): 5.0 amps per side. Tail/Running circuits: 7.5 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Use 12 GA (12-gauge) wire or larger for the power wire from the vehicle battery to the converter. The manual specifies routing 12 GA wire to the vehicle battery location.
The wire colors are: Green = Right turn signal, Red = Brake, Yellow = Left turn signal, Brown = Taillight. These colors correspond to the trailer lighting functions controlled by the converter.
On the driver side under the vehicle, find the fish wire and secure the T-connector end with the yellow wire to it. Pull the T-connector end up to the taillight pocket. Install the connector onto the factory wiring to keep it from falling down. Make sure the connectors are fully inserted with locking tabs in place.
Route the green wire to the passenger side, up and out of the way. Use the fish wire method (Step 5) to route the green wire to the passenger-side taillight pocket, similar to how the yellow wire is routed on the driver side.
Route the trailer 4-flat connector to the center of the vehicle and mount it near the hitch. Secure any loose wires with the provided zip ties.
Route the black power wire from the vehicle battery as shown on the last page of the manual (page 5). The black wire connects to the positive (+) battery terminal using a ring terminal. The wire must be 12 GA or larger and routed to avoid pinch points and hot or rotating components. Secure the power wire to the vehicle chassis using the provided cable ties.
Attach the ring terminal of the white ground wire to the vehicle body using the provided screw. Locate a suitable grounding point near the converter box, such as an existing screw with nut in the vehicle frame. If necessary, drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint before securing the ground wire.
Before drilling or routing wires, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. When routing the power wire, avoid pinch points and hot or rotating components. Use a pry tool carefully to avoid denting or scratching the vehicle. Disconnect the negative battery terminal before beginning installation. When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the wire from sharp edges.
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. Reinstall all items removed during installation and reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion.
After installation is complete: (1) Verify the harness is functioning using a test light, 4-flat tester, or functioning trailer. (2) Reinstall all items removed during installation. (3) Reconnect the negative battery terminal. (4) Install the provided 4-flat dust cover to help prevent corrosion. (5) Install the 15-amp fuse in the fuse holder after all other steps are complete.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. The manual does not specify an inspection interval. For more detailed maintenance information, contact CURT Group or check the product warranty information at warranty.curtgroup.com/surveys.

Yes, disconnect the negative battery terminal before starting installation. Fasten the wire away from the battery. Reconnect it only after all installation steps are complete and before testing.
Drilling is optional. You only need to drill a 3/32" pilot hole if no existing screw with nut is available for grounding the converter box. Before drilling, check for hidden items behind or under surfaces to avoid damage.
The battery connection must use a 15-amp maximum fuse. Do not exceed this rating, as it can cause loss of warranty, overheating and potential fire.
Use 12 GA (12-gauge) wire or larger for the power wire from the vehicle battery to the converter.
