The 10-19 Lincoln MKT Excluding EcoBoost CURT 4-flat Plug and Play Trailer Wiring (Part #CTW1740) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The manual covers installation for the Lincoln MKT only. Compatibility with other vehicles is not documented in this manual. Contact Curt Manufacturing or consult a fitment database to confirm compatibility with your specific vehicle.
No. The converter system is designed only for 12 volt negative ground systems. Do not use it on any other electrical system configuration.
You will need an 8mm socket to remove the taillight housings. If you need to create a ground point, you will need a 3/32" drill bit. The manual does not specify other tools required for the installation.
The kit includes: a T-connector harness with yellow and green wire ends, a 4-flat connector, a black converter box, a white ground wire with eyelet and screw, double-sided tape, cable ties, and a fuse holder with 10 amp fuse (maximum). A ring terminal for battery connection is also shown in the wiring diagram.
Yes. You must disconnect the negative battery cable before wiring the power wire to the battery. This is a critical safety step to prevent electrical shock or short circuits during installation.
Open the rear hatch and remove both taillight housings by removing the screws on each using an 8mm socket. Pull out on the housing to locate the vehicle's taillight wiring harness, which will have connectors similar to those on the T-connector harness.
Separate the connectors on the driver's side, being careful not to damage the locking tabs. Insert the T-connector end with the yellow wire in-between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place.
Route the T-connector end with the green wire and the 4-flat down through the opening under the taillight. Under the vehicle, route the green wire across the backside of the bumper to the passenger side and up through the opening under the passenger side taillight. Then repeat the connection process on the passenger side using the green wire.
Adhere the black converter box to the frame of the vehicle using the double-sided tape provided. The exact location should be convenient and secure, away from moving parts and heat sources.
Locate a suitable grounding point near the converter box, 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 white ground wire using the eyelet and screw provided. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage or personal injury.
The wire colours represent the following functions: Green = Right turn, Red = Brake, Yellow = Left turn, Brown = Taillight. The yellow wire connects to the driver's side taillight harness, and the green wire connects to the passenger side.
Use 12 gauge wire or larger when routing the black power wire from the battery to the converter. The manual specifies 12 GA wire minimum for the battery connection.
Route the black 12 gauge power wire from the converter to the positive (+) battery terminal. Use a ring terminal for the battery connection. The negative battery cable must be disconnected before making this connection. After all other steps are complete, install the 10 amp fuse in the fuse holder.
The maximum fuse rating is 10 amps. Install the fuse after all other installation steps are complete.
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 safety hazards.
Secure any loose wires with the cable ties provided in the kit. Route the 4-flat connector to the center of the vehicle and secure it in a convenient, out-of-the-way location.
Secure the power wire to the vehicle chassis using the cable ties provided. Take care to avoid pinch points and hot or rotating components when routing the wire to the battery.
Before drilling any hole, verify that no miscellaneous items are hidden behind or under the surface where you plan to drill. This includes wiring, fuel lines, brake lines, or other components that could be damaged, causing personal injury or property damage.
If you need to drill a ground hole, the hole size is 3/32". Drill this hole only if a suitable existing ground point (such as a screw with nut in the vehicle frame) is not available.
Yes, the Curt 56095 is designed for the Lincoln MKT. It is a 12 volt negative ground system converter and requires access to the taillight housings and vehicle battery.
You need an 8mm socket to remove the taillight housings and a 3/32" drill bit if you need to create a ground point. All other hardware and fasteners are included.
Yes, disconnect the negative battery cable before wiring the power wire. This is essential for safety.
Use 12 gauge wire or larger for the battery connection. The maximum fuse rating is 10 amps. Install the fuse after all other steps are complete.
Before drilling, verify that no miscellaneous items (wiring, fuel lines, etc.) are hidden behind or under the surface to avoid damage or personal injury.
Use an existing grommet, add a new grommet, or apply silicone to protect the power wire from sharp edges.
