Tekonsha is a leading manufacturer of electronic trailer brake controllers, pioneering the category in the 1970s. The lineup spans proportional units such as the Prodigy P3 and Prodigy iD, time-delayed controllers, the wireless Prodigy RF, plus vehicle-specific wiring harnesses, adapters and trailer brake components engineered for smooth, predictable stopping at any speed.
Tekonsha Engineering Company began in 1964 building RV steps and mirrors. Within a few years it had found its real calling, and by the 1970s Tekonsha was pioneering the manufacture of electronic trailer brake controllers, the product category that still defines the brand. More than half a century later it remains the reference name in trailer braking and is part of the Horizon Global group alongside Reese, Draw-Tite, Fulton, Bulldog and Wesbar.
A brake controller is the component that tells a trailer's electric brakes how hard to work and when, and getting that right is the difference between a controlled stop and a shove from behind. Tekonsha builds both major types. Proportional controllers use an internal accelerometer to sense how quickly the tow vehicle is slowing and apply trailer braking to match, so light braking stays light and hard braking is immediate. Time-delayed controllers ramp to a preset output over a fixed interval, a simpler and more economical approach that suits occasional towing.
The current brake controller range covers most of that ground. The Prodigy iD pairs with a phone through Tekonsha's EDGE technology for setup and monitoring, the P3 offers storable settings for multiple trailers and a trilingual colour LED display, the Prodigy P2 adds a dimmable display and boost mode for heavier loads, and the Voyager keeps operation simple and dependable. The Prodigy RF mounts to the trailer itself and controls wirelessly, which suits rental fleets and drivers who swap tow vehicles.
Installation is supported by vehicle-specific brake control harnesses that plug into a factory connector rather than requiring cut-and-splice wiring, along with mounting brackets and adapters. Matched controller bundles pair a unit with the correct harness. Products are tested to meet and often exceed published industry standards.

The 2017-2020 Lincoln Continental, 2016-2018 Lincoln MKX Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118682 (Part #TK118682) Drilling is required for installation. Basic hand tools are typically all you need.
The T-Connector is a trailer wiring interface module designed for the Lincoln MKX. It allows you to connect a trailer's electrical harness to your vehicle's taillight system by intercepting the vehicle's taillight signals and routing them to a 4-Flat connector mounted under the vehicle. The module uses a 15 amp fuse for circuit protection.
Yes, the T-Connector (part number 118682-037) is designed for the Lincoln MKX. The installation instructions are specific to this vehicle model.
You will need: Torx 25 driver, 10 mm socket or wrench, 5.5 mm or 7/32" socket or wrench, trim panel remover, drill with 3/32" drill bit, Phillips head screwdriver, and a test probe.
The T-Connector kit includes: double-sided tape for mounting the black box module, yellow butt connectors (for wiring connections), a yellow fuse holder with a 15 amp fuse, a ring terminal, an eyelet and screw for grounding, and cable ties for securing the harness under the bumper.
No. The manual states "Mount 4-Flat in a suitable location under the vehicle. Bracket not included." You will need to source or fabricate a mounting bracket separately.
Yes. Step 8 requires you to disconnect the vehicle's negative (-) battery cable before connecting the fuse holder to the positive (+) battery cable. The negative cable is reconnected in step 11 after the fuse is installed.
Yes. Step 1 requires you to open the rear tailgate and remove the T-25 Torx screws holding the taillight housings in place, then carefully pry the housings rearward away from the vehicle without breaking the alignment tabs. The housings are reinstalled in step 12 after wiring is complete.
Yes, partially. Step 2 requires you to remove clips from the wheel well on both driver's and passenger's sides and remove all screws from the lower fascia area, then carefully pull back the fascia pieces to expose the area behind them underneath the vehicle. These are reinstalled in step 12.
Mount the black box underneath the vehicle behind the rear bumper fascia on the driver's side using the double-sided tape provided. The module must be mounted so that the epoxy side points toward the ground to prevent water buildup. Verify that the trailer's wire harness has adequate length to reach this mounting point.
Disconnect the vehicle wiring harness from both taillight sockets. On the driver's side, route the T-Connector end with yellow wires up between the bumper and vehicle body into the taillight pocket, then plug it in between the mating plugs on the driver's side taillight socket and vehicle wiring harness (step 5). Repeat the same process on the passenger's side with the T-Connector end with green wire (step 6).
Route the 4-Flat connector underneath the bumper from the driver's side to the passenger's side. Mount it in a suitable location under the vehicle (a bracket is not included, so you will need to source one separately).
In step 8, disconnect the vehicle's negative battery cable. Remove the fuse from the yellow fuse holder provided, cut the fuse holder wire, attach the ring terminal to the vehicle's positive (+) battery cable, and connect the other end of the fuse holder to the black 12 ga. wire using the yellow butt connector provided. In step 11, reconnect the negative battery cable and install the 15 amp fuse into the fuse holder.
Beginning from the front of the vehicle (step 9), route the black 12 ga. wire rearward along the frame rail, being careful to avoid hot pipes, heat shields, the fuel tank, or any points that may pinch or break the wire. In step 10, route the wire to the rear driver's side, locate the opening between the vehicle rear bumper and body, route the wire up through this hole, and attach it to the black wire from the T-Connector black box using the supplied yellow butt connector.
Yes. Step 7 requires you to drill a 3/32" hole near the black converter box to secure the white ground wire using the eyelet and screw provided. Before drilling, you must verify what is behind the surface to avoid damage to the vehicle or personal injury, and you must not drill into the vehicle floor, bed, or any exposed surfaces.
You need a 3/32" drill bit to drill the grounding hole in step 7.
Locate a suitable grounding point near the black converter box. Do not drill into the vehicle floor or bed. Clean dirt and rustproofing from the area before drilling the 3/32" hole.
The T-Connector uses a 15 amp fuse. This fuse is installed in the yellow fuse holder in step 11 after the battery is reconnected.
The wire connecting the battery to the T-Connector is 12 gauge (12 ga.) black wire.
The T-Connector has yellow wires on the driver's side end and green wires on the passenger's side end. These connect to the respective taillight sockets. The white wire is the ground wire, and the black wire connects to the battery positive terminal through the fuse holder.
The maximum stop/turn light capacity is 2 per side at 4.2 amps. Do not exceed this rating or the lower of your towing manufacturer's rating, as overloading the circuit can cause fires.
The maximum tail light capacity is 7.5 amps. Do not exceed this rating or the lower of your towing manufacturer's rating, as overloading the circuit can cause fires.
Route all wires carefully to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. The black 12 ga. wire should be routed along the frame rail from the front of the vehicle rearward. Cable ties are provided to secure the T-Connector harness under the bumper, and you should use them to avoid areas that would cut or pinch the wire.
After installation is complete, test and verify the installation with a test light or by connecting an actual trailer. This ensures that all taillight signals are properly transmitted through the T-Connector to the trailer connector.
After reinstalling the taillight housings in step 12, ensure that the vehicle wiring harness is positioned between the housing and the vehicle body. Verify that all covers, clips, and screws removed during installation are reinstalled. Secure the remainder of the T-Connector harness under the bumper with the provided cable ties, being careful to avoid areas that would cut or pinch the wire.
Yes, the T-Connector (part number 118682-037) is designed specifically for the Lincoln MKX.
Torx 25 driver, 10 mm socket or wrench, 5.5 mm or 7/32" socket or wrench, trim panel remover, 3/32" drill bit, Phillips head screwdriver, and test probe.
