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 T-Connector is a trailer wiring interface that connects to your vehicle's taillight wiring harness to provide trailer lighting control. It includes a black converter box, wiring harness with yellow, brown, green and red wires, a 4-flat connector for storage when not in use, and a fused power connection to the vehicle battery.
Yes, this T-Connector (part number 118548-037) is designed for the Ford Focus Sedan. The installation instructions are specific to this vehicle model.
You will need: trim panel remover, 10mm socket and ratchet or 10mm wrench, drill with 3/32" drill bit, wire crimpers, wire cutters, test probe, and Phillips head screwdriver.
The kit includes the T-Connector harness with yellow, brown, green and red wires, a black converter box with double-sided tape, a white ground wire with eyelet and screw, a 12 gauge black power wire, a yellow fuse holder with 10 amp fuse, a yellow butt connector, and cable ties for securing the harness.
Yes. You must disconnect the vehicle's negative (-) battery cable before connecting the power wire to the positive battery terminal. The negative cable is reconnected after the fuse holder is installed in step 10.
Open the trunk and remove the threshold panel. Partially remove the corner felt trunk liner on both sides to expose the vehicle's taillight wiring harness.
On the driver's side, locate the vehicle's taillight wiring harness and separate the connectors carefully without breaking the locking tabs. Verify that the mating surfaces are clean and match the T-Connector ends. Attach the T-Connector end containing yellow and brown wires, ensuring connectors are fully inserted with locking tabs in place. Route the T-Connector with green and red wires below the threshold cover to the passenger's side taillight housing and repeat the connection process.
Mount the black converter box on the driver's side in a flat surface location that is out of the way, using the double-sided tape provided.
Yes. You must drill a 3/32" hole on the driver's side near the connectors to secure the white ground wire with an eyelet using the screw provided. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into any exposed surfaces.
The T-Connector uses a 10 amp fuse. The fuse holder is provided in the kit and must be installed in the power circuit between the vehicle's positive battery terminal and the black 12 gauge power wire.
Locate the red 12 gauge power wire from the T-Connector box on the driver's side and attach the black 12 gauge wire provided. Route the black wire either through a grommet along the exterior frame or along existing wiring through the thresholds into the engine compartment to the battery, avoiding areas that may pinch or break the wire. Disconnect the negative battery cable, then attach the ring terminal from the fuse holder to the vehicle's positive (+) battery cable. Connect the other end of the fuse holder to the black 12 gauge wire using the yellow butt connector provided. Reconnect the negative battery cable and install the 10 amp fuse.
The T-Connector harness includes yellow and brown wires that connect to the driver's side taillight connector, and green and red wires that connect to the passenger's side taillight connector. A white ground wire connects to a grounding point on the driver's side. A black 12 gauge power wire connects to the vehicle's positive battery terminal through a fused connection.
Route the black 12 gauge power wire either through a grommet and along the exterior frame, or follow existing wiring along the thresholds into the engine compartment up to the battery. Avoid areas that may pinch or break the wire, hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
Route the 4-flat connector through the driver's side trim panel into the side storage compartment and store it there when not in use.
Secure the remainder of the T-Connector harness with the cable ties provided to prevent damage or rattling. Be careful to avoid any areas that would pinch, cut or melt the wire.
All connections must be complete for the T-Connector to function properly. Test and verify installation with a test light or trailer once installed. For the initial test, reset the vehicle electrical system by temporarily removing the key from the ignition.
Do not exceed the lower of the towing manufacturer rating (including in your vehicle owner's manual) or the specific amperage ratings stated on the product. Overloading circuits can cause fires.
Always wear safety glasses and use all safety precautions during installation. Before drilling, verify what is behind any surface to avoid damage to the vehicle or personal injury. Do not drill into exposed surfaces. Be careful not to pinch the harness in the trunk latch. Avoid routing wires through areas with hot pipes, heat shields, or the fuel tank. Read and follow all warnings and cautions printed on the vehicle battery.
After securing the harness with cable ties, reinstall the plastic trim panels, threshold, storage covers, floor covering and other items removed during installation, being careful not to pinch or cut the wires.
Yes, this T-Connector (part 118548-037) is designed specifically for the Ford Focus Sedan.
You need: trim panel remover, 10mm socket/ratchet or wrench, drill with 3/32" bit, wire crimpers, wire cutters, test probe, and Phillips screwdriver.
Yes, disconnect the negative battery cable before connecting the power wire to the positive terminal. Reconnect it after installing the fuse holder.
