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.

Yes, the 2007-2011 Toyota Yaris Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118517 (Part #TK118517) is designed to fit the 2007-2011 Toyota Yaris.
The 2007-2011 Toyota Yaris Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118517 (Part #TK118517) fits the following vehicles: 2007-2011 Toyota Yaris. Always verify your specific year, make, and model before ordering.
The 2007-2011 Toyota Yaris Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118517 (Part #TK118517) Drilling is required for installation. Basic hand tools are typically all you need.
Yes, this T-Connector is designed for the Toyota Yaris Sedan. The installation instructions are specific to this vehicle model.
The T-Connector is a wiring adapter that integrates with your vehicle's taillight wiring harness to enable trailer light functionality. It includes a black converter box, connectors for both driver and passenger side taillights, and wiring to connect to your vehicle's battery.
You will need: trim panel remover, 10 mm socket and ratchet or 10 mm wrench, drill with 3/32" drill bit, 1/4" socket, wire crimpers, wire cutters, Phillips head screwdriver, and a test probe.
Yes. You must disconnect the vehicle's negative (−) battery cable before connecting the T-Connector to the positive (+) battery terminal in step 9. Reconnect the negative cable only after the fuse holder and 10 amp fuse are installed in step 10.
The T-Connector includes: two connector ends (one with yellow wire, one with green wire), a black converter box, a white ground wire with ring terminal, a red 12 gauge power wire, a black 12 gauge wire, a yellow fuse holder with 10 amp fuse, yellow butt connectors, an eyelet and screw for optional grounding, cable ties, and a 4-flat connector for storage in the spare tire compartment.
Mount the black converter box on the driver's side of the vehicle on a flat surface in an out-of-the-way location using the double-sided tape provided.
On the driver's side, locate the vehicle's taillight wiring harness in the trunk. Separate the connectors carefully without breaking the locking tabs. Insert the T-Connector end with the yellow wire between the vehicle's wiring connectors and lock into place, ensuring connectors are fully inserted with locking tabs engaged. Repeat this process on the passenger's side using the T-Connector end with the green wire, routing it under the felt trunk liner.
From the T-Connector black box, connect the red 12 gauge power wire with the supplied black 12 gauge wire using a yellow butt connector. Route the black 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, and the fuel tank.
Drilling is required only if you choose Option 2 for grounding. If you use the existing ground stud near the tow plug connector (Option 1), no drilling is needed. If you choose Option 2, drill a 3/32" hole in a suitable grounding point near the adapter, such as the vehicle frame or crossmember. Do not drill into the vehicle floor or bed.
Option 1: Locate the existing ground stud near the tow plug connector, loosen the nut, place the T-Connector white wire with ring terminal on the stud, and retighten the nut, ensuring all existing ground connections remain attached. Option 2: Locate a suitable grounding point near the adapter such as the vehicle frame or crossmember (do not drill into the vehicle floor or bed), clean dirt and rustproofing from the area, drill a 3/32" hole, and secure the white wire using the eyelet and screw provided.
Install a 10 amp fuse into the yellow fuse holder provided. This fuse protects the circuit and must be installed after the fuse holder is connected to the positive battery terminal and before the negative battery cable is reconnected.
Disconnect the vehicle's negative (−) battery cable. Locate the red 12 gauge power wire from the T-Connector black box and attach the supplied black 12 gauge wire. Connect the black wire and red wire from the T-Connector black box using the supplied yellow butt connector. Route the black wire to the battery through a grommet and exterior frame or along existing wiring. 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 gauge wire using the yellow butt connector. Install the 10 amp fuse and reconnect the negative battery cable.
Do not exceed the lower of the towing manufacturer's rating or: maximum 1 stop/turn light per side (2.1 amps) and maximum tail lights (5.6 amps). Overloading the circuit can cause fires.
After installation is complete, test and verify the installation with a test light or trailer. For the initial test, reset the vehicle's electrical system by temporarily removing the key from the ignition. All connections must be complete for the T-Connector to function properly.
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. Remove the plastic trim fasteners securing the protective cover to access the vehicle's wiring harness.
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. When reinstalling the felt trunk liner and threshold, be careful not to pinch or cut the wires.
Store the 4-flat connector in the spare tire compartment when not in use.
Wear safety glasses and use all safety precautions during installation. Read and follow all vehicle warnings and installation instructions before beginning. When routing wires, avoid hot pipes, heat shields, the fuel tank, and any points that may pinch or break the wire. Do not drill into the vehicle floor or bed. Follow all warnings and cautions printed on the vehicle's battery.
Yes. Before inserting the T-Connector, check that the mating surfaces of the vehicle harness connectors match the T-Connector ends. All connector surfaces should be clean and free of dirt.
Yes, this T-Connector is designed specifically for the Toyota Yaris Sedan.
You need: trim panel remover, 10 mm socket/ratchet or wrench, drill with 3/32" bit, 1/4" socket, wire crimpers, wire cutters, Phillips screwdriver, and test probe.
Yes, disconnect the negative battery cable before connecting to the positive terminal. Reconnect only after the fuse holder and 10 amp fuse are installed.
Install a 10 amp fuse in the yellow fuse holder provided.
Do not exceed 1 stop/turn light per side (2.1 amps) or maximum tail lights (5.6 amps). Overloading can cause fires.
Verify that all connections are complete. Check that the T-Connector ends are fully inserted into the vehicle's taillight connectors with locking tabs engaged. Ensure the white ground wire is properly connected to either the existing ground stud or the drilled grounding point. Verify that the 10 amp fuse is installed in the fuse holder and that the fuse holder is connected to both the positive battery terminal and the black 12 gauge wire. Test the installation with a test light or trailer. Reset the vehicle's electrical system by temporarily removing the ignition key.
Ensure that the mating surfaces of the vehicle harness connectors and T-Connector ends are clean and free of dirt. Verify that you are inserting the correct T-Connector end (yellow wire for driver's side, green wire for passenger's side) into the corresponding vehicle taillight connector. Be careful not to damage the locking tabs during insertion. Ensure the connectors are fully inserted until the locking tabs engage.
