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 2018-2018 Volkswagen Tiguan Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118811 (Part #TK118811) Drilling is required for installation. Basic hand tools are typically all you need.
The T-One® Connector is a vehicle wiring interface that connects to your vehicle's taillight wiring harness on both driver and passenger sides. It allows you to connect a trailer or towing equipment by intercepting the vehicle's existing light signals. The connector includes a black box module, colored wires (yellow for driver side, green for passenger side), and a 4-flat connector for the trailer, which you store in the rear cargo area when not in use.
The manual shows installation on a Volkswagen Tiguan but does not provide a complete list of compatible vehicles. To confirm fitment, contact the manufacturer or your retailer with your vehicle's year, make, model, and body style. Compatibility depends on the vehicle's taillight wiring harness design and the ability to access and separate the connectors safely.
You will need: 10mm socket and ratchet or 10mm wrench, drill with 3/32" drill bit, wire crimpers, wire cutter, and Phillips head screwdriver. You will also need access to the vehicle's rear cargo area and the ability to locate and safely separate the taillight wiring harness connectors on both sides.
The kit includes: the T-One® Connector black box module, yellow and green connector ends, white wire with eyelet and screw for grounding, black 12 ga. power wire, yellow fuse holder with 15 amp fuse, yellow butt connector, double-sided tape for mounting the black box, cable ties for securing the harness, and a 4-flat connector for the trailer (to be stored in the rear cargo area when not in use).
Yes. You must disconnect the vehicle's negative (−) battery cable before making the final power connection. The battery remains disconnected until step 10, when you reconnect the negative cable after the fuse holder has been properly attached to the positive battery cable and connected to the black 12 ga. wire.
You must open the rear hatch and partially remove the plastic threshold cover, side panels, and cargo trays to access the vehicle's taillight wiring harness inside the rear cargo area. You will need to locate the taillight wiring connectors on both the driver and passenger sides. All connector surfaces must be clean and free of dirt before installation.
On the driver's side, insert the T-One® Connector end with the yellow wire between the vehicle's taillight wiring connectors and lock into place, being careful not to damage the locking tabs and ensuring full insertion. Repeat on the passenger's side with the green wire connector, routing it down the threshold. Both connectors must be fully inserted with locking tabs in place for proper function.
Mount the black box on the driver's side of the vehicle using the double-sided tape provided. The tape should be applied to a clean, dry surface near the taillight connector area.
You should first locate a suitable existing grounding point near the connector, such as an existing ground stud. If no suitable ground point exists, you may drill a 3/32" hole to secure the white ground wire using the eyelet and screw provided. Do not drill into the vehicle floor or bed. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Clean dirt and rustproofing from the area before securing the ground wire.
Do not drill into the vehicle floor or bed. Do not drill into any exposed surfaces. Always verify what is behind any surface before drilling to avoid damage to the vehicle or personal injury.
Locate the black 12 ga. power wire from the T-One® Connector black box on the driver's side. Route the black wire 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. If routing through a grommet and along the exterior of the vehicle, carefully avoid hot pipes, heat shields, the fuel tank, and any other points that may pinch or break the wire.
The power wire from the T-One® Connector black box to the battery is black 12 ga. (12 gauge). This wire is connected to the positive (+) battery cable through a yellow fuse holder containing a 15 amp fuse.
Install a 15 amp fuse into the yellow fuse holder provided. This fuse is installed in step 10, after the negative battery cable has been reconnected.
First, disconnect the vehicle's negative (−) battery cable. Remove the fuse from the yellow fuse holder if not already removed. Cut the fuse holder wire and attach the ring terminal to the vehicle's positive (+) battery cable. Connect the other end of the fuse holder to the black 12 ga. wire using the yellow butt connector provided. Then reconnect the negative battery cable and install the 15 amp fuse into the fuse holder.
The T-One® Connector uses three main wires: yellow wire (driver's side taillight connector), green wire (passenger's side taillight connector), and white wire (ground connection). The black 12 ga. power wire connects from the black box to the vehicle's positive battery through the fuse holder.
Always wear safety glasses during installation. Read and follow all warnings and instructions included with the product before beginning. Verify what is behind any surface before drilling. Do not drill into vehicle floor, bed, or exposed surfaces. Avoid hot pipes, heat shields, fuel tank, and pinch points when routing wires. Do not exceed the product's amperage rating or the towing manufacturer's rating. Read and follow all warnings and cautions printed on the vehicle's battery.
The manual specifies a 15 amp fuse but does not state an overall amperage rating for the connector. You must not exceed the lower of: the towing manufacturer's rating (including that in your vehicle owner's manual) or the specific amperage ratings stated on the product itself. Overloading circuits can cause fires.
After installation is complete, test and verify the installation with a test light or by connecting a trailer. The vehicle must be running to function test the T-One® Connector. All connections must be complete for the connector to function properly.
Store the 4-flat connector in the rear cargo area when not in use.
Secure the remainder of the T-One® 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. Then reinstall all plastic trim panels, threshold, storage covers, floor covering, and other items that were removed during installation, being careful not to pinch or cut the wires.
Drilling is optional. You should first locate an existing ground stud. If none is available, you may drill a 3/32" hole for the ground wire, but do not drill into the vehicle floor, bed, or exposed surfaces.
The T-One® Connector uses a 15 amp fuse in the yellow fuse holder provided.
Yes, disconnect the negative battery cable before making the final power connection in step 9. Reconnect it after the fuse holder is properly attached in step 10.
Always wear safety glasses during installation and follow all safety precautions.
Test with a test light or trailer while the vehicle is running. All connections must be complete for proper function.
