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 2009-2012 Volkswagen Routan Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118490 (Part #TK118490) is designed to fit the 2009-2012 Volkswagen Routan.
The 2009-2012 Volkswagen Routan Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118490 (Part #TK118490) fits the following vehicles: 2009-2012 Volkswagen Routan. Always verify your specific year, make, and model before ordering.
The 2009-2012 Volkswagen Routan Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118490 (Part #TK118490) Drilling is required for installation. Basic hand tools are typically all you need.
Yes, the T-Connector (118490-037) is designed for the Volkswagen Routan. The installation instructions are specific to this vehicle model.
The T-Connector is a trailer wiring interface that connects between your vehicle's taillight wiring harness and a trailer connector. It allows you to plug in a trailer's 4-flat connector when needed, and stores in the jack storage compartment when not in use.
You will need: trim panel remover, Torx 30 driver, drill with 3/32" bit, 1/4" socket, utility knife, wire cutters, Phillips head screwdriver, and test-probe. Safety glasses are also required.
The manual does not specify whether the battery must be disconnected. Consult your vehicle's owner's manual or a qualified technician for guidance on electrical work safety.
Open the tailgate and remove the vehicle's taillight assemblies by removing the two T30 Torx head bolts on each side. Carefully pry the taillight housings rearward away from the vehicle, being careful not to break the alignment tabs.
The T-Connector end with the yellow wire goes on the driver's side. Plug it in between the mating plugs on the driver's side taillight socket and vehicle wiring harness. Ensure all connector surfaces are clean and free of dirt, and that connectors are fully inserted with locking tabs in place.
The T-Connector end with the green wire goes on the passenger's side. Repeat the same connection process as the driver's side: plug it in between the mating plugs on the passenger's side taillight socket and vehicle wiring harness, ensuring connectors are fully inserted with locking tabs in place.
Route the harness containing the green wire down the opening behind the taillight on the driver's side. Then route the harness across and underneath the vehicle behind the bumper fascia, and up through the opening behind the passenger's side taillight. Route the wire carefully to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
Yes, you must drill a 3/32" hole to secure the white ground wire. Locate a suitable grounding point near the connector such as the vehicle's frame or crossmember. Do not drill into the vehicle floor, bed, or any exposed surfaces. Clean dirt and rustproofing from the area before drilling. Verify what is behind any surface prior to drilling to avoid damage to the vehicle and personal injury.
Secure the white wire using the eyelet and screw provided. Drill a 3/32" hole at a suitable grounding point near the connector, such as the vehicle's frame or crossmember. Clean dirt and rustproofing from the area first. Insert the eyelet and screw through the white wire into the drilled hole.
On the driver's side, open the jack storage door and remove the jack, tools, and carpeting to gain access to the vehicle wiring and the grommet hole.
The grommet is a rubber seal on the vehicle's taillight wire harness. To install the T-Connector, you must unseat the grommet and remove it from the vehicle harness by untaping the tabs and slitting the grommet as shown in the manual. After routing the 4-flat connector through the grommet hole, place the grommet onto the T-Connector wiring between the T-Connector and the mating vehicle end, retape the tabs, and reseat the grommet into the hole.
Route the vehicle connector and the 4-flat end through the grommet hole into the jack storage area. When not in use, store the 4-flat connector in the jack storage compartment. When in use, route the 4-flat harness through the rear tailgate/door seal. Be careful not to pinch the harness in the door latch.
Secure all loose wires with cable ties. Reinstall the taillight assemblies and other items removed during installation, being careful not to pinch or cut the wires.
Do not exceed the lower of your towing manufacturer's rating or: maximum 7.5 amps for stop/turn lights, and maximum 7.5 amps for tail lights. Overloading the circuit can cause fires. Consult your vehicle's owner's manual and instruction sheet for additional information.
All connections must be complete for the T-Connector to function properly. Test and verify the installation with a test light or by connecting an actual trailer once installed. Use the test-probe tool to verify proper electrical connections.
Before reinstalling the taillight assemblies, ensure all loose wires are secured with cable ties and that no wires will be pinched or cut when the assemblies are reattached. Verify that the grommet is properly reseated and that all connections are complete and secure.
The T-Connector has three colored wires: yellow (driver's side connection), green (passenger's side connection and harness routing), and white (ground wire). The yellow and green wires connect to the respective taillight sockets, while the white wire must be grounded to the vehicle's frame or crossmember.
Yes, the T-Connector (118490-037) is designed specifically for the Volkswagen Routan.
You need: trim panel remover, Torx 30 driver, 3/32" drill bit, 1/4" socket, utility knife, wire cutters, Phillips head screwdriver, test-probe, and safety glasses.
Maximum 7.5 amps for stop/turn lights and 7.5 amps for tail lights. Do not exceed the lower of your towing manufacturer's rating or these limits, as overloading can cause fires.
Yes, you must remove both taillight assemblies by removing the two T30 Torx bolts on each side and carefully prying the housings rearward.
Test and verify the installation with a test light or by connecting an actual trailer. All connections must be complete for proper function.
