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 2005-2010 Honda Odyssey Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118438 (Part #TK118438) is designed to fit the 2005-2010 Honda Odyssey.
The 2005-2010 Honda Odyssey Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118438 (Part #TK118438) fits the following vehicles: 2005-2010 Honda Odyssey. Always verify your specific year, make, and model before ordering.
The 2005-2010 Honda Odyssey Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118438 (Part #TK118438) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The T-Connector is a vehicle electrical junction box that provides trailer lighting connections. It plugs into your vehicle's electric junction box and allows you to connect a trailer's lighting system to your vehicle's electrical system.
The manual does not specify vehicle year, make, or model compatibility. Contact the manufacturer or your retailer with your vehicle's details to confirm fitment before purchase.
You will need a trim panel remover and pliers. The trim panel remover is used to safely remove the passenger side rear cargo area trim panel without damage.
The T-Connector includes a black junction box, a grey connector, a white ground wire, a 4-flat wire connector, a 7.5 amp fuse, a fuse label, and double-sided tape for mounting the black box.
The manual does not specify whether battery disconnection is required. Consult your vehicle's owner's manual or contact the manufacturer before beginning installation.
The electric junction box is located in the passenger side rear cargo area. You will need to remove the passenger side rear cargo area trim panel to access it. The manual refers to it as the vehicle's black electric junction box.
Yes. The first step requires you to open the rear tailgate, remove the cargo liner and threshold, and set them aside carefully to avoid damage. These items must be repositioned and the threshold reattached at the end of installation.
Plug the grey connector into the mating connection in the top right corner of the electric junction box. Mount the white ground wire to the existing ground stud next to the electric junction box. Mount the black box using the double-sided tape provided on a clean, flat surface inside the passenger side trim panel.
Route the 4-flat wire across to the driver's side under the threshold and cable tie it to the factory wiring harness. Then route it under the driver side trim panel and store it in the jack compartment for future use.
Install the 7.5 amp fuse provided with the T-Connector into fuse position #5 in the vehicle's fuse box. Attach the fuse label to the fuse cover in position #5. Do not use a larger fuse.
The fuse compartment is located on the passenger side kick panel, near the glove box.
The T-Connector is protected by a 7.5 amp fuse. Do not exceed the lower of your vehicle's towing manufacturer rating or the following limits: maximum stop/turn light 1 per side (2.1 amps), and maximum tail lights (4.2 amps). Exceeding these limits can cause circuit overload and fires.
The maximum load for stop/turn lights is 1 per side at 2.1 amps. Do not exceed this limit, as overloading the circuit can cause fires.
The maximum load for tail lights is 4.2 amps. Do not exceed this limit, as overloading the circuit can cause fires.
Using a fuse larger than 7.5 amps could result in damage to the vehicle and/or trailer. The 7.5 amp fuse is designed to protect the electrical circuit from overload and fire. Always use the 7.5 amp fuse provided.
Test and verify the installation with a test light or by connecting a trailer once installed. All connections must be complete for the T-Connector to function properly. If the test light does not illuminate or the trailer lights do not work, check that all connections are secure.
After installation, verify that all connections are complete and secure. Test the installation with a test light or by connecting a trailer to ensure the T-Connector is functioning properly. Check that the grey connector is fully seated in the electric junction box, the white ground wire is secure on the ground stud, and the 7.5 amp fuse is properly installed in position #5.
The manual does not list specific vehicle compatibility. Verify with the manufacturer or retailer using your vehicle's year, make, and model before purchase.
The manual does not specify whether professional installation is required. The installation involves removing trim panels, connecting electrical components, and installing a fuse. If you are not comfortable working with vehicle electrical systems, consult a professional installer.
Use only the 7.5 amp fuse provided. Do not use a larger fuse, as this could damage the vehicle and/or trailer.
Maximum stop/turn light is 1 per side (2.1 amps); maximum tail lights are 4.2 amps. Do not exceed the lower of your vehicle's towing manufacturer rating or these limits.
Test with a test light or by connecting a trailer. All connections must be complete and secure for proper function.
Verify that all connections are complete and secure: (1) the grey connector is fully plugged into the electric junction box, (2) the white ground wire is firmly mounted to the ground stud, (3) the 7.5 amp fuse is installed in fuse position #5 and the fuse is not blown, and (4) the 4-flat wire is properly routed and connected. Test with a test light to confirm power is reaching the connector.
A blown fuse indicates circuit overload or a short circuit. Verify that the total amperage of connected trailer lights does not exceed the limits: maximum 2.1 amps for stop/turn lights per side and 4.2 amps for tail lights. Check all electrical connections for damage, corrosion, or loose wires. Do not replace the fuse with a larger one. If the problem persists after verifying the load and connections, there may be a short circuit in the wiring or trailer lights.
