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. You must locate the vehicle's battery, disconnect and isolate the negative battery cable before beginning installation. Always wear safety glasses during installation.
The hardware kit includes: double-sided tape, test light, 6-inch cable ties, and a panel puller. Safety glasses are required but must be provided by the installer. A bracket or electrical box for mounting the 4-Flat connector end is not included.
The manual does not describe any drilling, cutting, trimming, or welding as part of the installation process. The T-Connector is mounted using double-sided tape, and the 4-Flat harness is secured with cable ties.
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. All connections must be complete for the T-One® T-Connector to function properly.
DO NOT touch the negative battery terminal to the positive battery terminal. Serious injury and damage to the vehicle's electrical system can occur. Additionally, overloading circuits can cause fires—do not exceed stated product ratings or the towing manufacturing rating in your vehicle owner's manual.
Perform a pre-trip inspection of the 4-Way flat harness to ensure no damage to terminals and connection points. Clean the 4-Way flat connector after each use. Clean the connection and add dielectric grease (sold separately) to the terminal pins. Ensure the harness does not get pinched in door latches, trailer connection points, or contact the road surface.
The T-One® T-Connector (part 118784) is a trailer wiring harness that connects your vehicle's factory trailer connector to a 4-Flat trailer connector. It allows you to tow a trailer by providing electrical connections for trailer lights and functions. The system uses a 12-pin T-Connector that plugs into the vehicle's factory harness and routes a 4-Flat connector to the rear of the vehicle for trailer connection.
Yes, the T-One® T-Connector (part 118784) is compatible with Hyundai Santa Fe. However, visit the Horizon Global website for the most up-to-date information regarding specific application years and trim levels, as compatibility may vary by model year.
If your vehicle is equipped with the Start/Stop option, you must connect the module only to the main vehicle battery, not to the support battery. Failure to connect to the main vehicle battery may result in damage to the module. Consult your vehicle owner's manual to determine if your vehicle has this feature.
The factory trailer harness connector is located under the vehicle, behind the rear bumper, on the driver's side of the vehicle. A plastic cover may need to be removed to access the T-One® T-Connector harness.
Yes. Before inserting the T-One® T-Connector, check that the mating surfaces of the connectors are free of dirt and clean them if necessary. This ensures a proper electrical connection.
Mount the T-Connector black box using the double-sided tape provided. First, clean the flat mount surface area using a 50-50 mixture of rubbing alcohol and water. Mount the box behind the rear bumper fascia on the driver's side, ensuring the trailer wire harness has adequate length to reach this point. The epoxy side of the module must point toward the ground to prevent water buildup. Always mount the unit in a protected area where it cannot be damaged by road debris or objects driven over it.
Route the 4-Flat harness rearward along the back of the bumper fascia to the center of the vehicle. Secure the remainder of the harness with the 6-inch cable ties provided to prevent damage or rattling. Be careful to avoid any areas that would pinch, cut, or melt the wires. If routing the wire through a grommet and along the exterior of the vehicle, avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
Mount the 4-Flat end in an accessible location with a bracket or electrical box. The bracket or electrical box is not included with the T-One® T-Connector kit and must be purchased separately. Choose a location that is easily accessible for trailer connection and disconnection.
Yes. After routing the harness and mounting the T-Connector, reinstall the plastic cover that was removed to access the factory connector. Be careful not to break any plastic securing pins when reinstalling the cover.
Insert the 12-pin T-One® T-Connector harness and lock it into place. Ensure that the connectors are fully inserted with locking tabs in place. The locking tabs must be engaged to confirm a secure connection.
Remove the protective cap from the factory connector and store it in the glove compartment along with the installation instructions. This keeps the cap safe for future reference and prevents it from being lost.
The installation difficulty is rated as Novice. Installation times are listed on Horizon Global websites or found in downloadable application guides. Difficulty levels are based on time and effort involved and may vary depending on installer expertise and vehicle condition, along with proper tools and equipment.
After installation, test and verify the installation with a test light or trailer. For the initial test, reset the vehicle electrical system by temporarily removing the key from the ignition. All connections must be complete for the T-One® T-Connector to function properly. Ensure all existing ground connections are still attached and torque existing ground screws to manufacturer torque specifications.
Torque existing ground screws to manufacturer torque specifications. The manual does not provide a specific torque value; refer to your vehicle manufacturer's specifications or contact Horizon Global technical support at 800-632-3290 for the correct torque value for your specific vehicle.
The test light is used to verify proper electrical connections after installation. Use it to test the T-One® T-Connector and confirm that all electrical connections are functioning correctly before towing a trailer.
Dielectric grease is a non-conductive lubricant that protects electrical connections from moisture and corrosion. After cleaning the 4-Way flat connector, apply dielectric grease to the terminal pins to maintain a clean connection and prevent oxidation. Dielectric grease is sold separately and is not included with the T-One® T-Connector kit.
Perform a pre-trip inspection of the 4-Way flat harness before each towing trip to ensure no damage to terminals and connection points. This ensures proper lighting connection and operation. Additionally, clean the 4-Way flat connector after each use.
First, ensure the T-One Connector ends are fully inserted and locked in place. If they are not fully seated, remove the connector and reinsert it, making sure the locking tabs engage. Then remove the module's power fuse for 10 seconds and repeat the test. If the connector still does not function, check the chassis grounds to ensure ring terminals are in full contact with the vehicle chassis.
Several issues could cause no power: (1) Installation may have activated circuit protection—start the vehicle and turn off all functions (tail lights, brake, turns), then remove the module power fuse for 10 seconds and repeat the test. (2) Ensure the fuse is fully inserted into the fuse holder and has no breaks. (3) Verify the fuse holder is connected properly to the positive post of the battery. (4) Ensure the module is connected to B+ (positive battery). Using a tester or voltmeter, check for voltage on either side of the yellow butt connector near the module. Remove the module power fuse for 10 seconds and repeat the test.
Remove the 12-pin T-One® T-Connector harness from the factory connector and inspect both the connector and the mating surfaces for dirt or debris. Clean the mating surfaces if necessary. Reinsert the T-Connector harness and ensure it is fully inserted with the locking tabs in place. You should hear or feel the connector lock into position.
Ensure the 4-Flat harness is properly secured with the 6-inch cable ties provided. Route the harness rearward along the back of the bumper fascia and secure it to prevent damage or rattling. Make sure the cable ties are tight enough to hold the harness in place but not so tight that they pinch or damage the wires. Also ensure the 4-Flat connector end is mounted securely in a bracket or electrical box.
