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 Versa T-Connector is a taillight wiring integration device that allows you to connect a trailer to your vehicle's electrical system. It intercepts the vehicle's taillight wiring harness on both driver and passenger sides and provides a connection point for trailer lighting. The system includes a converter box, wiring harness with colour-coded leads (yellow, green, red, black, white), a fuse holder with a 10 amp fuse, and mounting hardware.
The kit includes: a black converter box, a T-Connector harness with colour-coded wires (yellow, green, red, black, white), a yellow fuse holder with a 10 amp fuse, a white eyelet and screw for grounding, yellow butt connectors, a ring terminal, double-sided tape for mounting the converter box, and cable ties for securing the harness.
The manual does not specify which vehicle makes, models, years, cab styles, or bed lengths are compatible with this T-Connector. Before purchasing, contact the manufacturer or your retailer with your vehicle's year, make, model, and body style to confirm fitment.
The T-Connector is designed to integrate with your vehicle's taillight wiring harness by inserting between the existing connectors on both the driver and passenger sides. The manual states that the taillight wiring harness will have a connection point on both sides matching the ends of the T-Connector. However, the manual does not specify which vehicles have compatible connectors. Verify compatibility with the manufacturer before installation.
You will need: a drill with a 3/32" drill bit, a Phillips head screwdriver, and a test probe. Safety glasses are also required during installation.
The manual lists a 3/32" drill bit as a required tool but does not state whether it is included in the kit. You should verify with your retailer or the product packaging whether the drill bit is provided or if you need to supply your own.
Yes. You must disconnect the vehicle's negative (−) battery cable before connecting the wiring to the battery. This is done in step 8. After all wiring connections are complete, you reconnect the negative battery cable and install the 10 amp fuse in step 9.
You must temporarily remove: the rear threshold plate, storage covers, floor covering, and partially remove the rear interior trim panels on both the driver and passenger sides. The manual notes that several trim panel fasteners will need to be removed. Set aside all removed items carefully to avoid damage, and reinstall them at the end of installation, being careful not to pinch or cut the wires.
On the driver's side, locate the vehicle's taillight wiring harness connector. Separate the connector carefully without breaking the locking tabs. Insert the T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place, ensuring the locking tabs are fully engaged. Repeat this process on the passenger side with the T-Connector end that has the green wire, routing it behind the panels and along the threshold. Ensure all connector surfaces are clean and free of dirt before connecting.
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. Secure the remainder of the T-Connector harness with the cable ties provided, being careful to avoid any areas that would pinch, cut, or melt the wire.
Locate a suitable grounding point near the connector, such as the vehicle's frame or cross member. Do not drill into the vehicle floor or bed. Clean dirt and rustproofing from the area, then drill a 3/32" hole. Secure the white wire using the eyelet and screw provided. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury.
Yes. You must drill one 3/32" hole for the grounding wire. This hole is drilled into the vehicle's frame or cross member (not the floor or bed) to secure the white grounding wire with an eyelet and screw. Before drilling, you must verify what is behind the surface to avoid damage to the vehicle or personal injury.
The T-Connector harness includes: yellow wire (driver-side taillight connector), green wire (passenger-side taillight connector), red wire (connects to black 12 ga. wire via yellow butt connector), black 12 ga. wire (connects to the fuse holder and vehicle battery positive terminal), and white wire (grounding wire, secured to vehicle frame or cross member with eyelet and screw).
From inside the vehicle, connect the black 12 ga. wire and the red wire from the T-Connector black box using the supplied yellow butt connector. You have two routing options: either route the black wire through a grommet and along the exterior frame, or follow the 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, be careful to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
The Versa T-Connector uses a 10 amp fuse. The fuse holder is provided with the kit and is installed in step 8. After cutting the fuse holder wire, attach the ring terminal to the vehicle's positive (+) battery cable, then connect the other end of the fuse holder to the black 12 ga. wire using a yellow butt connector. Install the 10 amp fuse into the fuse holder after reconnecting the negative battery cable.
With the vehicle's negative battery cable disconnected, 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. After all connections are complete, reconnect the negative battery cable and install the 10 amp fuse into the fuse holder.
Always wear safety glasses during installation. Before drilling, verify what is behind any surface to avoid damage to the vehicle or personal injury. Do not drill into exposed surfaces, the vehicle floor, or bed. When routing wires, avoid hot pipes, heat shields, the fuel tank, and any points that may pinch or break the wire. Read and follow all warnings and cautions printed on the vehicle's battery. Do not exceed the product's stated amperage ratings or the towing manufacturer's rating, as overloading circuits can cause fires.
All connections must be complete for the T-Connector to function properly. Test and verify the installation with a test light or trailer once installed. For the initial test, reset the vehicle's electrical system by temporarily removing the key from the ignition. Ensure all wiring is properly connected and secured before testing.
After installation, verify that: all connector locking tabs are fully engaged, all wiring connections are complete and secure, the converter box is mounted securely with double-sided tape, the harness is secured with cable ties to prevent damage or rattling, the grounding wire is properly secured with the eyelet and screw, all interior trim panels and threshold are reinstalled without pinching or cutting wires, and the 10 amp fuse is installed in the fuse holder. Test the installation with a test light or trailer and reset the vehicle's electrical system by temporarily removing the ignition key.
Store the 4-flat connector in the rear cargo area when not in use.
Do not exceed the lower of: the towing manufacturer's rating (including the rating in your vehicle's owner's manual) or the specific amperage rating stated on the product. The manual does not specify the product's amperage rating; check the product label or contact the manufacturer for this specification. Overloading circuits can cause fires.
The manual does not specify vehicle compatibility. Contact the manufacturer or retailer with your vehicle's year, make, model, and body style to confirm fitment before purchasing.
Yes, you must disconnect the vehicle's negative battery cable before connecting the wiring. Reconnect it after all connections are complete and the 10 amp fuse is installed.
