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 manual does not specify vehicle compatibility or exclusions. It is designed to integrate with vehicles that have accessible tail light assemblies with removable connectors. Consult the manufacturer or a fitment database to confirm compatibility with your specific vehicle make, model, and year.
You will need a drill with a 3/32" drill bit to create the grounding hole. A screwdriver is required to remove and reinstall tail light assembly screws. A test light or trailer is needed to test the installation after completion. Cable ties or a screw are provided to secure the black box and wires to the vehicle frame.
The package includes an eyelet and screw for grounding the white wire, and cable ties or a screw to secure the black box and wires to the vehicle frame.
Yes. The first step requires removing both tail light assemblies to access the tail light connectors. The lens cover, seal, and housing will separate when the screws are removed.
Beginning on the left (driver's) side, route the T-connector's harness containing the 3 bonded wires out from under the vehicle through the tail light opening. Then route the connector with the green wire across the vehicle along the vehicle frame and out from under the vehicle through the right (passenger) side tail light opening.
Disconnect the vehicle's wiring harness connector from the tail light assembly. Plug the T-connector between the separated halves, ensuring the connectors are fully inserted together. Repeat this process for both the left (driver's) side and right (passenger) side using the appropriate connector (the one with the green wire for the right side).
Locate a suitable grounding point near the connector on the vehicle frame. Drill a 3/32" hole at this location. Do not drill into the vehicle floor or other exposed surfaces.
Drill a 3/32" hole for the grounding point.
No. Do not drill into the vehicle floor or other exposed surfaces. Locate a suitable grounding point on the vehicle frame instead.
The T-connector includes a white wire (used for grounding), a green wire (routed to the right/passenger side), and 3 bonded wires in the main harness routed from the left/driver's side. The manual does not specify the function of individual wires beyond the white ground wire and green wire routing.
Secure the white wire using the eyelet and screw provided. First, locate a suitable grounding point near the connector on the vehicle frame and drill a 3/32" hole. Insert the eyelet through the hole and tighten the screw to secure the white wire.
Test the installation with a test light or trailer. This should be done before reinstalling the tail light assemblies.
After testing with a test light or trailer, reinstall the tail light assemblies removed in step 1, ensuring the seals are securely in place. Secure the black box and wires to the vehicle frame with the screw or cable ties provided.
Secure the black box and wires to the vehicle frame using either a screw or the cable ties provided with the kit.
The seals prevent water and moisture from entering the tail light assemblies, which could cause electrical damage or corrosion. The manual specifies that seals must be securely in place when reinstalling the tail light assemblies.
This T-connector is designed for vehicles with accessible tail light assemblies and removable connectors. The manual does not list specific vehicle compatibility. Check with the manufacturer or a fitment database for your vehicle make, model, and year.
