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, this T-Connector is designed for the Cadillac XT5. The installation accesses the grey 4-pin connector located behind the rear bumper access cover.
You need a 7 mm socket or wrench, a trim panel puller, and a test-probe. A bracket or electrical box (not included) is also required to mount the 4-flat end in an accessible location.
The grey 4-pin connector is located behind the access cover in the rear bumper area of the vehicle. You access it by removing the two bolts holding the access cover with a 7 mm socket or wrench.
First, remove the factory tow harness protective cap and clean the mating surface if necessary. Insert the 4-pin tow plug adapter into the grey 4-pin connector and lock it into place. Ensure the connectors are fully inserted with the locking tabs in place.
Secure the remainder of the T-Connector harness with the cable ties provided. Be careful to avoid any areas that would pinch, cut or melt the wire, and prevent damage or rattling.
Mount the 4-flat end in an accessible location using a bracket or electrical box (not included with the product). The manual does not specify exact mounting location details.
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.
Do not exceed the lower of two ratings: the towing manufacturing rating stated in your vehicle owner's manual, or the specific amperage ratings stated on the product itself. Overloading circuits can cause fires.
All connections must be complete for the T-One T-Connector to function properly. Incomplete connections may result in improper operation or electrical hazards.
Yes. Before inserting the 4-pin tow plug adapter, remove the factory tow harness protective cap and check that the mating surface is clean and free of dirt. Clean it if necessary.
Carefully remove the access cover and set it aside during installation. After completing all other installation steps, replace the cover.
Always wear safety glasses and use all safety precautions during installation. Read and follow all warnings and instructions included with the product and in your vehicle's owner's manual before beginning.
