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 T-Connector is a taillight wiring interface for Ford Freestyle and Ford Five Hundred vehicles. It allows you to connect trailer lighting to the vehicle's taillight circuit by inserting between the vehicle's existing taillight wiring connectors. The connector includes a yellow wire for the driver side, a green wire for the passenger side, and a white wire for grounding.
Yes, the T-Connector is designed for both Ford Freestyle and Ford Five Hundred vehicles. However, the installation procedure differs slightly between the two models: the Freestyle requires drilling a 3/32" hole for grounding, while the Five Hundred uses an existing ground stud. Both models require access to the taillight wiring harness and removal of interior trim panels.
A trim panel puller is required. For Ford Freestyle models, you will also need a drill capable of making a 3/32" hole. The eyelet and screw for grounding are provided with the T-Connector.
The manual does not specify whether the battery must be disconnected. Consult your vehicle's owner's manual for electrical work safety procedures before beginning installation.
For Ford Freestyle: Open the rear hatch and temporarily remove the rear threshold plate. Partially remove the rear interior trim panels on both the driver and passenger sides. Several trim panel fasteners will need to be removed. For Ford Five Hundred: Open the trunk and temporarily remove the rear threshold plate. Partially remove the felt trunk liner behind the taillights. Set aside all removed items carefully to avoid damage.
1. Locate the vehicle's taillight wiring harness on both driver and passenger sides. The harness will have connection points matching the T-Connector ends. 2. Separate the existing connector carefully without breaking the locking tabs. Ensure all connector surfaces are clean and free of dirt. 3. On the driver side, insert the T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place. Be careful not to damage the locking tabs and ensure connectors are fully inserted with locking tabs in place. 4. Route the T-Connector end with the green wire to the passenger side behind the panels and along the threshold, then repeat the insertion and locking process.
Yes. You must drill a 3/32" hole to secure the white grounding wire using the eyelet and screw provided. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into any exposed surfaces.
No. The Ford Five Hundred uses an existing ground stud for the white grounding wire. Locate the existing ground stud on the driver side, loosen the bolt, place the screw eyelet on the stud, and re-tighten the bolt.
For Ford Freestyle: Route the 4-flat connector from below the driver's side trim panel into the rear storage compartment and store it there when not in use. For Ford Five Hundred: Route the 4-flat connector from below the threshold plate into the trunk and store it there when not in use.
For Ford Freestyle: Reinstall the plastic trim panels, threshold, storage covers, floor covering and other items removed during installation, being careful not to pinch or cut the wires. For Ford Five Hundred: Reinstall the felt trunk liner, threshold, and other items removed during installation, being careful not to pinch or cut the wires.
Do not exceed 7.5 amps on the stop/turn light circuit or 7.5 amps on the tail light circuit. Overloading the circuit can cause fires. Consult your vehicle's owner's manual and the instruction sheet for additional information about circuit capacity.
All connections must be complete for the T-Connector to function properly. Test and verify the installation with a test light or by connecting a trailer once installed. Ensure all connector locking tabs are fully seated and all wires are properly routed and secured.
Yes, the T-Connector (18395-037) fits both models. Installation differs: Freestyle requires drilling a 3/32" hole for grounding; Five Hundred uses an existing ground stud.
You need a trim panel puller. For Ford Freestyle, you also need a drill for a 3/32" hole. The eyelet and screw for grounding are included.
Only for Ford Freestyle: drill a 3/32" hole for the grounding wire. Ford Five Hundred uses an existing ground stud and requires no drilling.
Maximum 7.5 amps on stop/turn light circuit and 7.5 amps on tail light circuit. Exceeding these limits can cause fires.
Ford Freestyle: rear threshold plate and rear interior trim panels on both sides. Ford Five Hundred: rear threshold plate and felt trunk liner behind taillights.
Test with a test light or by connecting a trailer once installed. Ensure all connector locking tabs are fully seated and all wires are properly routed.
