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 18289-037 is a wiring adapter that connects your vehicle's factory electric brake control harness to an electronic trailer brake controller. It features a 6-pin connector that mates with the vehicle's brake control harness connector located under the dash, left of the steering column. The adapter houses male terminals on the wire side and includes connections for fused battery feed, stop lamp switch input, and trailer brake controller output.
Yes, the adapter can be used with vehicles not equipped with an OEM trailer tow package. However, these vehicles may require additional fuses and relays to complete the output and battery feed circuits. These fuses and relays are sold separately. You must consult your vehicle's owner's manual for the locations where these components should be installed.
Only a trim panel remover is required. This tool is needed to carefully remove the vehicle trim panel underneath the dash without damaging the courtesy lamp wires attached to it.
The vehicle's electric brake control harness connector is located underneath the dash and to the left of the steering column. It is taped to another harness near the emergency brake pedal. The connector is a 6-pin connector that mates with the 6-pin connector on the adapter.
Follow these steps in order: (1) Carefully remove the vehicle trim panel underneath the dash, being careful not to pull on courtesy lamp wires. (2) Locate the vehicle's electric brake control harness connector under the dash, left of the steering column, taped near the emergency brake pedal. (3) Plug the brake control adapter into the vehicle electric controller connector. (4) Complete installation per the electric brake control manufacturer's instructions, mount the unit as directed, and perform test procedures as instructed.
Yes. The brake control adapter must be plugged into the mating receptacle on the backside of the brake control before attaching the adapter to the vehicle connector. This is a required caution step that must be completed first.
The maximum capacity is 4 axles with 8 brakes, rated at 24 amps. Do not exceed this rating. Additionally, do not exceed the lower of either the towing manufacturer's rating or this 24-amp limit. Overloading the circuit can cause fires. Consult your vehicle's owner's manual and the brake controller instruction sheet for additional information.
Wear safety glasses during installation. Read and follow all vehicle warnings and installation instructions before beginning. When removing the trim panel, be careful not to pull on courtesy lamp wires attached to it. Do not overload the circuit—do not exceed the maximum of 4 axles, 8 brakes (24 amps), as overloading can cause fires.
Yes, but vehicles without OEM trailer tow package may require additional fuses and relays (sold separately) to complete output and battery feed circuits. Consult your vehicle's owner's manual for locations.
