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 1996-2002 Toyota 4Runner Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118341 (Part #TK118341) Drilling is required for installation. Basic hand tools are typically all you need.
This unit is rated for 4 amps per circuit.
This T-connector adapter is designed for vehicles with tail light wiring harnesses that have connection points on both the left (driver) and right (passenger) sides with connectors matching the T-connector adapter ends. If your vehicle has this dual-connector tail light harness configuration, the adapter will fit. Consult your vehicle's wiring diagram or contact the manufacturer if you are unsure whether your specific vehicle model is compatible.
You will need a drill with a 3/32" drill bit, a screwdriver (to remove and reinstall screws), and a test light or trailer to verify the installation. The eyelet and screw for grounding the white wire are provided with the adapter.
Open the rear door and remove the five screws attaching the threshold panel. Then remove the shade latch screws on each side of the vehicle and carefully pull the plastic trim panels away from the sides to expose the vehicle wiring.
Separate the harness connectors on the left (driver) side of the vehicle, being careful not to break the locking tabs. Insert the T-connector harness with the yellow wire between the harness connectors and lock into place. Ensure that the connectors are fully inserted with locking tabs in place.
Repeat the process used for the left side: separate the harness connectors on the right (passenger) side, being careful not to break the locking tabs. Insert the T-connector harness with the green wire between the harness connectors and lock into place. Ensure that the connectors are fully inserted with locking tabs in place.
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 and secure the white wire using the eyelet and screw provided.
Use a 3/32" drill bit to create the grounding hole for the white wire.
Route the yellow wire under the threshold panel. Then secure the threshold and side panels with the screws removed in steps 1 and 2.
Test the installation with a test light or trailer. This will verify that the connections are correct and the adapter is functioning properly.
The T-connector adapter uses three wires: yellow (connects to the left/driver side tail light harness), green (connects to the right/passenger side tail light harness), and white (ground wire that connects to the vehicle frame or cross member via a 3/32" hole with eyelet and screw).
The manual warns to be careful not to break the locking tabs when separating the harness connectors. If a locking tab is broken, the connector may not stay securely in place. Contact the manufacturer or a qualified installer for guidance on repair or replacement options.
Clean dirt and rustproofing from the grounding area before drilling the 3/32" hole for the white wire.
This T-connector adapter fits vehicles with dual tail light wiring harnesses on both left (driver) and right (passenger) sides with matching connectors. Check your vehicle's wiring configuration or contact the manufacturer to confirm compatibility.
You need a drill with a 3/32" bit, a screwdriver, and a test light or trailer. The eyelet and screw for grounding are included.
Yes, you must drill a 3/32" hole in the vehicle frame or cross member to secure the white ground wire using the provided eyelet and screw. Do not drill into the vehicle floor or bed.
This unit is rated for 4 amps per circuit.
Yellow wire connects to the left (driver) side; green wire connects to the right (passenger) side; white wire is the ground connection to the vehicle frame or cross member.
Test the installation with a test light or trailer to verify that the connections are correct and functioning properly.
