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 2002-2007 Saturn Vue Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118418 (Part #TK118418) fits 2002-2007 Saturn Vue models. The 2007 model year is the last year covered by this part number. For newer models, check for an updated version.
The 2002-2007 Saturn Vue Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118418 (Part #TK118418) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The T-Connector is a trailer wiring adapter for Saturn Vue vehicles. It intercepts the vehicle's taillight signals and provides a 4-flat connector for trailer lights. It uses a black box mounted behind the driver's side taillight and T-shaped connectors that plug between the vehicle's taillight wiring and the taillight assemblies on both sides.
Yes, the T-Connector (part 118418-037, Rev. A) is designed for Saturn Vue vehicles. The installation instructions are specific to this vehicle model.
You will need: a trim panel remover, 10mm socket and ratchet (or 10mm wrench), Torx-15 screwdriver, and #2 Phillips screwdriver. The manual also recommends using a fish wire between the taillight pocket and wheel well to ease routing the harness.
The T-Connector includes: double-sided tape for mounting the black box, an eyelet and screw for securing the white grounding wire, and cable ties for securing loose wires.
Tire removal is optional but recommended for ease of installation. The manual states: "For ease of installation remove tires and completely remove wheel well and mud guard." You can install without removing tires by partially removing the wheel well and mud guard instead.
The manual does not specify whether the battery must be disconnected before installation. For safety, consult your vehicle's owner's manual or a qualified technician before beginning work.
Open the rear liftgate. On both the driver and passenger sides, remove two Torx-15 screws and carefully pull the taillight away from the vehicle without damaging the alignment pins. Locate the vehicle's taillight wiring harness connector on each side. These connectors match the ends of the T-Connector and must be separated carefully without breaking the locking tabs. Ensure all connector surfaces are clean and free of dirt before proceeding.
Route the 4-flat harness to the center of the vehicle. From the driver's side taillight pocket, route the T-Connector end with the green wire and 4-flat through the wheel well opening. From underneath, locate this end and route both rearward to the backside of the bumper fascia. Then route the 4-flat to the center of the vehicle and the green-wire end along the backside of the bumper fascia to the passenger side wheel well opening and taillight pocket. Temporarily disconnecting bumper fascia brackets eases this step. Use a fish wire between the taillight pocket and wheel well if needed.
Route the wire carefully to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. Do not allow wires to contact areas that could pinch, cut, or melt them. Secure all loose wires with the cable ties provided to prevent damage, rattling, and further hazards.
Yes. You must drill a 3/32" hole to secure the white grounding wire. Locate a suitable grounding point near the adapter such as the vehicle frame or crossmember. Do not drill into the vehicle floor or bed. Before drilling, verify what is behind the surface to avoid damage to the vehicle and personal injury. Do not drill into any exposed surfaces. Clean dirt and rustproofing from the area, then drill the hole and secure the white wire using the eyelet and screw provided.
The grounding hole must be 3/32" in diameter. This hole is drilled in the vehicle frame or crossmember to secure the white grounding wire using the eyelet and screw provided with the T-Connector.
Locate a suitable grounding point near the adapter such as the vehicle frame or crossmember. Do not drill into the vehicle floor or bed. Do not drill into any exposed surfaces. Before drilling, verify what is behind the surface to avoid damage to the vehicle and personal injury.
The T-Connector has four colored wires: green, yellow, and white. The green and yellow wires are signal wires that connect to the taillight connectors on the passenger and driver sides respectively. The white wire is the ground wire, which must be secured to the vehicle frame or crossmember using the eyelet and screw provided.
Plug the T-Connector end with the yellow wire between the mating plugs on the driver's side taillight socket and vehicle wiring harness. Repeat for the passenger's side using the T-Connector end containing the green wire. Be careful not to damage the locking tabs and ensure that connectors are fully inserted with locking tabs in place. All connections must be complete for the T-Connector to function properly.
Do not exceed the lower of your towing manufacturer's rating or these limits: maximum stop/turn light is 1 per side (2.1 amps); maximum tail lights is 4.2 amps. Overloading the circuit can cause fires. Consult your vehicle's owner's manual and the instruction sheet for additional information.
For the initial test, reset the vehicle electrical system by temporarily removing the key from the ignition. Test and verify the installation with a test light or trailer once installed. All connections must be complete for the T-Connector to function properly.
After installation, reinstall all wheel wells, mud guards, taillights and other items removed during installation, being careful not to pinch or cut the wires. Secure all loose wires with cable ties. Verify that all connections are complete and properly seated with locking tabs in place. Test the installation with a test light or trailer to confirm proper function.
Wear safety glasses and use all safety precautions during installation. Before drilling, verify what is behind any surface to avoid damage to the vehicle and personal injury. Do not drill into any exposed surfaces. Do not drill into the vehicle floor or bed. Be careful not to damage the locking tabs on connectors. Secure all wires with cable ties to prevent damage, rattling, pinching, cutting or melting. Do not exceed the maximum circuit loads (1 stop/turn light per side at 2.1 amps; max tail lights at 4.2 amps) as overloading can cause fires.

Verify that all connections are complete. The T-Connector will not function properly if any connection is incomplete. Check that both the driver-side (yellow wire) and passenger-side (green wire) T-Connector ends are fully plugged into the vehicle's taillight connectors with locking tabs fully seated. Reset the vehicle electrical system by temporarily removing the key from the ignition, then test again with a test light or trailer.
Ensure that all connector surfaces are clean and free of dirt before attempting to connect. Separate the connectors and inspect both the T-Connector ends and the vehicle's taillight connectors for debris or damage. Clean as needed, then carefully reinsert the connectors, being careful not to damage the locking tabs. Push firmly until the connectors are fully inserted with locking tabs in place.
Route the wires carefully to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. Secure all loose wires with the cable ties provided to prevent damage, rattling, and further hazards. When reinstalling wheel wells, mud guards, and taillights, be careful not to pinch or cut the wires. If wires are already damaged, do not proceed; consult the manufacturer or a qualified technician.
