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, the 2005-2006 Mazda Tribute, 2005-2007 Ford Escape Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118426 (Part #TK118426) is designed to fit the 2005-2007 Ford Escape.
The 2005-2006 Mazda Tribute, 2005-2007 Ford Escape Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118426 (Part #TK118426) Drilling is required for installation. Basic hand tools are typically all you need.
Yes, the T-Connector is designed for both Mazda Tribute and Ford Escape vehicles. The installation procedure is the same for both models.
The T-Connector is a trailer wiring harness that connects to your vehicle's taillight system to provide power for trailer lights. It intercepts the vehicle's taillight signals and routes them to a 4-flat connector for trailer use.
You will need: a drill with a 3/32" drill bit, a Philips head screwdriver, pliers, wire crimpers, and wire cutters.
The kit includes: the T-Connector black box with yellow, red, and green wires; a 4-flat connector; a 10 amp fuse and yellow fuse holder; a white wire with eyelet and screw for grounding; yellow butt connectors; double-sided tape; and cable ties. A bracket for the 4-flat connector is not included.
Yes. You must disconnect the vehicle's negative (-) battery cable before beginning installation. This is done in Step 6 before connecting the fuse holder to the positive battery cable.
Yes. You must open the rear liftgate and remove two screws on both the driver and passenger sides to pull the taillight assemblies away from the vehicle. Be careful not to damage the alignment pins when removing them.
Yes. You must drill a 3/32" hole to secure the white ground wire to the vehicle frame or crossmember. Before drilling, verify what is behind the surface to avoid damaging the vehicle or causing injury. Do not drill into the vehicle floor or bed, and do not drill into any exposed surfaces.
The T-Connector has four wires: yellow wire connects to the center gray taillight socket; red wire connects to the top black taillight socket; green wire is routed to the passenger side taillight; and a black 12 gauge wire connects to the vehicle's positive battery cable through a fuse holder. A white wire provides the ground connection to the vehicle frame.
A 10 amp fuse is required. The fuse is installed in the yellow fuse holder provided with the kit and is connected to the vehicle's positive (+) battery cable.
On both driver and passenger sides: disconnect the center gray taillight socket and plug the T-Connector with the yellow wire between the separated halves. Then disconnect the top black taillight socket and plug the T-Connector with the red wire between those halves. Ensure connectors are fully inserted with locking tabs in place. Be careful not to break the locking tabs when disconnecting.
Locate a suitable grounding point near the connector, such as the vehicle's frame or crossmember. Clean dirt and rustproofing from the area using a mixture of rubbing alcohol and water. Drill a 3/32" hole and secure the white wire using the eyelet and screw provided. Do not drill into the vehicle floor or bed.
After disconnecting the negative battery cable, cut the fuse holder wire and attach the ring terminal to the vehicle's positive (+) battery cable. Connect the other end of the fuse holder to the black 12 gauge wire using the yellow butt connector provided. The 10 amp fuse is installed in the fuse holder after all other connections are complete.
Beginning from the front of the vehicle, route the black 12 gauge wire rearward along the frame rail toward the rear driver's side. Be careful to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. Route the wire up through the opening between the vehicle rear bumper and body to access the rear driver's side taillight area.
On the driver's side, route the T-Connector end with the green wire and the 4-flat connector wire down through the opening between the vehicle bumper and body. Route the green wire to the passenger's side and route the 4-flat underneath the bumper. On the passenger side, route the green wire up through the opening, being careful to avoid areas that could damage wiring. Then connect the green wire to the passenger side taillight following Step 2 procedure.
Mount the T-Connector black box behind the taillight assembly on the driver's side. Clean a flat area using a mixture of rubbing alcohol and water, then mount the black box using the double-sided tape provided.
Mount the 4-flat connector in a suitable location under the vehicle. The manual does not specify an exact location. A bracket is not included with the kit, so you will need to source one separately.
Secure all loose wiring using the cable ties provided. When reinstalling the taillight housing assemblies, position the vehicle wiring harness between the housing and the vehicle body. Secure the remainder of the T-Connector harness with cable ties to prevent damage or rattling, being careful to avoid any areas that would cut or pinch the wire.
Do not exceed the lower of your towing manufacturer's rating or: maximum stop/turn light of 1 per side (2.1 amps) and maximum tail lights of 4.2 amps. Overloading the circuit can cause fires. Consult your vehicle's owner's manual and instruction sheet for additional information.
Wear safety glasses during installation. Before drilling, verify what is behind any surface to avoid damage to the vehicle or personal injury. Do not drill into exposed surfaces, the vehicle floor, or bed. Route all wires carefully to avoid hot pipes, heat shields, the fuel tank, or any points that may pinch or break the wire. Ensure all connections are complete before testing.
After installation is complete, test and verify the installation with a test light or by connecting an actual trailer. All connections must be complete for the T-Connector to function properly. This testing should be done after the 10 amp fuse has been installed and the negative battery cable has been reconnected.
1. Open rear liftgate and remove taillight assemblies. 2. Disconnect taillight sockets and connect T-Connector yellow and red wires. 3-4. Route green wire and 4-flat connector through vehicle. 5. Install ground wire to frame. 6. Disconnect negative battery cable and connect fuse holder to positive battery cable. 7-8. Route black 12 gauge wire from battery to rear and connect to red wire. 9. Reconnect negative battery cable and install 10 amp fuse. 10. Mount black box behind driver's side taillight. 11. Reinstall taillight assemblies and secure all wiring with cable ties.
Yes, the T-Connector (118426-037) is designed for both Mazda Tribute and Ford Escape vehicles.
You need a drill with 3/32" bit, Philips head screwdriver, pliers, wire crimpers, and wire cutters.
A 10 amp fuse is required, installed in the yellow fuse holder provided with the kit.
