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 T-Connector 118447-037 is designed for Ford Taurus and Mercury Sable vehicles. The manual covers installation for both the driver and passenger sides of these vehicles.
The T-Connector is a taillight wiring interface that connects between the vehicle's taillight wiring harness and trailer lighting. It allows you to tap into the vehicle's stop/turn and tail light circuits without cutting or permanently modifying the factory wiring.
You will need a trim panel puller to remove interior trim panels during installation. A 3/32" drill bit is also required to drill the ground wire hole. No other specialized tools are mentioned in the manual.
The manual does not specify whether the battery should be disconnected. Contact the manufacturer or consult your vehicle's owner's manual for guidance on electrical work safety.
Open the trunk. Temporarily remove the rear threshold plate. Partially remove the felt trunk liner behind the taillights. This provides access to the taillight wiring harness on both sides of the vehicle.
The taillight wiring harness is located on the driver and passenger sides of the vehicle, behind the taillights in the trunk area. It has a connection point on both sides that matches the ends of the T-Connector.
Separate the vehicle's taillight wiring connector carefully, being careful not to break the locking tabs. Ensure all connector surfaces are clean and free of dirt. On the driver side, insert the T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place. Repeat on the passenger side with the T-Connector end containing the green wire. Be sure connectors are fully inserted with locking tabs in place.
The manual does not specify what the yellow and green wires represent. The yellow wire T-Connector end is installed on the driver side and the green wire end on the passenger side, but their function (stop/turn vs. tail light) is not documented.
Yes, drilling is required. You must drill a 3/32" hole near the taillight connector to secure the white ground 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.
Drill a 3/32" hole for the white ground wire. This hole should be located at a suitable grounding point near the connector.
Verify what is behind any surface prior to drilling to avoid damage to the vehicle and/or personal injury. Do not drill into any exposed surfaces. This is critical to prevent hitting hidden wiring, fuel lines, or structural components.
Route the T-Connector end with the green wire to the passenger's side behind the panels and along the threshold. The 4-flat connector should be routed from below the threshold plate into the trunk and stored there when not in use. Be careful not to pinch or cut the wires when reinstalling trim panels and the threshold.
The 4-flat connector is the trailer connector end of the T-Connector assembly. It should be routed from below the threshold plate into the trunk and stored there when not in use. This keeps it protected and accessible for connecting a trailer.
After all connections are complete, reinstall the felt trunk liner, threshold plate, and other items removed during installation. Be careful not to pinch or cut the wires. Then test and verify the installation with a test light or by connecting a trailer to ensure all connections are functioning properly.
Do not exceed 7.5 amps for stop/turn lights and 7.5 amps for tail lights. These are the maximum ratings for the T-Connector. Do not exceed the lower of the vehicle manufacturer's rating or these limits, as overloading the circuit can cause fires.
Overloading the circuit can cause fires. Do not exceed the lower of the vehicle manufacturer's rating or the maximum amperage limits: 7.5 amps for stop/turn lights and 7.5 amps for tail lights. Consult your vehicle's owner's manual for additional information on electrical system capacity.
Test and verify the installation with a test light or by connecting a trailer once installed. All connections must be complete for the T-Connector to function properly. This ensures that the stop/turn and tail light circuits are working correctly before towing.
All connector surfaces should be clean and free of dirt to ensure proper electrical contact and function of the T-Connector. Dirt or corrosion on the connector surfaces can prevent the T-Connector from working correctly.
Be careful not to damage the locking tabs when inserting the T-Connector. Ensure that connectors are fully inserted with locking tabs in place. If the locking tabs are broken, the connection may not be secure and the T-Connector will not function properly.

The BRAKE mate is a trailer brake control system that allows you to control trailer brakes from your vehicle. It connects to your vehicle's electrical system and includes a brake control unit that mounts under the dash, circuit breakers for power management, and a prewired connector that attaches to your trailer.
The manual does not specify which vehicle makes, models, or years are compatible with the BRAKE mate. Contact Cequent Towing Products technical service at (888) 521-0510 or consult a fitment database to confirm compatibility with your specific vehicle.
Yes. Step 4 of the installation instructions requires connecting the 4-pole flat connector to the vehicle's connector, which means your vehicle must already have a 4-pole flat connector. If your vehicle does not have one, the BRAKE mate cannot be installed using these instructions.
The kit includes: 1 prewired connector, 1 heavy duty flasher, 1 20 amp circuit breaker, 1 40 amp circuit breaker, 5 #10 G-ring connectors, 2 3/8" G-ring connectors, 5 Scotch locks, 8 self-tapping screws, and 6 wire tie straps.
The manual does not specify required tools. However, based on the installation steps, you will likely need a drill (to create a firewall hole if one does not exist), wire strippers, a screwdriver (for self-tapping screws), and possibly a crimper or pliers for ring connectors. Contact technical service at (888) 521-0510 for a complete tool list.
The manual does not specify whether the battery must be disconnected before installation. Contact Cequent Towing Products technical service at (888) 521-0510 for safety guidance before beginning work.
Mount the bracket for the round connector on the bumper if that is where you intend to install it. Some hitches have built-in brackets, so check your hitch first before mounting a separate bracket.
Mount the brake control unit under the dash onto something firm. The unit must be securely fastened to a solid surface.
Mount the 2 circuit breakers (20 amp and 40 amp) end to end on the firewall within reach of the BLUE/BLACK cable. Secure them with the self-tapping screws supplied in the kit.
You may need to drill a hole through the firewall to run the BLUE/BLACK 2-strand wire from the engine bay into the cab. Look for an existing spot first; if none is available, drill a hole and seal it with a rubber grommet or silicone to prevent water and debris from entering the cab.
Some hitch brackets may need to be cut to allow the various connectors to pass through. Check your specific hitch bracket during installation; if it blocks connector passage, you will need to cut it.
Yes. In step 9, you must cut the black wire to create two open ends. These ends are then fitted with ring connectors and attached to the 40 amp and 20 amp circuit breakers respectively.
WHITE = ground wire; BLUE/BLACK = 2-strand power and trailer brake wire (runs from rear connector to front of vehicle and through firewall); RED = power wire from brake control unit; BLUE = trailer brake wire from brake control unit; GREEN = wire from brake control unit to brake switch.
Connect the WHITE ground wire to the frame of the vehicle. This provides the ground connection for the system.
Run the BLUE/BLACK 2-strand wire along the frame rail to the front of the vehicle, avoiding the exhaust, axles, and brake cables. Secure it with the plastic tie straps supplied. Then run it up the firewall, avoiding the steering mechanism, and secure it with ties.
Split the BLUE/BLACK 2-strand wire down the middle. Connect the RED (power) wire of the brake control unit to the BLACK wire using a Scotch lock. Connect the BLUE (trailer brake) wire of the brake control unit to the BLUE wire using a Scotch lock. Connect the WHITE wire of the brake control unit to the ground on the vehicle body. Connect the GREEN wire of the brake control unit to the inactive side of the brake switch.
Run a heavy gauge wire from the battery or equivalent power source to the battery side of either circuit breaker. Attach a #10 G-ring connector to one end of the wire. Then split a wire off this main wire to the 20 amp breaker using a Scotch lock and attach a #10 G-ring connector to the end of this wire. Alternatively, you can run a jumper between the two breakers.
The circuit breakers protect the electrical system. The 40 amp breaker is connected to the auxiliary side of the wire going to the rear connector. The 20 amp breaker is connected to the auxiliary side of the wire going through the firewall to the brake control unit.
The heavy duty flasher is a replacement turn signal flasher. If your turn signals blink too fast after installation, replace your vehicle's original turn signal flasher with the one supplied in the kit.
After attaching the round connector with self-tapping screws, test the connector for: running lights, brake lights, turn signals, and hot wire (power). Note that the brake control output cannot be tested unless a trailer is connected to the connector.
If the turn signals are blinking too fast after installation, replace the turn signal flasher with the heavy duty flasher supplied in the BRAKE mate kit.
After drilling a hole through the firewall to run the BLUE/BLACK wire into the cab, seal the hole with a rubber grommet or silicone to prevent water and debris from entering the vehicle.
When running the BLUE/BLACK 2-strand wire along the frame rail and up the firewall, avoid the exhaust, axles, brake cables, and steering mechanism. These components can damage the wire or be damaged by it. Secure the wire with the supplied plastic tie straps.
Your vehicle must have a 4-pole flat connector. Contact Cequent Towing Products at (888) 521-0510 or check a fitment database to confirm compatibility with your specific make, model, and year.

You may need to drill a hole through the firewall to run the brake wire into the cab if an existing hole is not available. The hole must be sealed with a rubber grommet or silicone.
Connect WHITE (ground) to frame, RED (power) to BLACK wire, BLUE (trailer brake) to BLUE wire, GREEN to brake switch, and run BLUE/BLACK from rear connector through firewall to brake control unit.
Test for running lights, brake lights, turn signals, and hot wire (power). Brake control output cannot be tested without a trailer connected. If turn signals blink too fast, replace the flasher with the one supplied.
Avoid routing the BLUE/BLACK wire near the exhaust, axles, brake cables, or steering mechanism. Secure all wires with the supplied plastic tie straps.
