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 T-One® T-Connector is a trailer wiring harness system designed for the Acura TLX. It provides a connection point between the vehicle's taillight wiring and a trailer's electrical system, allowing the trailer lights to operate from the vehicle's electrical system. The system includes a black box module, T-connectors with color-coded wires (yellow, brown, green, white, and black), a fuse holder with a 15 amp fuse, cable ties, and hardware for installation.
Yes, the T-One® T-Connector (part number 118697-037) is designed specifically for the Acura TLX. The manual provides installation instructions tailored to this vehicle's taillight configuration and electrical system.
You will need: a trim panel remover, a drill with a 3/32" drill bit, a Phillips head screwdriver, a test probe, a 10 mm socket or wrench, wire crimpers, and wire cutters. These tools are required to remove trim panels, drill the ground wire hole, disconnect and reconnect connectors, and prepare the wiring harness.
The kit includes: a black box module (T-One® T-Connector), T-connectors with color-coded wires (yellow, brown, and green), a white ground wire with an eyelet and screw, a black 12 gauge wire, a yellow fuse holder with a 15 amp fuse, yellow butt connectors, a ring terminal, cable ties, and a 4-flat connector for storage in the trunk when not in use.
Yes. You must disconnect the vehicle's negative (-) battery cable before connecting the fuse holder to the positive battery terminal. This is a safety requirement to prevent electrical shock or short circuits during installation. After all connections are complete, you reconnect the negative battery cable and install the 15 amp fuse into the fuse holder.
Yes. You must remove the taillights on both the driver and passenger sides of the vehicle to access the taillight wiring harness. When removing them, carefully pull the taillights away from the vehicle and be careful not to damage the alignment pins. The taillights are reinstalled at the end of the installation process.
Yes. You must temporarily remove the rear threshold plate and partially remove the felt trunk liner behind the taillights to access the grommet and route the T-connector wiring harness. These items are reinstalled at the end of the installation process, being careful not to pinch or cut the wires.
Yes. You must drill a 3/32" hole to secure the white ground wire. Before drilling, you must verify what is behind the surface to avoid damage to the vehicle and/or personal injury, and you must not drill into any exposed surfaces. The hole is drilled at a suitable grounding point near the connector after cleaning dirt and rustproofing from the area. The white wire is then secured using the eyelet and screw provided.
Yes. On the driver's side, you must slit the grommet enough to allow the trailer wiring harness access to the taillight assemblies. After routing the T-connector with yellow and brown wires through the grommet, you reseat the grommet. The same process is repeated on the passenger's side for the T-connector end with the green wire.
The T-One® T-Connector uses color-coded wires: yellow wire connects to the driver's side 2-pin connector; brown wire connects to the driver's side 3-pin connector; green wire connects to the passenger's side (repeating the same connections as the driver's side); white wire is the ground wire, drilled and secured to a grounding point; and black wire connects to the vehicle's positive battery terminal through a 15 amp fuse holder. The black wire from the T-One® black box module is connected to the vehicle's black 12 gauge wire using a yellow butt connector.
A 15 amp fuse is used in the T-One® T-Connector. The fuse is installed in the yellow fuse holder provided with the kit and is connected between the black 12 gauge wire and the vehicle's positive (+) battery cable. The fuse protects the circuit from overload.
From inside the vehicle, connect the black 12 gauge wire from the T-One® black box to the vehicle's black 12 gauge wire using the supplied yellow butt connector. Then route the black wire either through a grommet and along the exterior frame, or follow the existing wiring along the thresholds into the engine compartment up to the battery. Avoid areas that may pinch or break the wire. If routing through a grommet and along the exterior, be careful to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
After disconnecting the vehicle's 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. Then reconnect the vehicle's negative (-) battery cable and install the 15 amp fuse into the fuse holder. Do not exceed the product ratings or towing manufacturing rating stated in your vehicle owner's manual.
On the driver's side, locate and disconnect the black 2-pin connector, then insert the T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place, ensuring connectors are fully inserted with locking tabs in place. Then locate and disconnect the black 3-pin connector and insert the T-Connector end with the brown wire between the vehicle wiring connectors and lock into place. Repeat this process on the passenger's side using the T-Connector end with the green wire, connecting to the same connector types.
Always 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/or personal injury, and do not drill into exposed surfaces. When routing wires, avoid hot pipes, heat shields, the fuel tank, or any points that may pinch or break the wire. Do not exceed the product ratings or towing manufacturing rating stated in your vehicle owner's manual, as overloading circuits can cause fires. Read and follow all warnings and cautions printed on the tow vehicle's battery.
All connections must be complete for the T-One® T-Connector to function properly. Test and verify the installation with a test light or trailer once installed. For the initial test, reset the vehicle electrical system by temporarily removing the key from the ignition. This ensures all connections are working correctly before towing.
Locate a flat surface in an out-of-the-way place and mount the T-One® black box module to prevent damage or rattling. The module should be secured away from areas where it could be struck or cause interference with vehicle operation.
Secure the remainder of the T-One® T-Connector harness with the cable ties provided to prevent damage or rattling. Be careful to avoid any areas that would pinch, cut, or melt the wire. When reinstalling the taillight housing assemblies, position the vehicle wiring harness between the housing and the vehicle body, and be careful not to pinch or cut the wires.
Store the 4-flat connector in the trunk area when not in use. This protects it from damage and keeps it readily available for when you need to tow.
Yes, the T-One® T-Connector (part number 118697-037) is designed specifically for the Acura TLX.
Yes, you must disconnect the vehicle's negative (-) battery cable before connecting to the positive terminal. Reconnect it after all connections are complete and the 15 amp fuse is installed.
A 15 amp fuse is used in the yellow fuse holder provided with the kit.
Do not exceed the product ratings or towing manufacturing rating stated in your vehicle owner's manual. Overloading circuits can cause fires. Always wear safety glasses during installation.
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.
The kit includes a prewired connector, brake control unit, 20 amp and 40 amp circuit breakers, 5 #10 G-ring connectors, 2 3/8" G-ring connectors, 5 Scotch locks, 8 self-tapping screws, 6 wire tie straps, and a heavy duty flasher.
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.
