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 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.
The T-Connector is a wiring harness that integrates with your Toyota Prius's taillight wiring to provide a connection point for trailer lighting. It includes a black box module, color-coded wires (green, yellow, and white), a fuse holder with a 10 amp fuse, double-sided tape, cable ties, and grounding hardware (eyelet and screw). The connector allows you to safely control trailer lights through your vehicle's existing electrical system.
Yes, the T-Connector is designed for the Toyota Prius. The manual does not specify model years or trim levels, so contact the manufacturer or your installer to confirm compatibility with your specific Prius generation and year.
No. The T-Connector is designed for use only with 12V battery systems. Do not attempt to use it with any other voltage system.
You will need: trim panel remover, 10 mm socket and ratchet or 10 mm wrench, drill with 3/32" drill bit, 1/4" socket, wire crimpers, wire cutters, Phillips head screwdriver, and a test probe. Safety glasses are also required.
The T-Connector includes: a black box module, color-coded wires (green, yellow, white), a fuse holder with a 10 amp fuse, double-sided tape for mounting the black box, cable ties for securing the harness, an eyelet and screw for grounding the white wire, and a 4-flat connector for storage in the spare tire compartment when not in use.
Yes. You must disconnect and isolate the vehicle's negative (−) battery terminal before beginning installation. The battery is located inside the cargo area on the passenger side, underneath the floor covering in the rear corner. After connecting the fuse holder to the positive terminal, you will reconnect the negative battery cable and install the 10 amp fuse. See your vehicle's owner's manual for any special battery reconnection instructions.
The 12-volt battery is located inside the cargo area on the passenger side, underneath the floor covering in the rear corner.
Open the trunk/hatch and locate the vehicle wiring inside the rear cargo area by partially removing the plastic threshold cover, side access panels, carpet panels, and cargo trays. On both the driver and passenger sides, you will find the taillight wiring harness with connection points that match the ends of the T-Connector.
1. Locate the taillight wiring harness on both driver and passenger sides. 2. Separate the connector carefully without breaking the locking tabs. Ensure all connector surfaces are clean and free of dirt. 3. On the passenger side, insert the T-Connector end with the green wire between the vehicle wiring connectors and lock into place. 4. Route the T-Connector end with the yellow wire to the driver's side behind the panels and along the threshold. 5. Repeat for the T-Connector end with the yellow wire on the driver's side.
On the passenger side, locate a suitable grounding point near the connector. You have two options: Option 1: Clean dirt and rustproofing from the area, drill a 3/32" hole, and secure the white wire using the eyelet and screw provided. Do not drill into the vehicle floor, bed, or any exposed surfaces. Option 2: Locate an existing ground stud, loosen the bolt, place the screw eyelet on the stud, and re-tighten the bolt. Before drilling, verify what is behind any surface to avoid damage to the vehicle and personal injury.
1. Attach the fuse holder (with fuse removed) to the positive (+) terminal of the battery. 2. Reconnect the vehicle's negative (−) battery cable. 3. Install the 10 amp fuse into the fuse holder. See your vehicle's owner's manual for any special battery reconnection instructions.
On the passenger side, mount the T-Connector black box using the double-sided tape provided. Secure the remainder of the T-Connector harness with the cable ties provided to prevent damage or rattling. Be careful to avoid any areas that would cut or pinch the wire.
Store the 4-flat connector in the spare tire compartment when not in use.
Drilling may be required depending on your grounding option. If you choose Option 1 for the white ground wire, you must drill a 3/32" hole to secure the eyelet and screw. If you choose Option 2 and use an existing ground stud, no drilling is required. Before drilling, verify what is behind any surface to avoid damage to the vehicle and personal injury. Do not drill into the vehicle floor, bed, or any exposed surfaces.
Drill a 3/32" hole for the white ground wire eyelet. Before drilling, verify what is behind the surface to avoid damage to the vehicle and personal injury. Do not drill into the vehicle floor, bed, or any exposed surfaces.
The T-Connector uses a 10 amp fuse. This fuse protects the circuit and must be installed in the fuse holder that connects to the vehicle's positive battery terminal.
Do not exceed the lower of your vehicle manufacturer's rating or: maximum stop/turn light: 1 per side (2.1 amps); maximum tail lights: 5.6 amps. Overloading the circuit can cause fires. Read your vehicle's owner's manual and instruction sheet for additional information.
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 the vehicle floor, bed, or any exposed surfaces. Read and follow all warnings and cautions printed on the tow vehicle's battery. Ensure all connector surfaces are clean and free of dirt before connecting. Be careful not to pinch or cut wires when reinstalling trim panels and floor coverings.
All connections must be complete for the T-Connector to function properly. Test and verify 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.
After installation, verify that: all connections are complete and secure; the T-Connector black box is mounted securely with double-sided tape on the passenger side; all wires are secured with cable ties and routed to avoid pinching or cutting; all trim panels, threshold, storage covers, and floor covering are reinstalled without pinching or cutting wires; and the 4-flat connector is stored in the spare tire compartment when not in use. Test the installation with a test light or trailer and reset the vehicle electrical system by temporarily removing the ignition key.
Yes. Disconnect and isolate the negative battery terminal before installation. The battery is in the cargo area on the passenger side under the floor covering. Reconnect it after attaching the fuse holder to the positive terminal.
