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-One T-Connector is designed for Jeep Grand Cherokee. The installation involves connecting to the vehicle's taillight wiring via T-connectors inserted between the vehicle's existing connectors, and routing a 4-flat connector harness underneath the vehicle to a tow point.
You will need: trim panel remover, 10mm socket & ratchet or 10mm wrench, drill with 3/32" bit, 1/4" socket, wire crimpers, wire cutters, Phillips head screwdriver, and test probe.
Yes. You must disconnect the vehicle's negative (-) battery cable before connecting the fuse holder to the positive battery terminal in step 7. Reconnect the negative cable after installing the 15 amp fuse in step 8.
Yes. You must drill a 3/32" hole for the ground wire connection. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into any exposed surfaces.
Install a 15 amp fuse into the yellow fuse holder provided with the kit.
Test and verify the installation with a test light or trailer. For the initial test, reset the vehicle electrical system by temporarily removing the key from the ignition. Do not exceed the product's stated amperage ratings or the towing manufacturing rating in your vehicle owner's manual.
The T-One T-Connector is a wiring harness that connects your Jeep Grand Cherokee's taillight system to a trailer connector. It uses T-shaped connectors that insert between your vehicle's existing taillight wiring connectors, allowing you to plug in a trailer without modifying the vehicle's original wiring. The system includes a black box module, a 4-flat connector for the trailer, and all necessary wiring and fasteners.
Yes. The T-Connector is designed to work with your vehicle's factory taillight connectors. It uses a black 3-pin connector (with yellow wire) and a black 2-pin connector (with brown wire) that insert between your vehicle's existing wiring connectors. The connectors must be fully inserted with locking tabs in place to function properly.
Yes. You must open the rear tailgate and remove both the driver's side and passenger's side taillights to access the taillight connectors. Remove the two clips holding each taillight in place and carefully pull the taillight away from the vehicle, being careful not to damage the alignment pins. You will reinstall them after connecting the T-Connector.
After removing the taillights, locate the black 3-pin connector behind the taillight housing and separate the vehicle's wiring connectors carefully without breaking the locking tabs. Ensure all connector surfaces are clean and free of dirt. Insert the T-Connector end with the yellow wire between the vehicle's wiring connectors and lock into place, ensuring connectors are fully inserted with locking tabs secured. Repeat this process with the black 2-pin connector using the T-Connector end with the brown wire.
On the driver's side, route the T-Connector end with the green wire and the wire with the 4-flat connector down through the opening between the vehicle bumper and body. Route the T-Connector end with the green wire up through the opening on the passenger side, being careful to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. The 4-flat harness should be routed underneath and to the center of the vehicle.
Locate a suitable grounding point near the connector. Clean dirt and rustproofing from the area. Drill a 3/32" hole and secure the white wire using the eyelet and screw provided. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury, and do not drill into any exposed surfaces.
Locate the battery in the vehicle's trunk. From inside the vehicle, connect the black 12 ga. wire and the black wire from the T-Connector black box using the supplied yellow butt connector. Then disconnect the vehicle's negative (-) battery cable. Remove the fuse from the yellow fuse holder (if not already removed), cut the fuse holder wire, attach the ring terminal to the vehicle's positive (+) battery cable, and connect the other end of the fuse holder to the black 12 ga. wire using the yellow butt connector. Finally, reconnect the negative battery cable and install the 15 amp fuse into the fuse holder.
The T-Connector uses the following wire colors: yellow wire (connects to the black 3-pin taillight connector), brown wire (connects to the black 2-pin taillight connector), green wire (routed through the vehicle to the passenger side), white wire (ground connection), black wire (battery connection via the black box module), and the 4-flat connector (trailer connection). All connectors must be fully inserted with locking tabs in place.
Locate a flat surface in an out-of-the-way place and mount the T-One T-Connector's black box module to prevent damage or rattling. The location should be accessible but protected from impact.
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. The 4-flat end should be mounted in an accessible location with a bracket or electrical box (not included).
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 or personal injury. Do not drill into exposed surfaces. Read and follow all warnings and cautions printed on the tow vehicle's battery. Do not exceed the product's stated amperage ratings or the towing manufacturing rating in your vehicle owner's manual, as overloading circuits can cause fires.
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. All connections must be complete for the T-One T-Connector to function properly.
Before inserting the T-Connector, separate the vehicle's wiring connectors carefully, being careful not to break the locking tabs. Ensure all connector surfaces are clean and free of dirt. This applies to both the black 3-pin connector and the black 2-pin connector.
No permanent modifications to factory wiring are required. The T-Connector uses T-shaped connectors that insert between your vehicle's existing taillight connectors without cutting or splicing the original wires. The only cutting required is to the yellow fuse holder wire when connecting to the positive battery terminal, which is part of the provided fuse holder assembly.
The kit includes: T-Connector adapters with yellow, brown, and green wires; a black box module; a 4-flat connector harness; a white ground wire with eyelet and screw; a black 12 ga. wire; yellow butt connectors; a yellow fuse holder with 15 amp fuse; a ring terminal; and cable ties for securing the harness.
The 4-flat connector is the trailer connection point. It should be routed underneath and to the center of the vehicle and mounted in an accessible location with a bracket or electrical box (not included). This is where you will plug in your trailer connector.
First, verify that all connections are complete and secure. Check that the T-Connector ends with the yellow and brown wires are fully inserted into the vehicle's taillight connectors with locking tabs in place. Ensure the black 12 ga. wire and black wire from the black box module are connected with the yellow butt connector. Verify that the 15 amp fuse is installed in the yellow fuse holder and that the negative battery cable is reconnected. Reset the vehicle electrical system by temporarily removing the key from the ignition. Test with a test light or trailer to verify proper function.
Ensure that the connector surfaces are clean and free of dirt before inserting the T-Connector. Verify that you are inserting the T-Connector ends fully between the vehicle's wiring connectors. The locking tabs must be fully engaged and in place. If the locking tabs are damaged, do not attempt to force the connector. Consult the manufacturer for replacement connectors.
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.
