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-One® Connector is a trailer wiring harness designed for the Volvo XC70. It integrates with the vehicle's existing taillight wiring to provide trailer lighting connections. The connector includes a black box module, multiple wire leads (yellow, green, red, white, and black), and a 4-flat connector for the trailer. It allows you to connect a trailer's lighting system to your vehicle's electrical system.
Yes, the T-One® Connector part number 118774-037 is designed specifically for the Volvo XC70. The installation instructions are tailored to this vehicle's rear cargo area layout, taillight wiring harness location, and battery access.
You will need: trim panel remover, 10mm socket and ratchet or 10mm wrench, drill with 3/32" drill bit, wire crimpers, wire cutters, Phillips head screwdriver, and a test probe. Safety glasses are also required during installation.
The kit includes: the T-One® Connector black box module, wire leads (yellow, green, red, white, and black 12 ga. power wire), double-sided tape for mounting the black box, cable ties for securing the harness, an eyelet and screw for the white ground wire, a yellow fuse holder with a 15 amp fuse, a yellow butt connector, and a 4-flat connector for storage in the rear cargo area when not in use.
Yes. You must disconnect the vehicle's negative (-) battery cable before connecting the power wire to the positive battery terminal. This is done in step 10 of the installation. After all connections are complete and the fuse is installed, you reconnect the negative battery cable in step 12.
You must partially remove the plastic threshold cover, side panels, and cargo trays from the rear cargo area to locate the vehicle's taillight wiring harness. These items are reinstalled at the end of the installation in step 13.
The T-One® Connector integrates into the existing taillight wiring on both sides of the vehicle. On the driver's side, insert the connector end with the yellow wire between the vehicle's taillight connectors and lock into place (step 3). On the passenger's side, insert the connector end with the green wire between the vehicle's taillight connectors and lock into place (step 7). On the driver's side, route the connector end with the red wire up the side panel to the mating connector and lock in place (step 8). Ensure all locking tabs are fully engaged and connector surfaces are clean before connecting.
Mount the black box on the driver's side of the vehicle using the double-sided tape provided. The box should be positioned near the taillight wiring connectors. After mounting, secure the remainder of the harness with the cable ties provided, being careful to avoid areas that would cut or pinch the wire.
Locate the black 12 ga. power wire from the T-One® Connector box on the driver's side. Route the black wire 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 of the vehicle, carefully avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
Yes, drilling is required to install the ground wire. You must drill a 3/32" hole to secure the white ground wire using the eyelet and screw provided, unless a suitable existing ground stud is available near the connector. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into the vehicle floor or bed. Clean dirt and rustproofing from the area before securing the wire.
A 3/32" drill bit is required to drill the hole for securing the white ground wire.
Install a 15 amp fuse into the fuse holder. The yellow fuse holder is provided with the kit. If the fuse was removed from the holder before installation, reinstall it in step 12 after all connections are complete.
The T-One® Connector includes five main wires: yellow wire (driver's side taillight connection), green wire (passenger's side taillight connection), red wire (driver's side mating connector), white wire (ground connection to vehicle frame), and black 12 ga. wire (power connection to vehicle battery positive terminal). Each wire is routed to a specific location on the vehicle as detailed in steps 3-10.
After disconnecting the vehicle's negative battery cable, locate the black 12 ga. power wire from the T-One® Connector box. Remove the fuse from the yellow fuse holder if not already removed. 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 ga. wire using the yellow butt connector provided. Reconnect the vehicle's negative battery cable and install the 15 amp fuse into the fuse holder.
The yellow fuse holder protects the power circuit. It is installed between the vehicle's positive battery cable and the black 12 ga. power wire from the T-One® Connector. A 15 amp fuse is installed in the holder to protect the circuit from overload. The fuse holder is connected to the battery in step 10 and the fuse is installed in step 12 after all other connections are complete.
Always 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. When routing the power wire, avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. Secure all wires with cable ties to prevent damage or rattling. Read and follow all warnings and cautions printed on the tow vehicle's battery. Do not exceed the towing manufacturer's rating or the product's amperage ratings, as overloading circuits can cause fires.
After installation is complete, test and verify the installation with a test light or trailer. For the initial test, reset the vehicle's electrical system by temporarily removing the key from the ignition. All connections must be complete for the T-One® Connector to function properly.
After all wiring is complete and tested, reinstall the plastic trim panels, threshold, storage covers, floor covering, and other items that were removed during installation. Be careful not to pinch or cut the wires when reinstalling these components. Store the 4-flat connector in the rear cargo area when not in use.
Do not exceed the lower of the towing manufacturer's rating (including in your vehicle owner's manual) or the specific amperage ratings stated on the product. The manual does not specify the product's amperage rating; refer to the product label or contact the manufacturer for this specification. Overloading circuits can cause fires.
