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.
Yes, the T-Connector 118646-037 is designed for Volkswagen Golf. The manual does not specify model year range or trim variations, so contact the manufacturer or your installer to confirm fitment for your specific vehicle year and configuration.
The T-Connector is a wiring harness that integrates with your vehicle's existing taillight connectors to provide trailer lighting control. It uses a black box module and connects to your vehicle's battery to manage stop, turn and tail light signals for a trailer. The 4-flat connector is stored in the rear cargo area when not in use.
Required tools are: trim panel remover, 10 mm socket and ratchet or 10 mm wrench, drill with 3/32" bit, 1/4" socket, wire crimpers, wire cutters, Phillips head screwdriver, and test probe. You will also need safety glasses.
The T-Connector kit includes: two T-Connector ends (one with yellow wire, one with green wire), a black box module, cable ties, a yellow fuse holder with fuse, a ring terminal, a screw for the ground wire eyelet, an eyelet, and yellow butt connectors for joining wires.
Yes. You must disconnect the vehicle's negative (−) battery cable before making the final electrical connections to the positive battery terminal. This is a safety requirement to prevent electrical shock or short circuits during installation.
You must remove the threshold, trunk floor panels and trays from the rear cargo area. You must also partially remove the rear interior trim panels on both the driver and passenger sides of the vehicle. Several trim panel fasteners will need to be removed. Set all removed items aside carefully to avoid damage.
On the driver's side, separate the vehicle's wiring connectors carefully without breaking the locking tabs. Insert the T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place. Ensure all connector surfaces are clean and free of dirt. Repeat this process on the passenger's side using the T-Connector containing the green wire, routing it below the threshold cover to the passenger's side taillight housing.
Yes. You must drill a 3/32" hole on the driver's side near the connectors to create a grounding point for the white wire. The white wire is secured to this hole using an eyelet and the 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.
Use a 3/32" drill bit to create the hole for the ground wire on the driver's side near the connectors.
The T-Connector uses four wire colours: yellow wire (driver's side taillight connector), green wire (passenger's side taillight connector), white wire (ground connection), and black wires (12 gauge power connection to battery). The yellow and green wires connect to the vehicle's existing taillight connectors. The white wire grounds to the vehicle frame. The black wires carry 12-volt power from the battery through the fuse holder.
From inside the vehicle, connect the black 12-gauge wire from the T-Connector black box module to the black 12-gauge wire using the supplied yellow butt connector. You may 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, avoid hot pipes, heat shields, the fuel tank or other points that may pinch or break the wire.
The yellow fuse holder is a protective device supplied with the T-Connector. After disconnecting 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 secure it. Connect the other end of the fuse holder to the black 12-gauge wire using the supplied yellow butt connector. This protects the circuit from overload.
Locate a flat surface in an out-of-the-way place and mount the T-Connector's black box module to prevent damage or rattling. The manual does not specify an exact location, so choose a secure spot away from moving parts, heat sources and areas where it could be damaged.
Secure the remainder of the T-Connector harness with the cable ties provided to prevent damage, rattling and noise. Be careful to avoid any areas that would pinch, cut or melt the wire. After securing the harness, reinstall all plastic trim panels, threshold, storage covers, floor covering and other items that were removed during installation, being careful not to pinch or cut the wires.
Do not exceed the lower of your towing manufacturer's rating or these limits: maximum stop/turn light 2 per side (4.2 amps), maximum tail lights (7.5 amps). Overloading the circuit can cause fires. Consult your vehicle's owner's manual and instruction sheet for additional information on your specific towing capacity.
After installation is complete, test and verify the installation with a test light or by connecting an actual 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-Connector to function properly. Use a test probe to verify proper operation of all lights.
Store the 4-flat connector in the rear cargo area when not in use.
Wear safety glasses during installation. Read and follow all warnings and cautions printed on the vehicle's battery and in the vehicle's owner's manual. Before drilling, verify what is behind any surface to avoid damage to the vehicle or personal injury. Do not drill into exposed surfaces. When routing wires, avoid hot pipes, heat shields, fuel tank and other points that may pinch, cut or melt the wire. Use all safety precautions during installation.
The T-Connector 118646-037 is designed for Volkswagen Golf. Confirm your specific model year and configuration with the manufacturer or installer before purchasing.
You need: trim panel remover, 10 mm socket/ratchet or wrench, drill with 3/32" bit, 1/4" socket, wire crimpers, wire cutters, Phillips screwdriver, test probe, and safety glasses.
Yes, you must disconnect the vehicle's negative (−) battery cable before making final electrical connections to the positive battery terminal.
The power connection uses black 12-gauge (12 ga.) wire routed through a yellow fuse holder to the vehicle's positive (+) battery terminal.
First, verify that all connections are complete and properly seated. Check that the T-Connector ends are fully locked into the vehicle's wiring connectors on both driver and passenger sides. Ensure the white ground wire is securely fastened with the eyelet and screw. Verify that the black power wire is properly connected to the battery through the yellow fuse holder and that the fuse is installed. Test the installation with a test light or trailer. Reset the vehicle's electrical system by temporarily removing the ignition key. If the system still does not function, check that all connector surfaces are clean and free of dirt, and that no wires have been pinched or damaged during installation.
Dim or flickering lights indicate a poor electrical connection. Check that all connector surfaces are clean and free of dirt. Verify that the T-Connector ends are fully seated and locked into the vehicle's wiring connectors. Ensure the white ground wire is securely fastened to the vehicle frame with the eyelet and screw. Check that the black power wire is properly connected to the battery and that the fuse in the yellow fuse holder is not blown. If connections are secure and the fuse is good, the vehicle's battery may need charging or there may be a corroded connection at the battery terminals.
