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, this T-Connector is designed for the Nissan NV. It connects to the vehicle's taillight wiring harness at the rear of each taillight assembly.
The T-Connector is a trailer wiring adapter that taps into your Nissan NV's taillight wiring to provide trailer lighting signals. It connects to the existing taillight harness and routes power and ground to a 4-flat connector for trailer use.
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.
The kit includes: T-Connector harness with green and yellow wire ends, white ground wire with eyelet, black 12 ga. power wire, yellow fuse holder with 10 amp fuse, yellow butt connector, cable ties, mounting screw for ground eyelet, and a 4-flat connector for storage in the rear cargo area when not in use.
Yes. Disconnect the vehicle's negative (−) battery cable before connecting the power wire to the battery. Reconnect it after the fuse holder is installed and the 10 amp fuse is in place.
Open the rear door and locate the vehicle jack storage compartment on the passenger's side. Remove the panel and tire jack to access the harness area where the taillight wiring connections are located.
On the passenger side, insert the T-Connector end with the green wire between the vehicle wiring connectors and lock into place. Be careful not to damage the locking tabs and ensure connectors are fully inserted with locking tabs in place. Repeat on the driver's side with the T-Connector end containing the yellow wire.
After connecting the green wire end on the passenger side, temporarily remove the rear threshold plate and route the connector containing the green wire down the threshold to the driver side of the vehicle. This allows both the green and yellow wire ends to be accessible for connection.
Yes. You must drill a 3/32" hole on the driver's side near the connectors to secure the white ground wire with an eyelet using the provided screw. Verify what is behind any surface before drilling to avoid damage to the vehicle or personal injury. Do not drill into exposed surfaces.
Drill a 3/32" hole on the driver's side near the connectors. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into any exposed surfaces.
Locate a suitable grounding point on the driver's side near the connectors. Drill a 3/32" hole and secure the white wire with the eyelet using the screw provided. The white wire must be grounded for the T-Connector to function properly.
Locate the red 12 ga. power wire from the T-Connector box on the driver's side. Attach the black 12 ga. wire provided. Route the black wire through a grommet and along the exterior frame, or follow existing wiring along the thresholds into the engine compartment up to the battery. Disconnect the vehicle's negative battery cable. Remove the fuse from the yellow fuse holder, 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 provided.
The power connection uses 12 ga. (12 gauge) wire. The red 12 ga. wire comes from the T-Connector box, and a black 12 ga. wire is provided for connection to the vehicle battery.
Install a 10 amp fuse into the yellow fuse holder provided. This fuse protects the circuit and must be in place for the T-Connector to function properly.
Green wire: passenger-side taillight connection. Yellow wire: driver-side taillight connection. White wire: ground connection (secured with eyelet to a drilled hole). Red 12 ga. wire: power input from T-Connector box. Black 12 ga. wire: power output to vehicle battery positive terminal via fuse holder.
Route the black 12 ga. power wire through a grommet and along the exterior frame, or follow existing wiring along the thresholds into the engine compartment up to the battery. Avoid areas that may pinch or break the wire. Do not route the wire near hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
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 pinch, cut, or melt the wire.
Do not exceed the lower of the vehicle manufacturer rating or: maximum 2 stop/turn lights per side (4.2 amps) or maximum tail lights (7.5 amps). Overloading the circuit can cause fires.
Overloading the circuit can cause fires. The T-Connector is limited to a maximum of 2 stop/turn lights per side (4.2 amps) or maximum tail lights (7.5 amps), whichever is lower than the vehicle manufacturer's rating. Always verify your trailer's lighting requirements against these limits.
Mount the module so that the epoxy side is pointed towards the ground to prevent any water buildup. Improper mounting can allow water to accumulate and damage the module.
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-Connector to function properly.
Verify that all connections are complete and secure. Test the installation with a test light or by connecting a trailer and checking that all lights function correctly. Ensure the module is mounted with the epoxy side pointing toward the ground. Confirm that all wires are secured with cable ties and routed away from hot surfaces, pinch points, and the fuel tank. Reinstall the threshold, storage covers, floor covering, and other items removed during installation, being careful not to pinch or cut the wires.
Store the 4-flat connector in the rear cargo area when not in use.
Yes. Temporarily remove the rear threshold plate to route the connector containing the green wire down the threshold to the driver side of the vehicle. After routing, reinstall the threshold plate, being careful not to pinch or cut the wires.
Remove the jack storage compartment panel and tire jack to access the harness area. Temporarily remove the rear threshold plate to route the green wire connector. After installation, reinstall the threshold, storage covers, floor covering, and other items removed during installation, being careful not to pinch or cut the wires.
Verify that all connections are complete. Check that: (1) the green and yellow wire connectors are fully inserted into the taillight harness with locking tabs engaged, (2) the white ground wire is securely fastened to a suitable grounding point, (3) the black power wire is connected to the vehicle's positive battery terminal via the fuse holder, (4) the 10 amp fuse is installed in the fuse holder, and (5) the vehicle's 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.
Ensure the module is mounted so that the epoxy side is pointed towards the ground. If water is already present, remount the module with the correct orientation. Improper mounting allows water to buildup and can damage the module.
Check the following: (1) Verify all T-Connector wire connections to the taillight harness are fully inserted and locked. (2) Confirm the white ground wire is securely attached to a suitable grounding point. (3) Check that the 10 amp fuse is installed and not blown. (4) Ensure the black power wire is properly connected to the vehicle's positive battery terminal. (5) Verify the vehicle's negative battery cable is reconnected. (6) Reset the vehicle electrical system by temporarily removing the ignition key. (7) Test with a test light or trailer.
