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 Tekonsha T-One T-Connector Harness, 4-Way Flat, w/Circuit Protected ModuLite HD Module TK118723 (Part #TK118723) Drilling is required for installation. Basic hand tools are typically all you need.
Yes, the T-Connector is designed for Chrysler Pacifica LX and Chrysler Pacifica Touring models. The installation instructions are specific to these vehicles.
The T-Connector is a wiring module that integrates trailer lighting into your vehicle's electrical system. It connects between the vehicle's taillight wiring harness and provides a 4-flat connector outlet for trailer hookup. The module mounts under the vehicle behind the rear bumper and requires connection to the vehicle's battery and ground.
Required tools are: Trim panel remover, 10mm socket and ratchet (or 10mm wrench), 8mm socket and ratchet (or 8mm wrench), Torx T27 socket and ratchet (or Torx T27 wrench), drill with 3/32" drill bit, 1/4" socket, wire crimpers, wire cutters, Philips head screwdriver, and test probe.
The kit includes: the T-Connector black box module, double-sided tape for mounting, yellow fuse holder with 15 amp fuse, yellow butt connector, white eyelet and screw for ground wire, black 12 gauge power wire, cable ties for securing the harness, and the T-Connector harness with yellow and green wire ends and 4-flat connector.
No. The bracket or electrical box for mounting the 4-flat connector end is not included and must be obtained separately. The instructions note that the 4-flat end should be mounted in an accessible location with a bracket or electrical box.
Yes. The vehicle's negative (-) battery cable must be disconnected before connecting the power wire to the positive (+) battery terminal. The negative cable is reconnected after the fuse holder is installed.
Yes. Both driver and passenger side taillight assemblies must be removed to access the taillight sockets and disconnect the vehicle wiring harness. Use a Torx T27 socket and ratchet (or wrench) to remove the fasteners. Be careful not to damage the alignment pins when pulling the taillights away from the vehicle.
Yes. Partially remove the underbody trim panel by removing 8mm and 10mm bolts to access the mounting area behind the rear bumper fascia on the driver's side. This is where the T-Connector black box module is mounted.
Yes. A 3/32" hole must be drilled on the driver's side near the taillight connectors to secure the white ground wire with an eyelet and screw. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into any exposed surfaces.
The T-Connector uses a 15 amp fuse. The fuse is installed in the yellow fuse holder that connects the black 12 gauge power wire from the T-Connector module to the vehicle's positive (+) battery terminal.
The T-Connector has three main wire ends: yellow wires connect to the driver's side taillight socket, green wires connect to the passenger's side taillight socket, white wire is the ground connection (secured with eyelet to the vehicle frame), and black 12 gauge wire is the power connection to the vehicle's positive battery terminal.
The T-Connector is powered by a black 12 gauge wire that connects to the vehicle's positive (+) battery terminal through a 15 amp fuse holder. The negative battery cable must be disconnected before making this connection. The fuse holder is connected to the black power wire using a yellow butt connector.
The T-Connector is grounded using a white wire with an eyelet. 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. Do not drill into any exposed surfaces.
The T-Connector black box module should be mounted behind the rear bumper fascia on the driver's side, underneath the vehicle. Use the double-sided tape provided. The module must be mounted in a protected area where it cannot be damaged by road debris or objects driven over. The epoxy side of the module must face the ground to prevent water buildup.
Route the black power wire along the exterior frame or follow existing wiring along the thresholds into the engine compartment, avoiding areas that may pinch or break the wire. Route the green wire to the passenger's side under the bumper, avoiding hot pipes, heat shields, fuel tank, and any points that may pinch or break the wire. Secure all wires with the cable ties provided to prevent damage, rattling, and to avoid areas that would pinch, cut, or melt the wire.
Always wear safety glasses during installation. Read and follow all warnings on the vehicle's battery before working with electrical connections. Verify what is behind any surface before drilling. Do not drill into exposed surfaces. Ensure the T-Connector module is mounted in a protected area away from road debris. Do not exceed the vehicle's towing manufacturer 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 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.
After installation, verify that all connections are complete and secure. Ensure the T-Connector module is properly mounted with the epoxy side facing the ground. Check that all wires are secured with cable ties and routed away from hot surfaces, pinch points, and moving parts. Reinstall all taillight assemblies and underbody trim panels carefully without pinching or cutting wires. Test the system with a test light or trailer before towing.
The 4-flat connector is the trailer hookup outlet. It is located at the end of the T-Connector harness with the green wire. This connector should be mounted in an accessible location using a bracket or electrical box (not included) so that a trailer can be easily connected and disconnected.
Yes, the T-Connector (118723-037) is designed for Chrysler Pacifica LX and Touring models.
You need: Torx T27 socket/wrench, 10mm and 8mm sockets/wrenches, trim panel remover, 3/32" drill bit, wire crimpers, wire cutters, Philips screwdriver, and test probe.
Yes, disconnect the negative battery cable before connecting the power wire to the positive terminal. Reconnect it after the fuse holder is installed.
