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 2018-2020 Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118712 (Part #TK118712) Drilling is required for installation. Basic hand tools are typically all you need.
Yes, this T-Connector is designed for the Chrysler Pacifica. The installation instructions are specific to this vehicle model.
The T-Connector is a wiring module that integrates trailer lighting signals with your vehicle's taillight system. It allows you to connect a trailer's 4-flat connector to your Chrysler Pacifica's existing taillight wiring.
You will need: Trim Panel Remover, 10mm Socket & Ratchet or 10mm Wrench, 8mm Socket & Ratchet or 8mm Wrench, Torx T27 Socket & 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 package includes: double-sided tape for mounting the black box module, a yellow fuse holder with a 15 amp fuse, a yellow butt connector, a white eyelet and screw for the ground wire, cable ties for securing the harness, and the T-Connector harness with yellow and green wire ends and a 4-Flat connector.
Yes. The 4-Flat connector end must be mounted in an accessible location with a bracket or electrical box, which are not included with the T-Connector kit.
Yes. You must disconnect the vehicle's Negative (−) battery cable before connecting the power wire to the battery. The battery is reconnected in Step 10 after the fuse holder is installed.
Yes. You must remove both the driver and passenger side taillights using a Torx T27 Socket & Ratchet or Torx T27 Wrench. After removing the screws, carefully pull the taillights away from the vehicle without damaging the alignment pins.
Yes. You must 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.
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 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.
A 3/32" drill bit is required. The hole is drilled on the driver's side near the connectors to secure the white ground wire with an eyelet and screw.
The T-Connector uses a 15 amp fuse. This fuse is installed in the yellow fuse holder that connects the black 12 ga. power wire from the T-Connector box to the vehicle's Positive (+) battery cable.
The T-Connector harness has three main wire ends: yellow wires (driver's side taillight connection), green wires (passenger's side taillight connection), and a white wire (ground connection). The power circuit uses a black 12 ga. wire.
Route the yellow wire end up between the bumper and vehicle body into the driver's side taillight pocket. Route the green wire end to the passenger's side and the 4-Flat connector underneath the bumper, then up through the opening on the passenger side. Route the black 12 ga. power wire along the exterior frame or follow existing wiring along the thresholds into the engine compartment to the battery. Avoid hot pipes, heat shields, fuel tanks, and any areas that may pinch or break the wire. Secure the harness with cable ties provided.
Mount the black box module behind the rear bumper fascia on the driver's side using the double-sided tape provided. Ensure the trailer's wire harness has adequate length to reach this point. Mount the module in a protected area where it cannot be damaged by road debris or objects driven over. The epoxy side of the module must point toward the ground to prevent water buildup.
Do not exceed the lower of your vehicle manufacturer's rating or: maximum 2 stop/turn lights per side (4.2 amps total), and maximum tail lights (7.5 amps). Overloading the circuit can cause fires.
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. When mounting under the vehicle, ensure the unit is in a protected area and cannot be damaged by road debris. Avoid pinching, cutting, or melting wires during routing. Keep all connector surfaces clean and free of dirt. Read and follow all warnings and cautions printed on the tow vehicle's battery.
All connections must be complete for the T-Connector to function properly. Test and verify 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.
After reinstalling the taillight assemblies and other items removed during installation, carefully verify that no wires have been pinched or cut. Ensure all connections are complete and secure. Test the installation with a test light or trailer to confirm proper function.
Yes, the T-Connector (part 118712-037) is designed specifically for the Chrysler Pacifica.
You need: Trim Panel Remover, 10mm and 8mm sockets/wrenches, Torx T27 socket/wrench, 3/32" drill bit, 1/4" socket, wire crimpers and cutters, Philips screwdriver, and test-probe.
Yes, you must disconnect the vehicle's Negative (−) battery cable before connecting the power wire, and reconnect it after the fuse holder is installed.
Yes, you must drill a 3/32" hole on the driver's side to secure the white ground wire. Always verify what is behind the surface before drilling.
The T-Connector uses a 15 amp fuse installed in the yellow fuse holder provided.
Do not exceed: 2 stop/turn lights per side (4.2 amps) or tail lights (7.5 amps). Overloading can cause fires.
Verify that all connections are complete. Check that the yellow wire end is properly plugged between the mating plugs on both the driver's and passenger's side taillight sockets and vehicle wiring harness. Ensure the ground wire (white) is securely fastened with the eyelet and screw. Verify the 15 amp fuse is installed in the yellow fuse holder and that the fuse holder is properly connected to the black 12 ga. power wire using the yellow butt connector. For the initial test, reset the vehicle electrical system by temporarily removing the key from the ignition. Test with a test light or trailer to verify proper function.
The module is mounted with the epoxy side facing upward instead of toward the ground. The epoxy side must point toward the ground to prevent water buildup. Remount the module so that the epoxy side faces downward.
Secure the remainder of the T-Connector harness with the cable ties provided to prevent damage or rattling. Ensure the harness is routed away from any areas that would pinch, cut, or melt the wire, such as hot pipes, heat shields, and the fuel tank. Verify that the harness is not pinched or cut when reinstalling the taillight assemblies and other removed items.
