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 2019-2023 Jeep Cherokee Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118779 (Part #TK118779) Drilling is required for installation. Basic hand tools are typically all you need.
Yes, this T-Connector is designed for the Jeep Cherokee. However, the manual does not specify which model years or body styles (2-door vs. 4-door) are compatible. Contact the manufacturer or your installer to confirm fitment for your specific Cherokee model year.
The T-Connector is a trailer wiring harness that integrates with your Jeep Cherokee's taillight system to provide electrical connections for towing a trailer. It uses a 4-flat connector to deliver power and ground signals from the vehicle's taillights to the trailer.
You will need: 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, test probe, and Torx 30 driver.
The kit includes: double-sided tape for mounting the black box module, yellow wires and green wires for taillight connections, white ground wire with eyelet and screw, black 12 ga. power wire, yellow fuse holder with 15 amp fuse, yellow butt connector, and cable ties for securing the harness.
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, after routing the black 12 ga. power wire to the engine compartment. Reconnect the negative cable in step 11 after the fuse is installed.
Open the rear tailgate. On both the driver and passenger sides, remove two Torx-30 screws using a Torx 30 driver. Carefully pull each taillight away from the vehicle, being careful not to damage the alignment pins. The taillight wiring harness connector will then be accessible.
Mount the black box underneath the vehicle behind the rear bumper fascia on the driver's side, using the double-sided tape provided. The module must be in a protected area where it cannot be damaged by road debris or objects driven over. Mount it with the epoxy side pointed toward the ground to prevent water buildup.
On the driver's side, route the T-Connector end with yellow wires up between the bumper and vehicle body into the taillight pocket, then plug it between the mating plugs on the driver's side taillight socket and vehicle wiring harness. On the passenger's side, route the green wire end under the bumper and up through the opening, then plug it between the mating plugs on the passenger's side taillight socket and vehicle wiring harness.
Route the 4-flat connector underneath and to the center of the vehicle. Mount the 4-flat end in an accessible location using a bracket or electrical box (not included with the kit).
Yes. You must drill a 3/32" hole to secure the white ground wire. Locate a suitable grounding point near the connector on the vehicle's frame or crossmember (do not drill into the vehicle floor or bed). Clean dirt and rustproofing from the area, drill the hole, and secure the white wire using the eyelet and screw provided.
Drill a 3/32" hole for the white ground wire eyelet.
No. Do not drill into the vehicle floor or bed. Locate the ground point on the vehicle's frame or crossmember instead. Before drilling any surface, verify what is behind it to avoid damage to the vehicle and personal injury.
Route the black 12 ga. power wire from the T-Connector box along the exterior frame or follow existing wiring along the thresholds into the engine compartment up to the battery, avoiding areas that may pinch or break the wire. Disconnect 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, and secure it 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.
Install a 15 amp fuse into the yellow fuse holder after reconnecting the vehicle's negative (−) battery cable.
The T-Connector uses yellow wires for the driver's side taillight connection, green wires for the passenger's side taillight connection, white wire for ground, and black 12 ga. wire for power from the battery.
Avoid any hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. Route the harness carefully through grommets and along the exterior of the vehicle. Secure the remainder of the harness with the cable ties provided to prevent damage, rattling, and to avoid areas that would pinch, cut, or melt the wire.
Verify what is behind any surface prior to drilling to avoid damage to the vehicle and personal injury. Do not drill into any exposed surfaces.
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. Overloading circuits can cause fires.
All connections must be complete for the T-Connector to function properly. Test and verify the installation with a test light or trailer once installed. For the initial test, reset the vehicle's electrical system by temporarily removing the key from the ignition.
Yes. When you separate the vehicle's taillight wiring harness connector, ensure all connector surfaces are clean and free of dirt before plugging in the T-Connector ends.
The T-Connector (part 118779-037) is designed for the Jeep Cherokee. Confirm your specific model year with the manufacturer or installer.

Verify that all connections are complete. Test and verify the installation with a test light or trailer. If the system still does not function, reset the vehicle's electrical system by temporarily removing the key from the ignition. Ensure the 15 amp fuse is installed in the yellow fuse holder and that the negative (−) battery cable is fully reconnected.
The module may not be mounted correctly. The epoxy side of the module must be pointed toward the ground to prevent water buildup. Remount the module with the correct orientation.
