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 1994-1998 Jeep Grand Cherokee Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118349 (Part #TK118349) Drilling is required for installation. Basic hand tools are typically all you need.
The part number is 18349-037. This is a T-connector adapter with a black box module designed to integrate with vehicle tailgate wiring harnesses.
This unit is rated for 4 amps per circuit maximum. Do not exceed this rating when connecting accessories or trailers.
This adapter is designed to work with vehicles that have gray connection points on their wiring harness matching the T-connector ends. The adapter connects to the vehicle's existing tailgate electrical harness. Verify your vehicle has the matching gray connectors before purchasing. The manual does not specify which vehicle makes and models are compatible.
You will need a drill with a 3/32" bit to create the grounding hole. A test light or trailer is recommended to test the installation after completion. The manual does not specify whether a screwdriver, wire strippers, or other hand tools are required, though these are typically needed for electrical connections.
The kit includes: two T-connector adapters (one with yellow wire, one with green wire), a black box module, a 12 gauge black wire, a fuse holder with a 10 amp fuse, a ring terminal, yellow butt connectors, an eyelet and screw for grounding, cable ties, and foam tape for mounting the black box.
Yes. You must disconnect the vehicle's negative (−) battery cable before beginning installation. Reconnect it only after the fuse has been installed in step 11, after all wiring is complete.
Yes. The manual requires you to open the rear tailgate and remove the spare tire to access the electrical access panel on the left (driver's) side. The spare tire must be reinstalled at the end of the installation.
1. Locate the vehicle's gray wiring harness connectors matching the T-connector ends. 2. Carefully separate the gray connectors without breaking the locking tabs. 3. Insert the T-connector (yellow wire first on the driver's side) between the separated halves. 4. Lock the connectors into place, ensuring they are fully inserted with locking tabs engaged. 5. Repeat on the passenger side using the T-connector with the green wire, which is located behind the trim panel.
Beginning from the front of the vehicle, route the 12 gauge wire rearward along the frame rail, avoiding hot pipes, heat shields, the fuel tank, and any pinch points that could damage the wire. Continue to the rear driver's side and locate the small access hole under the body. Route the wire up through this hole to the black box attached to the T-connector adapter. Secure all loose wires with the cable ties provided.
1. Disconnect the vehicle's negative battery cable. 2. Remove the fuse from the supplied fuse holder. 3. Using the ring terminal provided, attach one end of the fuse holder to the vehicle's positive (+) battery cable. 4. Connect the other end of the fuse holder to the black 12 gauge wire included with the T-connector using the supplied yellow butt connector. 5. Route the 12 gauge wire to the rear and attach it to the wire on the black box labeled 'Battery +' using the butt connector provided.
Yes. You must drill a 3/32" hole near the black box to secure the white grounding wire using the eyelet and screw provided. Do not drill into any exposed surfaces such as the floor or cabin.
The grounding hole must be 3/32" in diameter. Drill this hole near the black box to secure the white grounding wire using the eyelet and screw provided.
The fuse rating is 10 amps. Install the 10 amp fuse into the fuse holder after all wiring is complete and before testing the installation.
The battery power wire is 12 gauge (12 ga.). This wire is included with the T-connector kit and connects from the fuse holder to the black box module.
The T-connector adapter includes two units: one with a yellow wire (installed on the driver's side) and one with a green wire (installed on the passenger side). These connect to the vehicle's tailgate wiring harness. The black 12 gauge wire carries battery power, and the white wire is the ground connection.
Yellow butt connectors are supplied with the kit. These are used to connect the fuse holder to the black 12 gauge wire and to connect the black wire to the 'Battery +' terminal on the black box.
When routing the 12 gauge black wire from the front of the vehicle to the rear, avoid hot pipes, heat shields, the fuel tank, and any other points that may pinch or break the wire. Route the wire along the frame rail to protect it from damage. Do not drill into exposed surfaces such as the floor or cabin when installing the grounding connection.
When separating and connecting the gray harness connectors, be careful not to break the locking tabs. Ensure that the connectors are fully inserted with locking tabs in place before proceeding. Improper connection could result in poor electrical contact or damage to the connectors.
After reconnecting the negative battery cable and installing the 10 amp fuse, test the installation using a test light or trailer. This will verify that power is being supplied correctly through the adapter to the connected device.
Clean a flat area near the black box using a mixture of rubbing alcohol and water. Mount the black box to the clean area using the foam tape provided. Ensure the surface is dry and free of debris before applying the tape.
Secure all loose wires using the cable ties provided with the kit. This prevents wires from moving, rubbing against sharp edges, or becoming damaged during vehicle operation.
Yes. After testing the installation and securing all wires, reattach the access panels, trim panels, threshold, cargo net brackets, and spare tire to their original positions.
This adapter works with vehicles that have gray connection points on their tailgate wiring harness matching the T-connector ends. Check your vehicle's harness before purchasing.
You need a drill with a 3/32" bit for the grounding hole. A test light or trailer is recommended to verify the installation works correctly.
