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 Tow Harness, 7-Way Complete Kit TK22122 (Part #TK22122) fits 2013-2023 Hyundai Santa Fe models. The 2023 model year is the last year covered by this part number. For newer models, check for an updated version.
The Tekonsha Tow Harness, 7-Way Complete Kit TK22122 (Part #TK22122) Drilling is required for installation. Basic hand tools are typically all you need.
This kit is designed for Kia Sorento and Hyundai Veracruz only. Installation procedures differ between these two models, particularly for accessing the vehicle's tow-plug harness and routing wires. Verify your vehicle model before purchasing.
Required tools: wire strippers/crimpers, wire cutters, 10mm socket, ratchet, trim panel puller, tester or volt meter, and heat gun. The kit includes 24 cable ties (8.5"), 1 cable tie (14.5"), 1 wire tap, fuses (1×25 AMP, 2×30 AMP), 3 ring terminals, 2 fuse holders, 4 yellow butt connectors, and double-sided tape.
Yes. Disconnect and isolate the vehicle's negative battery terminal before beginning installation. Reconnect it only after all wiring is complete and secured.
Do not exceed: Max. stop/turn/backup light 2 per side (4.2 amps); Max. tail lights (7.5 amps); Max. 7-Way 12 Volt + (30 amps). Overloading can cause fires.
No drilling of the vehicle frame is required. However, for the Hyundai Veracruz, you must create a small hole in the existing firewall grommet to pass the brake control harness wires through. Some grommets may need to be altered to allow wires to pass; seal altered grommets with silicone.
The kit includes one 25 AMP fuse for the power module and two 30 AMP fuses for the 7-Way connector and brake control connections. The 25 AMP fuse protects the main power module; the 30 AMP fuses protect the 7-Way and brake control circuits.
Wear safety glasses throughout installation. Route all wires carefully to avoid hot pipes, heat shields, fuel tank, or points that may pinch or break the wire. Do not exceed circuit amperage limits (max. 30 amps on 7-Way +12V) to prevent fires. Ensure all connections are fully inserted and locked before testing.
After reconnecting the negative battery cable, test and verify the installation with a test light or trailer. For initial testing, reset the vehicle electrical system by temporarily removing the key from the ignition, then reinsert it and test all functions. If the 7-Way is not functioning, remove the 25 AMP fuse for 10 seconds and repeat the test.
The manual does not address compatibility with roof racks or cargo carriers. Contact Tekonsha technical support at 800-632-3290 or consult an approved installer to confirm fitment with aftermarket roof equipment.
The kit is designed to connect to the vehicle's factory tow-plug harness, which is located underneath the vehicle on the passenger side, on top of the frame rail near the rear tire. If your vehicle has a factory tow package with a pre-installed tow-plug, the T-Connector harness will plug directly into it. Verify that your vehicle has this factory tow-plug before purchasing.
The kit includes: 24 cable ties (8.5"), 1 cable tie (14.5"), 1 wire tap, 1 fuse (25 AMP), 2 fuses (30 AMP), 3 ring terminals, 2 fuse holders, 4 yellow butt connectors, T-One T-Connector harness with Modulite module, 7-Way harness with connector and socket, body harness with red/black/blue wires, brake control harness with white/blue/black wires, convoluted tubing, double-sided tape, and protective caps for the tow-plug. The 7-Way bracket and 4-flat end bracket are not included.
No. The brake control harness is included, but the brake control module is sold separately. The harness is designed to work with Tekonsha brake controls such as models 90195, 90885, or 90160. Visit www.tekonsha.com for details on compatible brake controls and where to purchase.
On a Kia Sorento, lower the spare tire to gain access to the vehicle wiring. The factory tow-plug harness is located underneath the vehicle on the passenger side, on top of the frame rail near the rear tire. On some Sorento models, the vehicle wiring harness is located behind a protective cover on the driver's side frame rail; remove the plastic trim fasteners to access it.
On a Hyundai Veracruz, find the access hole inside the bumper support channel, above the passenger side exhaust, and route the T-Connector harness plugs through this hole. The factory tow-plug harness is located underneath the vehicle on the passenger side frame, near the rear tire. Route the 16 gauge blue wire through the grommet into the interior area, behind side cargo trim panels, and up above the head liner.
Locate the vehicle's tow-plug harness underneath the vehicle on the passenger side, on top of the frame rail near the rear tire. Remove the protective cap carefully without breaking the locking tabs. Ensure all connector surfaces are clean and free of dirt. Insert the T-Connector harness into the vehicle's tow-plug harness and lock into place. Verify that connectors are fully inserted with locking tabs in place. All connections must be complete for the T-Connector to function properly.
Mount the T-Connector black box using the double-sided tape provided onto the bottom of the bumper support channel. Secure all loose wires with cable ties to prevent damage or rattling.
Route the 16 gauge blue wire through the grommet into the interior area, behind side cargo trim panels, and up above the head liner. Locate the group of wires going through the grommet into the cargo door. Using a test light or volt meter, locate the backup/reverse wire in the rear cargo door electrical harness. Connect using the supplied wire tap or best suited alternative. Note: The backup/reverse wire can also be located in the vehicle taillights; remove the taillight or locate the harness behind the trim panel near the taillight area.
The body harness contains red, black, and blue wires. The black wire connects to the vehicle's positive battery post using a 30 AMP fuse holder, butt connector, and ring terminal. The blue wire connects to the trailer brake output (if using a brake control). The red wire connects to the cold side input from the brake control. Route all wires from inside the vehicle on the driver's side through the engine compartment, following existing wiring along the thresholds.
The brake control harness contains white, blue, and black wires. The white wire connects to the vehicle's existing chassis ground point using a ring terminal. The black wire connects to the vehicle's positive battery post using a 30 AMP fuse holder, butt connector, and ring terminal. The blue wire (electric brake output) connects to the body harness blue wire using a butt connector. The red wire (cold side input) connects to the body harness red wire using a butt connector. Route these wires through an existing firewall grommet into the engine compartment.
The 7-Way harness contains seven wires with the following functions: Green (tail lights), Brown (right/stop), Red (left/stop), White (ground), Blue (trailer brakes), Yellow (backup), and Black (+12V battery). Route the complete 7-Way harness behind the rear bumper fascia and over the bumper support bracket toward the mounting location. Use the wire insertion detail provided to pin the 7-Way connector correctly.
Route the 7-Way harness containing the 7 wires behind the rear bumper fascia and over the bumper support bracket toward the mounting location. Determine a suitable mounting location for the 7-Way connector and socket. The bracket is not included, so you will need to provide your own mounting solution. Connect the 7-Way connector to the 7-Way socket and secure it in place.
After inserting the yellow butt connectors onto the wire ends, apply heat directly to the butt connectors using a heat gun or other heat source, working from the center out to the edges, until the tubing recovers and the adhesive flows. Allow the connectors to cool completely before inspecting the splice and checking integrity. Do not use the connectors until they are fully cooled.
Secure all loose wires with the cable ties provided (24 ties of 8.5" and 1 tie of 14.5") to prevent damage or rattling. Be careful to avoid any areas that would pinch, cut, or melt the wire. Use the convoluted tubing provided to cover the blue/black/red wires (and partially the white wire) from the grommet to the fuse holder for additional protection.
Yes, for the brake control harness on Hyundai Veracruz. Route the brake control harness white/blue/black wires through an existing grommet on the firewall by creating a small hole in the grommet to pass the wires through. After installation, seal any altered grommets with silicone. Some grommets may also need to be altered to allow the 16 gauge blue wire to pass through; seal these with silicone as well.
After removing the protective caps from the vehicle's tow-plug harness, return them to the customer. Keep them in a safe place in case the tow-plug needs to be disconnected in the future.
Use the ring terminals provided to connect the body harness black wire and brake control harness black and white wires to the battery and chassis ground. For the battery connection, use a 30 AMP fuse holder with a butt connector and ring terminal. For the chassis ground connection, use a ring terminal and ensure it is in full contact with the vehicle's bare metal chassis. The manual does not specify torque values for these connections; consult the vehicle's service manual or a professional installer for proper torque specifications.
Route all wires carefully to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. This applies to the body harness, brake control harness, T-Connector harness, and 7-Way harness. Use cable ties to secure wires and prevent them from moving into dangerous areas. Avoid routing wires near moving parts or sharp edges.
After reconnecting the negative battery cable, verify that all connections are complete and secure. Test and verify the installation with a test light or trailer. For initial testing, reset the vehicle electrical system by temporarily removing the key from the ignition. Ensure all wires are properly secured with cable ties and that no wires are pinched or damaged. Verify that the T-Connector black box is securely mounted and that all protective coverings and grommets have been replaced.
The manual does not specify ongoing maintenance requirements. However, periodically inspect all connections, cable ties, and wires to ensure they remain secure and undamaged. If any wires become loose or damaged, resecure or repair them immediately. If you notice any electrical issues, refer to the troubleshooting guide or contact a Tekonsha approved installer.
The approximate installation time is 120 minutes. This assumes you have the required tools and are familiar with vehicle electrical systems. Actual time may vary depending on your experience level and vehicle condition.

First, ensure that the T-One T-Connector ends are fully inserted and locked in place. Remove the 25 AMP fuse from the power module for 10 seconds and repeat the test. Next, check the chassis grounds and ensure that the ring terminals are in full contact with the vehicle's bare metal chassis. Remove the 25 AMP fuse for 10 seconds and repeat the test. If the problem persists, contact a Tekonsha approved installer for professional assistance.
The installation may have activated circuit protection. Start the vehicle and turn all functions off: tail lights (head lights), brake, and turns. Remove the 25 AMP fuse from the power module for 10 seconds and repeat the test. Ensure the 25 AMP fuse is fully inserted into the fuse holder and has no breaks. Verify that the fuse holder is connected properly to the positive post of the battery. Using a tester or volt meter, check for voltage on either side of the yellow butt connector near the module. If voltage is present on one side but not the other, the butt connector may not be properly heated or seated. Remove the 25 AMP fuse for 10 seconds and repeat the test.
Ensure that you applied heat directly to the butt connectors using a heat gun or other heat source, working from the center out to the edges, until the tubing recovered and the adhesive flowed. Allow the connectors to cool completely before testing. If the connectors are still not holding, the adhesive may not have fully activated. Reapply heat and allow to cool again. If the problem persists, replace the butt connector with a new one from the kit or a compatible alternative.
