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 TK22127 (Part #TK22127) fits 2021-2024 Ford Bronco models. The 2024 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 TK22127 (Part #TK22127) fits the following vehicles: 2021-2024 Ford Bronco. Always verify your specific year, make, and model before ordering.
The Tekonsha Tow Harness, 7-Way Complete Kit TK22127 (Part #TK22127) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The kit includes: 7-way socket, 7-way connector with wire lock, T-One connectors (2), power module (Modulite), fuse holders (2), fuses (25 AMP and 30 AMP), ring terminals (2), yellow butt connectors (3), cable ties (24 at 8.5" and 1 at 14.5"), and double-sided tape. The brake control module and 7-way mounting bracket are sold separately.
The kit is designed for Ford Bronco with LED tail lights. The manual does not specify which model years or trim levels are compatible. Contact Tekonsha technical assistance at 800-632-3290 or visit www.tekonsha.com to confirm fitment for your specific vehicle.
Required tools are: Phillips head #2 screwdriver, wire cutters, wire strippers/wire crimpers, tester or volt meter, 10 mm socket, trim panel puller, ratchet, and heat gun. The heat gun is essential for applying heat to butt connectors until the tubing recovers and adhesive flows.
Yes. The first step is to disconnect and isolate the vehicle's negative battery terminal. Reconnect it only after all wiring is complete and before testing the installation.
The manual states that if you are still having troubles after following the troubleshooting guide, you should contact a Tekonsha-approved installer for professional installation. You can find one by entering your zip code at www.tekonsha.com under 'Where to buy'.
Yes. You must drill a 3/32" hole to secure the white ground wire to the vehicle's frame or crossmember using the supplied eyelet and screw. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into the vehicle floor or bed.
You must remove the taillight protective covers to access the taillight connectors. Open the rear door, use a Phillips screwdriver to unscrew 4 clips on each cover, remove the cover with a panel puller, and remove 2 10MM bolts using a 10MM socket. After installation, replace the covers and secure them with the clips and bolts.
The 7-way harness contains: Green (tail lights), Black (+12V battery), Brown (right/stop light), Red (left/stop light), White (ground), Blue (trailer brakes), and Yellow (backup lights). The body harness also includes Black/Blue/Red wires that connect to the power module.
Insert the T-One connector end (yellow wire for driver's side, green wire for passenger's side) between the vehicle's existing taillight wiring connectors and lock into place. Ensure connectors are fully inserted with locking tabs in place. All connector surfaces must be clean and free of dirt before connecting.
Mount the T-Connector black box (power module) on a flat surface located above and behind the taillight using the supplied double-sided tape. The module must be mounted with the epoxy side pointed towards the ground to prevent water buildup.
The 25 AMP fuse protects the tow harness power module. The 30 AMP fuse protects the 7-way harness power supply. Both fuses are essential for circuit protection and must be fully inserted into their respective fuse holders.
Route the blue wire from the body harness through a grommet in the firewall. Connect the blue wire from the body harness to the blue wire from the brake control harness using the supplied yellow butt connector. The brake control module is sold separately and is compatible with Tekonsha models 90195, 90885, or 90160.
Use a heat gun or other heat source to apply heat directly to the butt connectors, working from the center out to the edges, until the tubing recovers and the adhesive flows. Allow the connectors to cool before inspecting the splice and checking integrity.
Do not exceed: maximum 2 stop/turn/backup lights per side (4.2 amps total), maximum tail lights (7.5 amps), and maximum 7-way 12-volt positive (30 amps). Overloading the circuit can cause fires.
Wear safety glasses during installation. When routing wires through grommets or along the exterior of the vehicle, avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. Secure the harness with cable ties provided, being careful to avoid areas that would pinch, cut, or melt the wire. Some grommets may need to be altered; seal altered grommets with silicone.
After reconnecting the vehicle's negative battery cable, test and verify the installation with a test light or by connecting an actual trailer. This confirms that all lights and functions are working correctly.
Ensure all harness is secured with cable ties to prevent damage or rattling. Verify that butt connectors are properly heated and cooled. Replace all protective covers, grommets, and components that were removed. Reconnect the negative battery cable. Test all functions with a test light or trailer. Verify that the power module is mounted with epoxy side down and that all connectors are fully inserted and locked.

The brake control module is sold separately. Compatible models are Tekonsha 90195, 90885, or 90160. The 7-way mounting bracket is also not included.
Yes. You must drill one 3/32" hole to secure the white ground wire to the vehicle's frame or crossmember. Verify what is behind the surface before drilling.
Phillips #2 screwdriver, wire cutters, wire strippers/crimpers, tester or volt meter, 10mm socket, trim panel puller, ratchet, and heat gun.
Yes. Disconnect and isolate the negative battery terminal before starting installation. Reconnect only after all wiring is complete.
Max 2 stop/turn/backup lights per side (4.2 amps), max tail lights (7.5 amps), max 7-way 12V+ (30 amps). Exceeding these limits can cause fires.
First, ensure the T-One T-Connector ends are fully inserted and locked in place. If the problem persists, check the chassis grounds and ensure ring terminals are in full contact with the vehicle's bare chassis metal. Remove the tow harness power module 25 AMP fuse for 10 seconds and repeat the test. If still not working, contact a Tekonsha-approved installer.
1. Verify the 25 AMP fuse is fully inserted into the fuse holder with no breaks. 2. Ensure the fuse holder is connected properly to the positive post of the battery. 3. Verify the module is connected to B+ (positive). 4. Use a tester or volt meter to check for voltage on either side of the yellow butt connector near the module. 5. Remove the 25 AMP fuse for 10 seconds and repeat the test. If the installation may have activated circuit protection, start the vehicle and turn off all functions (tail lights, brake, turns), then remove the 25 AMP fuse for 10 seconds and repeat the test.
