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 kit includes a 12-volt sealed lead-acid battery, a tow charger (ABCD), a battery case with cover, a breakaway switch, and wiring. The kit does not include the 1/4" bolt, lock nut, or 2x 1/4" jam nuts required to secure the breakaway switch bracket to the trailer frame—these must be sourced separately. A UV-resistant zip tie is required to secure the battery box cover but is not listed as included.
The battery is a 12-volt sealed lead-acid unit with dimensions of 3.54" length × 2.76" width × 4.13" height. Service life is 4–5 years under normal standby operating conditions, or 200–1000 charge/discharge cycles depending on depth of discharge and charge rate.
The system is designed for trailers equipped with electric brakes that require a breakaway battery. The manual does not specify exclusions by trailer type, bed length, or cab style. The battery case must be mounted securely to the trailer frame, jack post, or other suitable location. Consult the breakaway switch installation instructions for complete operating details.
One 1/4" bolt with a lock nut, or two 1/4" jam nuts, are required to bolt the breakaway switch bracket to the trailer frame or battery case bracket. These fasteners are not included in the kit and must be sourced separately.
The manual specifies that all wire connections must be soldered (soldering equipment required). A wrench or socket is needed to tighten the 1/4" bolt securing the breakaway switch bracket. The manual does not list other specific tools, but standard installation tools for wiring and mounting are implied.
Yes. The manual explicitly states to disconnect the trailer from the tow vehicle before checking and installing the battery. This is a required safety step before wiring the system.
Yes. The manual states "Check condition of battery prior to installation and prior to each trip." This is a required pre-installation check to ensure the battery is in good condition before mounting and wiring.
Mount the battery case securely to the trailer frame, jack post, or other suitable location on the trailer. The breakaway switch cable should be oriented toward the tow vehicle. The switch location must be selected to ensure an unobstructed line of pull in the event of vehicle separation.
Use a UV-resistant zip tie to secure the cover to the battery box, passing it through one or both of the holes provided. This prevents accidental opening of the battery box.
The negative (−) terminal must attach to ground, and the positive (+) terminal must attach to the breakaway switch. Improper polarity will destroy the brake control. This is a critical safety requirement.
Attach the breakaway switch cable to the tow vehicle frame, ensuring the cable does not drag on the ground and no strain or restriction is placed on the cable. Do not hook the cable to the safety chain loop or hitch ball.
No. Do not over-tighten the bolt. The switch must be able to pivot freely. Tighten only enough to secure the bracket while allowing the switch to move.
The schematic shows red (+) for positive 12-volt connections, black (−) for ground/negative connections, blue for brake output connections, and white for additional connections. All connections must be properly insulated and soldered according to the wiring schematic provided in the manual.
Yes. The manual states "SAFETY ITEM: Solder all wire connections." This is a mandatory safety requirement for proper electrical integrity.
Yes. To charge the breakaway battery only when the vehicle is running, a battery isolator may be installed in the 12-volt supply line (red wire for tow charger). This prevents the tow vehicle's battery from being drained when the trailer is parked.
Disconnect the trailer plug before testing the breakaway unit. Failure to do so will result in severe damage to the electronic brake control.
Check your breakaway system periodically to ensure that wiring and connections are secure. A short or an open circuit can result in a no-brake condition. The manual recommends replacing breakaway devices every 3–5 years for optimal performance.
The maximum charge current must be limited to 1.2 amps or less. Charging at the proper rate is essential to avoid over or undercharge, which is the single worst enemy of lead-acid batteries.
Avoid exposing the battery to heat. Service life is shortened considerably at ambient temperatures above 30°C (86°F). Do not store the battery in a discharged state or at elevated ambient temperatures.
No. Do not attempt to disassemble the battery. Contact with sulfuric acid may cause harm.
Do not expose the battery case to organic solvents or adhesives. If exposure occurs, the battery may be damaged and should not be used.
Provide adequate air circulation when charging the battery. Do not charge the battery in any container besides the supplied battery box. Do not place batteries in close proximity to objects which can produce sparks or flames.
After six to nine months of storage, the battery should be recharged. This is necessary due to the characteristics of sealed lead-acid batteries.
Tekonsha charger 2024-07 (Heavy Duty Multi Stage/Maintenance Charger) is recommended for proper charging of the breakaway battery. This charger is designed to prevent over or undercharge.
Fasten the battery tightly and make provisions for shock absorption if exposure to shock or vibration is likely. This prevents damage from movement during towing.
Check the battery condition and recharge it using a Heavy Duty Multi Stage/Maintenance Charger. Tekonsha charger 2024-07 is recommended for proper charging. Excessive discharge may indicate a wiring problem or parasitic drain.
The system is designed for trailers with electric brakes. The battery case mounts to the trailer frame, jack post, or other suitable location. Consult the breakaway switch installation instructions for complete compatibility details.
You must source one 1/4" bolt with lock nut, or two 1/4" jam nuts, to secure the breakaway switch bracket. These are not included in the kit.
Yes. All wire connections must be soldered. This is a mandatory safety requirement for proper electrical integrity.
Maximum charge current is 1.2 amps or less. Exceeding this will damage the battery.
Disconnect the trailer plug before testing. Failure to do so will cause severe damage to the electronic brake control.
Service life is 4–5 years under normal standby conditions, or 200–1000 charge/discharge cycles depending on depth of discharge and charge rate. Breakaway devices should be replaced every 3–5 years for optimal performance.
