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 2218 is a 12-volt sealed lead-acid battery system designed to power electric trailer brakes via a breakaway switch. It includes a tow charger (ABCD) that charges the battery when the trailer is connected to the tow vehicle, and a breakaway switch that activates the trailer brakes if the trailer separates from the tow vehicle.
Under normal operating conditions, the battery provides 4–5 years of service life in standby applications, or 200–1000 charge/discharge cycles depending on depth of discharge and rate of charge.
Length = 3.54", Width = 2.76", Height = 4.13". The terminals are fasten tab type, 0.187" × 0.032".
One 1/4" bolt and lock nut, or two 1/4" jam nuts. These fasteners are not included in the kit and must be supplied separately.
Yes. A UV-resistant zip tie must be used to secure the cover to the battery box using one or both of the holes provided. This prevents accidental opening of the battery box.
Yes. The trailer must be disconnected from the tow vehicle before installing the battery and charger into the battery case. This is a required safety step before wiring the system.
Mount the battery case securely to the frame, jack post, or other suitable location on the trailer. The breakaway switch cable should be oriented toward the tow vehicle. Ensure the switch location is selected to provide an unobstructed line of pull in the event of vehicle separation.
Feed the wires out the back of the battery case, then close the top. Wire the system per the schematic diagram provided, and properly insulate all connections.
The negative (−) terminal must attach to ground, and the positive (+) terminal must attach to the breakaway switch. Improper installation of polarity will destroy the brake control.
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 it. 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 to function correctly.
Yes. All wire connections must be soldered as a safety requirement. This ensures secure electrical connections and prevents corrosion.
The maximum charge current must be limited to 1.2 amps or less. Exceeding this rate can damage the battery.
Tekonsha charger model 2024-07 is recommended for proper charging of the breakaway battery. It is a heavy-duty multi-stage/maintenance charger suitable for the 12-volt sealed lead-acid battery.
Check the condition of the battery prior to each trip. This includes verifying that the battery is charged, connections are secure, and there are no signs of damage or corrosion.
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, which is a safety hazard.
For optimal performance, it is recommended that breakaway devices be replaced every 3–5 years.
Avoid over or undercharge, which is the single worst enemy of lead-acid batteries. Do not store the battery in a discharged state or at elevated ambient temperatures. Avoid exposing the battery to heat; service life is shortened considerably at ambient temperatures above 30°C (86°F). After six to nine months of storage, the battery should be recharged.
Charge the battery at the proper rate with current limited to 1.2 amps or less. Provide adequate air circulation when charging. Do not charge the battery in any container besides the supplied battery box. Do not place batteries in close proximity to objects that can produce sparks or flames.
Check the battery and recharge it using a heavy-duty multi-stage/maintenance charger. Tekonsha charger 2024-07 is recommended for proper charging.
No. Do not expose the battery case to organic solvents or adhesives, as these can damage the case.
Do not throw batteries into fire. Batteries disposed of in fire may rupture or explode, creating a serious safety hazard.
Do not attempt to disassemble the battery. Contact with sulfuric acid inside the battery may cause harm.
Fasten the battery tightly and make provisions for shock absorption if exposure to shock or vibration is likely. This protects the battery from damage during transport.
A battery isolator is an optional device that can be installed in the 12-volt supply line (RED wire for tow charger) to charge the breakaway battery only when the tow vehicle is running. This prevents the tow vehicle's battery from being drained when the trailer is connected but the vehicle is off.
The 2218 is designed for trailers with electric brakes. Mount the battery case securely to the frame, jack post, or other suitable location. Verify your trailer has electric brakes before installation.
You must supply one 1/4" bolt and lock nut, or two 1/4" jam nuts, to secure the breakaway switch bracket. A UV-resistant zip tie is also required to secure the battery box cover.
Yes. Solder all wire connections as a safety requirement. This ensures secure electrical connections and prevents corrosion.
Maximum charge current must be limited to 1.2 amps or less. Use the recommended Tekonsha 2024-07 charger for proper charging.
Check the condition of the battery before each trip. Verify it is charged, connections are secure, and there are no signs of damage.
Severe damage to the electronic brake control will result. Always disconnect the trailer plug before testing the breakaway unit.
After six to nine months of storage, the battery should be recharged. Do not store the battery in a discharged state or at temperatures above 30°C (86°F).
A short circuit or an open circuit in the wiring or connections can result in a no-brake condition. Check your breakaway system periodically to ensure that wiring and connections are secure. Verify all solder joints are intact and no wires are damaged or corroded.
Excessive discharging can result from overcharging, undercharging, storage in a discharged state, exposure to heat above 30°C (86°F), or a faulty charger. Check the battery condition and recharge using a heavy-duty multi-stage/maintenance charger such as Tekonsha 2024-07.
Improper installation of polarity (negative terminal not grounded, positive terminal not connected to breakaway switch) will destroy the brake control. Verify correct polarity before powering the system: negative (−) to ground, positive (+) to breakaway switch.
