Most brake controllers stick out and take up knee room, but this one hides the main unit behind the dash. All you see is a small control knob—just 9/16" wide and less than 2" long—that handles everything. It looks like a factory switch and keeps your cab tidy. Turn it to adjust power or press it for manual override. The LED changes color to show braking strength or system status, so you always know what’s happening.
Uneven ground can make towing unpredictable. The off-road mode gives you direct control over your trailer brakes with preset power independent of your vehicle braking. Set it low for sand or mud so the trailer doesn’t dig in, or higher for steep descents to keep it from pushing forward. A quick double tap on the knob activates the mode, and the green LED confirms it’s ready.
Braking feels natural with proportional control that matches your trailer’s braking force to your tow vehicle’s deceleration. The internal 3-axis accelerometer senses movement in any direction, applying the right amount of brake power every time. It works with electric or electric-over-hydraulic systems on trailers with up to 3 axles (6 brake assemblies), keeping stops smooth and even while reducing wear on both sets of brakes.
Wiring a controller doesn’t have to mean cutting or splicing. The included adapter connects directly to a Tekonsha plug-in harness for a straightforward installation. Mount the compact 4" x 3-3/8" x 1-1/8" main unit anywhere within the reach of its 3' cable, then secure it with screws, tape, or zip ties. A universal mounting panel helps the knob blend in for a factory finish.
Designed for both 12-volt and 24-volt systems, the controller outputs 9V–32V and handles up to 25 amps continuous current at 12V DC maximum charging voltage. It meets UNECE R21 and FMVSS 201 safety standards, ensuring consistent operation under demanding conditions. A 2-year warranty backs its durability and performance wherever you tow.
