Description

The Tekonsha Brakeman IV digital trailer brake controller provides safety and connection when you need it most. As a time-based controller, the Brakeman IV is a great choice for basic, light-duty towing needs. This compact controller works by electronically connecting your vehicle and your trailer. When you hit the brakes in your tow vehicle, it generates an output signal that ramps up, or increases over a period of time, applying braking power to your trailer at a fixed rate. The Brakeman IV has up-front buttons so you can easily adjust power output, the sync – or aggressiveness with which the controller applies the brakes, and engage manual override to help you brake safely when an unexpected stop pops up. It also works with electric or electric over hydraulic braking systems, and features advanced internal circuit protection, real time comprehensive diagnostics, and short circuit protection. Because the Brakeman IV is a time-based controller, there’s no requirement that it be positioned in the direction of travel; it can be installed anywhere you like as long as it is within reach of the driver. Plus, the Plug & Play feature allows for quick and easy connection with your vehicle’s wiring. The Brakeman IV trailer brake controller works with1-4 axle trailers, comes with all the mounting hardware needed for installation, and is backed by a limited lifetime warranty.

  • Great controller
Size: Standard Pattern Name: Controller
This controller works great. Easy to install if you buy the dedicated adapter for your vehicle. Put it in my 2021 Ram 1500 and it was plug and play. Nice controller for this price. Note that this controller has a delay feature...may not work as well for very trailers.

  • Low profile
Size: Standard Pattern Name: Controller
Fits my f150 xlt 2015 perfectly. I just wish I mounted it a bit lower so you couldn't see the wire. But it works great and also very easy to install. Just remember before buying you need to buy a wire harness adapter for your vehicle.

  • Working perfectly
Size: Standard Pattern Name: Controller
Bought this unit in order to be able to utilize the electric brakes on the 16 ‘ lightweight trailer purchased to haul a couple of early British sport vehicles. My GMC Arcadia had the trailer package but you need to add a control in order to be able to utilize all the features of same. This control allows that easily by way of a simple connector that you connect between the controller and the factory trailer package connector that’s part of the trailer package. Super convenient and so simple to do. The control mount easily out of the way and allows complete control over the application of trailer breaks. ... show more
