The Tekonsha Primus IQ electric trailer brake controller gives you dependable braking power in a compact design. As an industry staple for more than ten years, this proportional braking system provides a smooth braking response in any stopping situation. With its petite yet durable exterior, this trailer brake controller fits nicely under the dash, making it easily accessible from the driver’s seat without being in the way. While also compact, the brains of the Primus IQ are astute. This insightful brake controller has an easy-to-read LED display, self-diagnostic check to monitor your connection and trailer braking activity and is self-leveling when mounted within a 90-degree vertical range, so there’s no need to adjust the unit once it’s installed. It also features a power output knob to set your desired braking power, a boost option that lets you apply up quickly and easily to three levels of additional trailer braking power, especially when hauling heavier loads, and manual override. The Primus IQ was created to work with electric braking systems, works proportionally in reverse to make backing into tough spots a bit easier, and - like the Prodigy P3, Prodigy P2, and many other Tekonsha brake controllers – utilizes primary sensor technology to ensure the smoothest stop possible. When you’re done towing, the IQ’s snap-in dash mounting clip, Plug & Play port for two plug adapters, and removeable electrical connector allow the unit to be quickly stored. The Primus IQ is truly a complete trailer brake controller kit. It works with trailers with 1-3 axles, comes with all necessary mounting hardware, and is backed by a limited lifetime warranty.
