Tekonsha Primus IQ

Tekonsha Primus IQ is a vehicle-mounted electric trailer brake controller engineered for precise, confident towing. Designed to translate your braking input into proportional trailer brake force, this unit keeps your load steady and your stops smooth—even on challenging hills and winding roads.

Built to endure demanding use, Primus IQ combines Tekonsha’s renowned engineering with rugged, vehicle-grade electronics. It’s a reliable, purpose-built solution for owners who tow frequently—whether you’re hauling a utility trailer, a boat, or a larger camper. The compact, weather-resistant enclosure stays out of the way under the dash while delivering consistent performance mile after mile.

What makes Primus IQ stand out

• True proportional braking: The controller continuously interprets your brake pedal input and applies trailer brakes in proportion, delivering steadier stopping power and reducing sway compared with non-proportional systems.
• Automatic leveling: Self-leveling capability compensates for vehicle pitch and ladder hitch setups, helping maintain accurate brake response regardless of angle or grade.
• Five programmable settings: Save and switch between up to 5 profiles to suit different trailers, loads, or drivers—so you aren’t guessing the right brake gain each time you hook up.
• Customizable LED display: Adjust brightness to suit your cab lighting and viewing preferences, ensuring quick, at-a-glance brake status awareness during night operations.
• Power boost for heavy-duty towing: Increase braking force for oversized loads or steep descents, giving you confidence when every second counts.
• Integrated safeguards: Built-in protections guard your vehicle’s electrical system and trailer wiring, with self-diagnostic indicators to help you spot issues before they become problems.

Why this matters in real-world towing

Imagine you’re swapping from a light boat trailer to a heavy utility trailer on a steep grade. Primus IQ’s proportional braking ensures the trailer slows in harmony with your tow vehicle, preventing abrupt dives or surges that can unsettle both vehicle and cargo. When you’re navigating busy highways, the automatic leveling maintains stable brake response as payload or road grade changes, so you stay in control with less driver fatigue.

For frequent tow rigs, the five preset profiles streamline switching between setups—parked at the marina, heading to the job site, or cruising on a road-trip. The adjustable LED display keeps you informed at a glance, even in bright daytime conditions. And the power-boost option gives you an extra margin of braking force when you’re carrying heavy loads or descending long grades.

Who benefits most: light- to heavy-tow enthusiasts, RVers, contractors, and anyone who values precise trailer braking without tinkering with gain settings every time the load or road conditions change. If you’ve previously relied on time-based or non-proportional controllers, Primus IQ offers a clear, real-world upgrade in braking performance, stability, and driver confidence.

With Trojan backing, Primus IQ pairs trusted, durable electronics with thoughtful design—giving you a brake controller that’s straightforward to install, easy to use, and built to last. Install once, tow with more peace of mind, and enjoy the enhanced control that comes from truly proportional trailer braking.
