HRepair Universal Trailer Brake Controller — Replacement for 90160 Primus IQ, 1–3 Axles, Proportional Smooth Braking

The HRepair Universal Trailer Brake Controller is a proportional, plug-and-play unit that replaces the 90160 Primus IQ and delivers smooth, adjustable braking for trailers with 1–3 axles.

If you tow trailers with a single to triple axle—utility trailers, small campers, or equipment haulers—this compact controller gives you precise trailer braking matched to your vehicle's deceleration. Designed as a direct replacement for common in-dash and under-dash controllers, it combines an intuitive digital display, manual override, and selectable boost levels so you can fine-tune braking performance for different loads and road conditions.

How does this controller measure and apply trailer braking?

The HRepair unit uses a proportional sensing method that measures your vehicle's braking intensity and applies a corresponding amount of trailer brake power. That means trailer brakes engage smoothly rather than abruptly, reducing jarring stops and improving stability when towing.

• Proportional sensing for smooth, matched brake application.
• Self-leveling circuitry adapts to vehicle orientation for consistent performance.
• Three boost settings to increase braking force for heavier loads.
• Manual override lever for immediate trailer-only braking control.

Will this fit my vehicle and trailer setup?

HRepair's controller is built to be widely compatible with late-model trucks and SUVs, including Ford, GM, Chevy, Dodge RAM, Toyota, and Jeep, and supports trailers with one to three axles. It installs quickly via plug-and-play wiring or optional bracket mounting, making it a convenient direct replacement for the 90160 Primus IQ and similar models.

• Universal compatibility with common truck and SUV platforms.
• Supports trailers with 1–3 axles (light to medium-duty applications).
• Plug-and-play harness or snap-in clip for fast installation.
• 180-degree mounting flexibility to suit dash or under-dash locations.

How do I control and monitor braking performance while towing?

Controls are straightforward: a clear digital display shows status and diagnostics, a manual lever enables trailer-only braking, and three boost modes let you increase or decrease brake intensity depending on cargo weight. Continuous diagnostics help you spot wiring or connection problems early, keeping you safer on the road.

• Bright, easy-to-read display with real-time connection feedback.
• Manual override for instant trailer brake engagement when needed.
• Diagnostic alerts to identify wiring or brake malfunctions quickly.
• Adjustable boost settings for flexible braking response.

What kind of reliability and support can I expect?

• Advanced circuit protection to resist electrical faults and surges.

Who this is for: Drivers who tow small-to-medium trailers and need a dependable, easy-to-install brake controller that improves stopping smoothness and trailer stability. It suits owners replacing a Primus IQ (90160) or upgrading from time-based controllers to a proportional system—especially useful for truck and SUV drivers who haul varying loads and want quick, accurate braking control.
