Lrichy 90160 Proportional Trailer Brake Controller — 1–3 Axles, Digital Inertia Sensing & LED Display

The Lrichy 90160 Proportional Trailer Brake Controller is a digital inertia-sensing unit that delivers smooth, proportional braking for trailers with 1–3 axles.

If you tow trailers with electric brakes, the Lrichy 90160 gives you responsive, automatic trailer braking that matches your vehicle's deceleration. Built to work with 2-, 4- or 6-brake setups, this controller replaces common models like the Tekonsha 90160 Primus IQ and is designed for easy installation, readable diagnostics, and flexible mounting. It’s aimed at drivers who want predictable trailer behavior without constant manual adjustments.

How does the Lrichy controller sense and apply braking?

The unit uses internal inertia sensors that monitor vehicle deceleration and speed, then proportionally apply current to the trailer brakes. That means braking force ramps up in line with how hard you slow down, which creates smoother stops and better trailer stability.

• Inertia-based sensor measures tow vehicle deceleration and applies proportional output
• Digital control reduces abrupt or delayed trailer braking
• Works in normal driving and during tougher emergency stops

What vehicles and trailers will this controller work with?

Lrichy designed this controller to be broadly compatible with many light- and medium-duty tow vehicles and electric-braked trailers. It fits setups that require 2, 4, or 6 brake circuits and can be used as a replacement for widely used controllers; check your vehicle harness needs before ordering.

• Compatible with Ford, GM, Chevy, Dodge, RAM, Toyota, Jeep and more
• Supports trailers with single to triple axle electric brakes (2/4/6 brakes)
• Note: vehicle-specific plug-and-play harness is not included

How simple is installation and day-to-day operation?

The controller offers a clear LED digital display and straightforward controls so you can adjust braking or switch to manual mode quickly. Mounting options and a removable connector let you install it in the dash or remove it for storage when not towing.

• LED digital display shows settings, diagnostics, and alerts for quick checks
• Includes snap-in dash clip plus adjustable screw-mounted bracket
• Removable electrical connector and Plug & Play port for two plug adapters

What customer support and warranty come with the unit?

Lrichy backs the controller with a two-year warranty and a clear returns policy so you can replace or refund defective units. The package includes a user manual for setup and troubleshooting, and customer service is available for installation questions.

• 2-year warranty coverage and customer support via Amazon
• Free exchange and refund for product-quality issues
• Instruction manual included for setup and basic diagnostics

Who is this for? The Lrichy 90160 is aimed at weekend boat haulers, small business owners with light trailers, and owner-operators who tow campers or equipment and want a proportional braking experience without extra complexity. If you tow trailers that use electric brakes and prefer an automatic, inertia-based controller with a readable digital display, this unit offers a practical, cost-effective replacement that balances responsive performance, straightforward installation, and warranty support.
