Lrichy Proportional Trailer Brake Controller 1-4 Axles — 90885 Model, LED Display & Self-Leveling

The Lrichy 90885 is a proportional electric trailer brake controller kit that delivers smooth, automatically-adjusted braking for trailers with one to four axles.

This compact, feature-rich controller uses motion-sensing proportional technology to match trailer braking to your vehicle's deceleration, giving steadier, more controlled stops whether you’re towing a boat, RV, or cargo trailer. The kit includes mounting hardware, a removable dash connector for quick storage, and a bright LED display that reports voltage and system status so you always know how the brakes are performing on the road.

How does the proportional sensing improve everyday towing?

Proportional sensing measures the tow vehicle’s deceleration and applies matching force to trailer brakes, reducing jerky stops and wheel lock risk. Because braking is scaled to actual motion, the trailer tracks more predictably behind the vehicle in traffic, hills, and sudden slowdowns.

• Automatically adjusts brake force in real time to vehicle deceleration.
• Smooth proportional reverse braking with disable option for tight maneuvers.
• Reduces trailer sway and abrupt stopping forces for safer handling.

What controls and diagnostics will I see on the unit?

The controller offers an easy-turn power knob, a manual override for immediate trailer braking, and a multi-level boost to add extra stopping power when carrying heavier loads. Continuous diagnostics monitor wiring, magnet function, and voltage to alert you to connection or brake issues before they become serious.

• Bright LED display shows voltage delivery and active alerts.
• Manual override gives on-demand brake application during emergencies.
• Three-stage boost increases braking strength for heavier trailers.
• Built-in diagnostics check for shorts, open circuits, and magnet faults.

How flexible is installation and daily use?

The Lrichy 90885 is designed to mount on or under the dash with a self-leveling range that accommodates up to 90 degrees of vertical tilt—so you don’t need to rebalance it after installation. A quick-disconnect harness and snap-in dash clip make removal and storage fast when you’re not towing.

• Mounts on or under dash with 90-degree self-leveling capability.
• Includes brackets, pocket, and mounting hardware for multiple setups.
• Removable connector enables simple disconnect and compact storage.
• Power-saving mode minimizes battery draw when inactive.

Will this controller work with my trailer and tow vehicle?

This unit supports electric and electric-over-hydraulic brake systems and is specified for trailers with one to four axles. It is offered as a replacement option compatible with popular controllers, but vehicle-specific plug-and-play harnesses are not included—verify your wiring harness or obtain the correct adapter for a plug-compatible fit.

• Compatible with electric and electric-over-hydraulic brakes.
• Rated for trailers with 1–4 axles (supports higher-axle configurations with proper wiring).
• Can replace similar models for many Ford, GM, Dodge, Toyota, Jeep applications (harness not supplied).

Who this is for: The Lrichy 90885 is aimed at drivers who tow regularly and want a more responsive, hands-off braking experience—recreational boat owners, weekend RV travelers, and small-business haulers moving loads where smoother stops and real-time diagnostics matter. If you need easy installation flexibility, clear system feedback, and options to fine-tune braking strength for varied loads, this kit is built for those priorities.
