Lrichy Time-Delay Trailer Brake Controller 8507111 — 1–4 Axles, LED Display & Plug‑and‑Play

The Lrichy 8507111 is a time-delay digital trailer brake controller that steadily applies braking power to 1–4 axles for safer, more predictable towing.

If you tow trailers with electric brakes and want a straightforward, dependable controller, the Lrichy 8507111 offers a time-delayed, digitally displayed solution that fits 2–8 brake setups (1–4 axles). Designed as an upgraded replacement for the 8507111 Time-Delay Brake IV, this unit delivers a fixed-rate ramp of brake force, an easy-to-read LED display, and simple mechanical mounting with a plug-and-play port for quick disconnects. It’s intended for drivers who prefer a basic, reliable controller rather than proportional or inertia-based models.

How does the time-delay braking work and why choose it?

The time-delay feature increases braking force gradually at a preset rate after you apply the tow vehicle brakes. This results in smoother trailer braking and reduces abrupt jerks when a proportional controller isn’t required or available.

• Preset ramp rate applies brake power over a timed interval for consistent response.
• Manual lever lets you add or hold trailer braking independent of tow-vehicle pressure.
• Digital readout shows current settings and basic diagnostic/alarm indications.
• Best for utility trailers, small campers, and basics towing setups.

Is the Lrichy 8507111 easy to install and configure?

Yes — the controller ships with mounting brackets and screws and includes a plug-and-play port for simple disconnects. No special horizontal orientation is required, so it can be mounted in a variety of dash positions to suit your cab layout.

• Includes brackets and hardware for secure mounting in most vehicles.
• LED display and clear manual make initial setup and adjustments straightforward.
• Plug-and-play port simplifies removal for service or vehicle changes.
• Note: vehicle-specific harness is not included; purchase separately if needed.

Which vehicles and trailer axles does this controller support?

The Lrichy 8507111 is compatible with many common makes and models, working with trailer setups that have 2, 4, 6, or 8 electric brakes (covering 1–4 axles). It’s a direct replacement for the earlier 8507111 Time-Delay Brake IV unit.

• Compatible brands include Ford, GM, Chevy, Dodge, RAM, Toyota, Jeep and more.
• Supports 1–4 axle trailers with 2–8 electric brake assemblies.
• Confirm vehicle wiring harness compatibility before purchase; harness not included.
• Ideal for customers replacing the 8507111 Time-Delay Brake IV model.

What controls and diagnostics are included for in-use adjustments?

The controller uses a manual sliding lever for instant brake application plus an LED digital display to present settings, simple diagnostic readouts, and alarm indicators. That combination helps you tailor trailer braking quickly while monitoring for basic faults.

• Manual lever provides on-demand braking override and adjustment while towing.
• LED display shows current setting and alerts during operation.
• Simple diagnostic feedback helps identify common wiring or brake issues.
• Designed for drivers who want clarity without complicated electronics.

Who is this for? The Lrichy 8507111 upgraded time-delay brake controller is aimed at owner-operators and weekend tow users who need a dependable, easy-to-install controller for trailers with electric brakes. It suits those replacing an older 8507111-style controller or anyone who prefers a time-delayed braking profile over proportional systems. If you tow light- to medium-duty trailers, value straightforward setup and visible status feedback, and can provide a vehicle-specific harness when required, this unit is a practical, cost-conscious choice.
