Lrichy Trailer Brake Controller 8507111 — Time-Delay 1–4 Axles with LED Display & Manual Lever

The Lrichy 8507111 is an upgraded time-delay digital trailer brake controller that delivers gradual, adjustable braking for trailers with one to four axles.

This compact controller replaces the older 8507111 Time-Delay Brake IV and is built for straightforward towing situations where predictable, incremental trailer braking is preferred. Its LED digital display, manual lever, and easy-to-mount hardware make it a practical choice for drivers who tow small to medium trailers and want reliable, repeatable brake response without complex calibration.

How does the time-delay braking system work?

The controller applies braking force progressively over a preset interval rather than instantly, which results in a smoother engagement between tow vehicle and trailer. You set the braking intensity, and when you activate the trailer brakes the unit ramps the output at that fixed rate to the trailer electromagnets.

• Digital time-delay algorithm increases brake output gradually.
• Adjustable braking force to match trailer weight and load.
• Manual lever for immediate, on-demand trailer braking.
• LED readout shows settings and diagnostics for easy monitoring.

Will this controller work with my vehicle and trailer?

The Lrichy 8507111 supports trailers with 2, 4, 6, or 8 brakes (covering 1–4 axles) and fits a wide range of popular vehicle makes. It replaces the prior 8507111 Time-Delay Brake IV and connects via standard wiring; however, vehicle-specific plug-and-play harnesses are not included.

• Compatible with Ford, GM, Chevy, Dodge, RAM, Toyota, Jeep and more.
• Designed for 1–4 axles (2–8 brakes) — suitable for most small/medium trailers.
• Requires correct vehicle wiring or optional harness for some models.
• Not a model-specific plug-and-play kit; verify your vehicle connector separately.

How do I install and operate the controller?

Installation is intended to be user-friendly: included brackets and screws allow secure mounting, and a plug-and-play port makes disconnecting straightforward. The unit can be mounted in any orientation and the LED display plus the manual lever simplify everyday operation and troubleshooting.

• Includes mounting brackets and hardware for easy attachment.
• Plug-and-play port enables quick disconnection from trailer wiring.
• No strict horizontal mounting required — install in any direction.
• Clear LED display and included manual guide for setup and diagnostics.

Who is this for? The Lrichy 8507111 is aimed at weekend haulers, DIY installers, and drivers of light-to-medium trailers who want a simple, reliable time-delay brake controller without the complexity of proportional systems. It’s a good fit when you need consistent, adjustable braking for trailers with up to four axles and prefer straightforward installation, clear diagnostics, and a manual lever for immediate brake application. If you require automatic proportional braking for heavy towing or more advanced electronic sync, consider a proportional controller; if you want a dependable time-delay solution that’s easy to set up and operate, the Lrichy 8507111 is designed to meet those needs.
