Tow-Pro Liberty Electric Brake Controller Kit — Universal Fit
The Tow-Pro Liberty delivers Proportional Mode braking for smooth, on-road control. It’s designed for easy installation and everyday towing confidence, reducing push and pull during braking. This universal brake controller is compatible with SUVs and trucks and can be paired with the TP-H-025 wiring harness or other vehicle-specific harnesses for factory-style integration. Includes the main brake controller, remote head assembly and related components, and supports 1–2 axles for most common trailer braking applications.
Brakeman IV Time-Delay Brake Controller
This time-delayed proportionality system ramps braking power over a fixed period to reduce trailer sway and uneven stops. It features a plug-and-play port for simple installation and a compact dash-mounted unit that can be positioned above or below the dash. The built-in digital display provides real-time diagnostics and short-circuit protection, with color indicators to show power or secure trailer connections.
Tow-Pro Liberty (Toyota) — Plug & Play
Designed for Toyota models, this Tow-Pro Liberty kit provides a plug-and-play solution for highway towing. It includes a Toyota-specified harness and switch insert for a factory-like integration, ensuring seamless compatibility with select Tundra, Tacoma, Land Cruiser models and similar vehicles. The kit emphasizes proportional braking and straightforward installation for everyday towing.
Tow-Pro Elite Electric Brake Controller Kit
The Tow-Pro Elite offers dual braking modes, blending Proportional braking for on-road control with a user-controlled mode for off-road scenarios. It fits 1–3 axles and is designed for easy factory-style integration in Toyota SUVs and trucks. This kit includes a suitable harness, a universal mount, and switch panels to suit specific vehicle models, providing versatile, adaptable braking performance.
Primus IQ Proportional Brake Controller
The Primus IQ provides proportional braking based on the towing vehicle’s braking intensity and rate. It includes an inertia sensor for smooth stops and a compact, plug-and-play design. The LED display delivers real-time diagnostics and alerts, helping drivers monitor braking behavior and ensure trailer brakes respond predictably in varying conditions.
Buying Guide: Key Considerations For Selecting An Electric Brake Controller
- Vehicle and trailer compatibility: Confirm axle count (1–2, 1–3, or 1–4) and whether the model supports your SUV, truck, or jeep, as well as camper trailers or boat trailers.
- Braking mode: Decide between proportional (for smooth, vehicle-responding braking) and time-delay (for a predictable ramp-up). Dual-mode options provide flexibility for off-road use.
- Installation options: Plug-and-play harnesses save time, but some setups require vehicle-specific wiring or additional mounting hardware. Check for dash-mounted display locations and accessibility.
- Maintenance and diagnostics: Look for clear LED indicators or digital readouts that provide real-time status and fault detection to prevent misbehavior on the road.
- Availability of accessories: Ensure compatible harnesses, switch insert panels, and mounting hardware are available for your exact vehicle model.
- Off-road functionality: If you frequently tow in challenging terrain, consider dual-mode or specialized kits that offer manual or off-road braking adjustments.
- Durability and weather resistance: Choose units designed to withstand vibrations, heat, and moisture typical in RV and trailer environments.
- Warranty and support: Verify the manufacturer’s warranty terms and the availability of service support in the US.
