REDARC Tow-Pro Liberty proportional trailer brake controller for Toyota Tundra/Tacoma — Plug-and-play in-dash dial

REDARC Tow-Pro Liberty is a plug-and-play proportional electric trailer brake controller kit engineered to give Toyota Tundra and Tacoma drivers smooth, automatically matched braking for safer towing.

The Tow-Pro Liberty kit bundles REDARC’s proven proportional brake controller with a vehicle-specific harness and switch insert for near-factory installation in compatible Toyota trucks. Built for everyday highway towing, this package simplifies fitment for Tundra (2015–2021 and 2022–2023 with optional harness) and Tacoma (2016–2023) owners who want responsive braking without a bulky dash module. The system continuously senses tow vehicle deceleration and applies trailer brakes in proportion, cutting out abrupt jerks and improving trailer stability on highways and city streets.

How does the Tow-Pro Liberty improve towing control on the highway?

The unit uses a proportional sensing algorithm to mirror the vehicle’s braking intensity to the trailer brakes, creating a predictable, smooth stop. This reduces trailer push and pull during deceleration and helps maintain a straight, stable tow at higher speeds.

• Active proportional braking that scales with vehicle deceleration
• Automatic calibration—no manual tuning required for most tow situations
• Compact in-dash dial for discreet, OEM-style appearance
• Built-in sway attenuation to help steady trailers during braking

What does the kit include and how easy is installation?

The kit is shipped with the Tow-Pro Liberty controller, a Toyota-specific Tow-Pro Brake Controller Harness (TPH-015), and a matching switch insert for a factory-integrated look. The harness and insert let most owners or installers perform a straightforward plug-and-play connection without splicing factory wiring.

• Tow-Pro Liberty proportional brake controller (dashboard dial)
• Toyota-suitable harness (TPH-015) for direct connector fitment
• Switch insert to match factory switch openings for neat integration
• Optional harness (TPH-021) and TPSI-011 insert recommended for some 2022–2023 Tundra variations

Will this work with my Toyota Tundra or Tacoma model year?

This kit supports Toyota Tundra models 2015–2021 and Tacoma models 2016–2023 out of the box. For Tundra 2022–2023, the Tow-Pro Liberty will fit when used with Toyota-compatible extras (TPH-021 harness and TPSI-011 switch insert) to match that vehicle’s wiring and switch configuration.

• Direct fit: Tundra 2015–2021, Tacoma 2016–2023
• 2022–2023 Tundra: requires TPH-021 harness + TPSI-011 insert
• 12V vehicle electrical compatibility for standard tow setups
• All components provided for a factory-style installation
