Dash-mounted electric trailer brake controller with proportional and user-controlled braking modes for compatible 12V and 24V tow vehicles, electric trailer brakes, and electric-over-hydraulic brake systems.
The Redarc EBRH-ACCV3-NA Tow-Pro Elite V3 is a premium electric trailer brake controller designed for clean, low-profile installation with the main control module hidden behind the dash and a small remote control knob mounted within reach of the driver.
Unlike basic brake controllers, the Tow-Pro Elite offers two braking styles in one unit. Proportional mode automatically adjusts trailer braking based on vehicle deceleration for everyday highway towing, while user-controlled mode lets the driver manually control trailer braking for off-road, gravel, mud, sand, snow, or steep descent conditions.
Choose proportional braking or user-controlled braking based on road and terrain
Small dash knob keeps the cab cleaner than traditional under-dash controllers
Designed for compatible 12V and 24V tow vehicle electrical systems
Self-calibrating technology allows flexible main-unit mounting orientation
The Tow-Pro Elite is a brake controller for trailers with electric or electric-over-hydraulic braking systems. It is not a trailer light converter, brake actuator, breakaway system, wiring adapter, or plug-and-play vehicle harness by itself. Vehicle-specific wiring harnesses, circuit protection, brake output wiring, and installation parts may be required depending on the tow vehicle. Always verify tow vehicle wiring, trailer brake type, axle count, connector style, and installation requirements before ordering.
Before Starting: Confirm the tow vehicle and trailer brake system are compatible with the Tow-Pro Elite. Brake controller installation involves vehicle power, ground, brake signal, and trailer brake output wiring. Use the REDARC instructions and a qualified installer if wiring or brake system diagnosis is uncertain. Basic Installation Steps: 1. Confirm Application: Verify tow vehicle voltage, trailer brake type, axle count, 7-way wiring, and required harness or pigtail. 2. Disconnect Power: Disconnect vehicle battery power before making electrical connections. 3. Mount Main Unit: Secure the main control module inside the vehicle cabin in a fixed location away from heat, water, salt spray, and humidity. 4. Mount Remote Head: Install the remote knob in a reachable dash location with proper panel thickness and clearance. 5. Wire Controller: Connect power, ground, brake signal, and trailer brake output according to REDARC instructions and vehicle wiring requirements. 6. Add Circuit Protection: Install the required fuse or circuit breaker near the battery as directed by the installation instructions. 7. Calibrate Controller: Drive normally so active calibration can learn the vehicle direction of travel. 8. Test Trailer Brakes: With the trailer connected, test braking at low speed before towing on public roads. 9. Select Braking Mode: Use proportional mode for normal towing or user-controlled mode for conditions where manual trailer brake control is preferred.
Package Contents: • 1 REDARC Tow-Pro Elite V3 main control unit • 1 remote control head / dash knob assembly • Universal pigtail wiring harness as supplied by REDARC • Universal switch insert panel as supplied by REDARC • Installation hardware and instructions as supplied by manufacturer NOT Included — May Also Need: • Vehicle-specific plug-and-play brake controller harness • 30A circuit breaker or fuse kit, if not already available • 7-way trailer connector or vehicle-side towing wiring • Trailer brake wiring repairs or upgrades • Mounting panel insert specific to certain vehicle dashboards • Breakaway battery/system components • Trailer brake assemblies or electric/hydraulic actuator • Installation tools and electrical testing equipment This listing is for the Tow-Pro Elite brake controller kit only unless otherwise stated. Confirm required vehicle harnesses, circuit protection, and trailer brake wiring before ordering.
To confirm compatibility before ordering, have the following ready: • Tow vehicle year, make, and model • Whether the vehicle has a factory tow package • Vehicle voltage system: 12V or 24V • Trailer connector type, especially 7-way wiring availability • Trailer brake type: electric or electric-over-hydraulic • Number of trailer axles with brakes • Whether a vehicle-specific REDARC harness is available • Desired remote knob mounting location and dash panel thickness • Any existing brake controller wiring or previous controller model Why this matters: The Tow-Pro Elite controller is broadly adaptable, but the wiring harness, mounting hardware, circuit protection, and brake output wiring are vehicle- and trailer-specific.
Match this brake controller by tow vehicle voltage, wiring setup, trailer brake type, axle count, harness needs, and mounting location. Do not select by part number alone if the vehicle wiring is unknown.
If braking issues continue after installation, check power, ground, brake signal, trailer brake output, 7-way wiring, trailer brake adjustment, brake assemblies, circuit protection, and REDARC diagnostic guidance.
Trailer brake controller installation affects towing safety and should be completed according to REDARC instructions and applicable vehicle/trailer requirements. Improper wiring, poor grounding, missing circuit protection, faulty trailer brakes, or incorrect setup can reduce or eliminate trailer braking. Always test trailer brakes at low speed each time a trailer is connected, do not exceed vehicle or trailer weight ratings, and use a qualified installer if wiring or braking system condition is uncertain.
