An electric brake controller manages the electrical signal sent from the tow vehicle to a trailer's electric brakes. A correctly selected trailer brake controller helps the trailer respond in step with the vehicle and gives the driver control over braking output. The right unit and installation depend on the vehicle, trailer brake system, connector and existing tow wiring.
Time-delay and proportional controllers produce that output differently. A time-delay unit applies a preset output over a set ramp period after the brake pedal is pressed. A proportional unit responds to the tow vehicle's deceleration. The controllers available in this collection use proportional control.

KEY CATEGORIES AND WHAT THEY'RE BUILT FOR
REDARC TOW-PRO ELITE V3
The Redarc Tow Pro Elite V3 uses a separate main unit behind the dash and an accessible in-cab control. It offers automatic and user-controlled modes, giving the driver different ways to manage trailer braking for normal road use and more specialised towing conditions.
HAYMAN REESE GUARDIAN IQ
The Hayman Reese brake controller uses a display-based unit with integrated adjustment. It suits drivers who want the brake output information and controls together in a visible in-cab position. Harness availability depends on the vehicle application.
PROPORTIONAL VS TIME-DELAY
A time-delay controller sends a preset level of trailer braking after the brake pedal is applied. Its response does not directly match the vehicle's actual rate of deceleration. That can require more compromise when setting output for changing traffic, loads and road conditions.
A proportional electric brake controller measures vehicle deceleration and adjusts the trailer output accordingly. Light vehicle braking produces lighter trailer braking, while harder deceleration produces a stronger response. Correct output adjustment remains important because trailer load, brake condition and road surface all affect how the combination behaves.
TOW-PRO ELITE VS GUARDIAN IQ
The Redarc Tow-Pro Elite V3 and Hayman Reese Guardian IQ provide proportional control. Choose by use case, preferred control layout and confirmed vehicle compatibility.
Choose the Redarc Tow Pro Elite V3 when a discreet dash layout is a priority. Its main unit is concealed and the separate control is positioned within the driver's reach. Its operating modes provide a choice between proportional automatic operation and driver-controlled output.
Choose the Hayman Reese Guardian IQ when an integrated display and adjustment interface better suits the cabin layout or driver preference. The visible display makes it easier to check the selected output without relying on a separate concealed unit and remote knob arrangement.
Neither controller should be selected on brand alone. Confirm the vehicle's factory tow package, available mounting position, trailer connector and brake type first. A clean physical fit is only part of the job. The controller must also be electrically compatible with the complete towing setup.
VEHICLE-SPECIFIC HARNESSES MATTER
Brake controller wiring on a modern 4WD needs to account for the vehicle's electrical architecture and factory tow equipment. An incorrect signal pickup or unsuitable connection can cause faults or unreliable brake operation. This is not a circuit that should be connected by assumption.
Where a suitable vehicle-specific harness is available, it can connect through the intended factory interface and reduce unnecessary loom modification. Availability varies by vehicle and controller. Where there is no suitable harness, the custom brake controller wiring must use confirmed signal points, appropriate protection and secure cable routing.
BRANDS WE STOCK AND WHY
This collection includes brake controllers from Redarc and Hayman Reese. Redarc provides the Tow-Pro Elite V3 with a concealed main unit and separate control. Hayman Reese provides the Guardian IQ with an integrated display-based format.
The useful distinction is installation style, control method and compatibility with the vehicle. If you are not sure which format suits your setup, reach out to our friendly staff.
WHAT A QUALITY BRAKE CONTROLLER INSTALLATION INVOLVES
A sound installation starts by confirming the tow vehicle, trailer brake system and connector arrangement. The controller then needs a suitable power supply, brake input, trailer output and earth. Components and wiring must be mounted securely and kept clear of heat, movement and potential damage.
Setup must follow the controller manufacturer's mounting and commissioning instructions. Output should be adjusted for the trailer and checked under controlled conditions. The driver should also understand the manual control, operating mode and signs of a trailer connection fault before towing.
If you want us to fit your electric brake controller, our Ferntree Gully and Pakenham workshops offer vehicle-specific fitting. If you are not sure which controller or harness suits your setup, reach out to our friendly staff. Send a service enquiry with your vehicle and trailer details to discuss the installation approach and booking availability.
Submit a service enquiry with your vehicle details, or email sales@ultimateoffroad.com.au, and our friendly staff will confirm fitment, quote the work and arrange a booking at Ferntree Gully or Pakenham.
