WARNINGS & SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - This manual contains IMPORTANT SAFETY INSTRUCTIONS for
the
Tow-Pro™ Elite
Brake Controller.
DO NOT OPERATE THE CONTROLLER UNLESS YOU HAVE READ AND UNDERSTOOD THIS
MANUAL AND THE CONTROLLER IS INSTALLED AS PER THESE INSTALLATION INSTRUCTIONS.
ENSURE THAT YOUR TRAILER BRAKES ARE INSTALLED AND ARE OPERATING CORRECTLY:
IMPROPERLY INSTALLED AND/OR FAULTY TRAILER BRAKES CAN CAUSE ERRATIC VEHICLE OR
TRAILER BEHAVIOUR WITH THE POTENTIAL TO CAUSE A ROAD ACCIDENT. FOR THIS REASON,
IT IS OF UTMOST IMPORTANCE THAT YOUR TRAILER BRAKING SYSTEM BE INSTALLED/
MAINTAINED BY A QUALIFIED INSTALLER.
ALWAYS CHECK BRAKES AT LOW SPEED EACH TIME A TRAILER IS ATTACHED TO YOUR
VEHICLE.
1. Ensure that the Tow-Pro™ Elite is mounted securely in a fixed location. Failure to
mount securely will result in inaccurate braking force measurements and incorrect
braking of the trailer.
2. Ensure that the Tow-Pro™ Elite is installed inside the vehicle cabin and away from any
environmental conditions that may cause damage, including engine heat, submersion
in water, salt spray and humidity. Exposure to these conditions may cause damage to
the unit’s circuitry and may cause erratic trailer braking.

WARNINGS & SAFETY INSTRUCTIONS
3. A Fuse or Circuit Breaker of appropriate rating must be installed to protect the vehicle
system. Please refer to the installation instructions on page 7 for specific instructions
on where to install the Fuse or Circuit Breaker and for appropriate Fuse or Circuit
Breaker rating. The Fuse or Circuit Breaker must be installed as close as possible to
the battery.
4. Ensure the remote head push-button activates correctly when installed into surfaces
with a thickness greater than 3.0mm. Failure to activate correctly would result in not
being able to activate the override function or change modes.
5. Ensure that the cable used to install the Tow-Pro™ Elite is of adequate gauge to
supply the required current to operate the trailer brakes. Incorrect wiring can result in
overheated wires or excessive voltage drop and may cause injury to persons, damage
to the Tow-Pro™ Elite and/or damage to property.
6. The Tow-Pro™ Elite is suitable for all trailers with electric brakes on up to three axles.
Note that for trailers above 4.5t gross, special testing is required under Australian
Design Rules. For these trailers, please consult with an automotive safety engineer
before using the Tow-Pro™ Elite.
1. Ensure that a correct grounding point is used. Vehicles often have ungrounded
metal reinforcements under the dash and these points are not suitable grounds. Bad
grounding of the unit will result in poor or no operation.
2. The Tow-Pro™ Elite does not act as a trailer lights voltage converter. The Tow-Pro™
Elite is designed to operate the trailer brake lights under certain conditions. If the
trailer brake lights require a different voltage to the input from the vehicle, damage to
the trailer brake lights may result.
3. When installing the Tow-Pro™ Elite Remote Control to a thin panel, washers are
recommended to reinforce the structure of the panel.
4. Do NOT exceed Tow Vehicle and Trailer weights and specifications. Failure to abide by
the towing regulations, including maximum loads, may result in a fine, or in case of
an accident, refusal of the insurance claim, and the possibility of further legal action.
If the tow vehicle or trailer’s maximum load is exceeded, police and transport
authorities have the power to order the combination off the road until the issue is
corrected. This may necessitate leaving the trailer on the side of the road while a
vehicle with suitable towing capacity is sourced or the trailer load is reduced. Please
contact your local authorities for further information.

2 INSTALLATION
2.1 Mounting the main unit
The Tow-Pro™ Elite should be mounted inside the vehicle cabin using either M4 screws
or other secure fitting methods at the mounting points provided. It is essential to mount
the unit in a location which allows access to the intended remote head location.
The Tow-Pro™ Elite can be mounted in any orientation as long as the installation is
secure and the main unit cannot move or change orientation once installed. A change of
orientation will affect the system calibration.
Ensure that the Tow-Pro™ Elite is mounted securely in a fixed location. Failure to mount
securely will result in inaccurate braking force measurements and incorrect braking of
the trailer.
Ensure that the Tow-Pro™ Elite is installed inside the vehicle cabin and away from any
environmental conditions that may cause damage, including engine heat, submersion in
water, salt spray and humidity. Exposure to these conditions may cause damage to the
unit’s circuitry and may cause erratic trailer braking.

2 INSTALLATION
2.2 Wiring the brake controller
A Fuse or Circuit Breaker of appropriate rating must be installed to protect the vehicle
system. Please refer to the installation instructions on page 7 for specific instructions on
where to install the Fuse or Circuit Breaker and for appropriate Fuse or Circuit Breaker
rating. The Fuse or Circuit Breaker must be installed as close as possible to the battery.
Ensure that the cable used to install the Tow-Pro™ Elite is of adequate gauge to supply
the required current to operate the trailer brakes. Incorrect wiring can result in overheated
wires and may cause injury to persons, damage to the Tow-Pro™ Elite and/or damage to
property.
The Tow-Pro™ Elite does not act as a trailer lights voltage converter. The Tow-Pro™ Elite
is designed to operate the trailer brake lights under certain conditions. If the trailer brake
lights require a different voltage to the input from the vehicle, damage to the trailer brake
lights may result.
2.2.1 Red Wire (Vehicle Brake light) Connection
The requirements for a suitable connection of a brake controller trigger wire are quite
specific. This connection point must:
• Provide battery voltage output while the vehicle brakes are applied.
• Have 0 volts output while the vehicle brakes are not applied
• Accept battery voltage input when the brake controller manual over-ride is operated
and illuminate at least the trailer brake lights.
• Accept the battery voltage input as above without causing any damage, spurious
vehicle operation or erroneous fault indication.
A relay should not be installed to drive the red wire as this would prevent the override
feature from working and may introduce dangerous voltage spikes.
For many vehicles, the brake light terminal of the trailer lighting socket provides a suitable
connection, however this is not necessarily suitable for all vehicles. Unfortunately REDARC
cannot recommend where to make this connection on a specific vehicle’s OEM wiring. For
further information contact the vehicle manufacturer.

2.3 Mounting the Remote Head
The Tow-Pro™ Elite remote head is designed to be mounted at a distance from the main
unit, allowing for a neat, convenient installation and not impeding on lower leg airbags or
driver leg room. The Tow-Pro™ Elite remote head is designed to be mounted on or around
the vehicle dashboard and when installed correctly, complies with Australian Design Rule
(ADR) 21, which sets requirements for devices mounted on the dashboard. The Tow-Pro™
Elite remote head can be mounted directly to the dashboard, to the centre console or
through a spare knock-out switch panel and requires only two holes to be drilled as per
the below diagram.

2 INSTALLATION
2.4 Active Calibration
When the unit is first powered, Active Calibration must first become confident in
the vehicle direction of travel. Until this time the LED will flash Blue/Green.
Time Time
During Calibration: Once Calibrated:
Active Calibration constantly monitors the vehicle’s direction of travel and allows the
Tow-Pro™ Elite to ‘learn’ and continuously confirm its mounting orientation. This process
occurs whilst the vehicle is moving and the brake is applied and will occur with or without
a trailer connected.
When the Tow-Pro™ Elite is first installed it will begin learning its mounting orientation
through Active Calibration as soon as you start driving, at this point Proportional Mode is
selected but not yet fully operational.
Until the Tow-Pro™ Elite has determined its mounting orientation the unit will function as
if in User-Controlled mode, this is indicated by the LED glowing green with blue flashes.
As the Tow-Pro™ Elite becomes more confident of its direction of travel the length of the
Blue flash will increase, to the point that the LED is solid Blue which indicates it is now
operating completely in Proportional mode.
Under normal driving conditions the Tow-Pro™ Elite will learn its mounting orientation
within 20 brake applications. Note that the braking must be perceptible (applying the
brake while stopped will not assist calibration).
If power is disconnected (for example, if the vehicle battery is changed) calibration
memory will be lost and the unit will recalibrate itself using active calibration. This is
similar to a radio losing its clock or preset station memory.
If no trailer is connected, Active Calibration will occur as normal without any indication
from the LED. The LED will already be Blue when the trailer is connected. Essentially,
whether a trailer is connected or not, just drive normally and Active Calibration will ensure
the Tow-Pro™ Elite learns the correct direction of travel.

3 OPERATION
3.1 Adjusting the Braking Force
In both modes the braking level can be adjusted to
suit varying trailer loads, braking requirements or
user comfort by adjusting the control knob on the
0

remote head.
The lower end of the scale (below level 5) should
be used as a starting point and adjusted accordingly
once braking requirements are established.
If a lighter braking level is required, turn the control knob to a lower number (anti-clockwise)
to reduce the trailer braking force. Similarly, turn the gain control knob to a higher number
(clockwise) to increase the trailer braking force.
The braking level will be indicated by the LED changing to a shade of RED when the
brakes are applied. The higher the braking level, the more RED the LED will glow.
A setting of ‘0’ will result in no trailer braking output.
3.2 Manual Override
Pressing the gain control knob whilst driving will
apply the manual override brake. The manual
override brake will apply the trailer brakes only; if
wired correctly will also apply the trailer brake lights
and will turn the LED indicator a shade of RED.
Depending on the vehicle wiring it may possibly also
apply the vehicle brake lights. The manual override
is designed to be used when the trailer brakes need
to be applied without the vehicle brakes, such as
correcting trailer ‘sway’ whilst travelling.
In Proportional mode the manual override will apply the trailer brake to a level equivalent
to ‘light’ vehicle braking.
In User Controlled mode the manual override will apply the trailer brakes to the level set
on the gain control knob.
In both modes the braking force can be adjusted by turning the gain control knob, either
higher or lower, even whilst applying the manual override brakes.
Manual override should not be used in place of the regular vehicle brakes.

3 OPERATION
3.3 Operating Modes
The Tow-Pro™ Elite offers two modes of operation - Proportional and User Controlled.
On the first application of power to the black wire, the Tow-Pro™ Elite will start-up in
Proportional mode. Every time a trailer is connected, the Tow-Pro™ Elite will start up in
the mode that was last selected (provided the black wire has remained connected to
power/battery positive).
3.3.1 Proportional Mode (Blue LED)
If the status indication LED on the control knob is glowing
BLUE, the Tow-Pro™ Elite is in Proportional Mode.
In Proportional Mode, the Tow-Pro™ Elite will apply the trailer
brakes at a level proportional to the vehicle deceleration.
The control knob setting, 0 to 10, will set the brakes from
a lighter to a heavier trailer brake application. Simply put,
the harder the vehicle brakes are applied, the harder
the trailer will brake. This mode is designed for highway
travelling or everyday use and requires minimal input from
the user whilst travelling.
3.3.2 User Controlled Mode (Green LED)
If the status indication LED on the control knob is glowing
GREEN, the Tow-Pro™ Elite is in User Controlled Mode.
In User Controlled Mode, the Tow-Pro™ Elite will apply the
trailer brakes to the level set by the user on the gain control
knob. The control knob setting, 0 to 10, will set the brakes
from Zero to Full trailer brake application. Simply put, the
trailer will brake to the level set by the control knob
(regardless of how hard the vehicle brakes). This mode
is often preferred for off road or precision use and may
require frequent attention from the user.

a surface which is too thick and that the button is able to be depressed fully. Refer
to section 2.3 for details. Ensure you reset the dial to a suitable braking level after
changing modes.
3.4 Park Brake Feature
If the Tow-Pro™ Elite detects that the vehicle brakes are applied for longer than 3 seconds
whilst the vehicle is stationary, it will apply the trailer brakes in an intelligent manner
to reduce the required braking effort whilst decreasing the risk of rolling forward or
backward whilst stopped. If the controller determines the trailer brakes are not required
to keep the vehicle stationary, the output will be decreased to Zero.

3 OPERATION
3.5 Electric / Hydraulic Brakes
The Tow-Pro™ Elite is designed to operate both electric and electric / hydraulic braking
systems in both Proportional and User Controlled Modes. The unit requires no user input
to select the electric/hydraulic mode.
Most Electric / Hydraulic braking systems will require a separate 12V power feed for the
hydraulic pump. For example:

Always refer to the manufacturer’s specifications for your Electric / Hydraulic
Braking system prior to installation and usage of the Tow-Pro™ Elite.
3.6 24V Vehicle Systems
The Tow-Pro™ Elite is designed to operate 12V trailer brakes from both 12V and 24V
vehicle electrical systems; The acceptable voltage input range is between 9V and 32V.
The Tow-Pro™ Elite will operate from a 24V electrical system without the need for other
external devices.
For 24V installation, refer to section 2.2 ‘Wiring the brake controller’.

3.9 Troubleshooting
The Tow-Pro™ Elite features sophisticated diagnostics to warn the operator of faults in
the vehicle and trailer brake wiring. Wiring faults are indicated by a series of colour coded
flash patterns on the Tow-Pro™ Elite LED.
Most faults turn out to be something simple such as a poor connection from a dirty trailer
socket, however a fault indication should not be ignored! It is a warning; if left unattended
such wiring faults can become worse and may lead to deterioration or loss of trailer braking.
Please refer to the table on pages 17 & 18 for the list of flash patterns, showing the cause
& recommended course of action for each of the conditions which may be detected.
Even intermittent faults are detected and may be indicated until cleared.
Most fault codes can be cleared by unplugging the trailer for 1 minute then
reconnecting.

4 PERIODIC MAINTENANCE/CHECKS
Ensure that your trailer brakes are installed and are operating correctly:
Improperly installed and/or faulty trailer brakes can cause erratic vehicle or trailer behaviour
with the potential to cause a road accident. For this reason, it is of utmost importance that
your trailer braking system be installed/maintained by a qualified installer.
Always check brakes at low speed each time a trailer is attached to your vehicle.
Immediately After Installation (To be done by a qualified Auto-Electrician)
Test the installation/vehicle wiring. Testing your vehicle wiring is best done by connecting
a test light (Max 21W filament globe) to the brake output, pushing the manual override and
having someone check that the vehicle brake lights and the test lamp both light up.
Before each trip
It is important to ensure that your system is operating correctly before you set out. The
following should be checked, along with standard mechanical maintenance, each time
you attach your trailer:
• Correct brake light operation on both your vehicle and trailer
• Correct operation and setting of the electric brake controller
• Correct operation of your trailer brakes
• Check that your breakaway system is operating correctly and that the breakaway
battery is healthy (if applicable)
• Ensure that the tow hitch, and safety chains and weight distribution systems are
setup correctly
Periodically
It is important to have a qualified technician check the function of your trailer system on a
periodic basis to ensure that everything is operating correctly. REDARC recommend that
you visit a qualified technician before the beginning of each holiday season to ensure that
any towing aids or systems are working correctly.
Other considerations
Please consider the below items whilst towing a trailer:
• Ensure that your vehicle is capable of towing the trailer
• Ensure that you adjust your driving style to allow more time to change lanes and brake
• Always remember that your electric brake controller is designed to supplement your
vehicle brakes; do NOT use the Tow-Pro™ Elite manual override in place of your
vehicle foot brake
• REDARC recommend professional towing training before attempting to tow a trailer;
companies such as Tow-Ed offer these services

amount to a major failure.
The benefits of this Warranty are in addition to other rights and remedies available at law in respect of the Products and shall not derogate from any applicable mandatory statutory
provisions or rights under the Australian Consumer Law.

2. Redarc warrants that its Products will be free, under normal application, installation,
use and service conditions, from defects in materials and workmanship affecting
normal use, for 2 years from the date of purchase (Warranty Period).
3. Where a Product malfunctions or becomes inoperative during the Warranty Period,
due to a defect in materials or workmanship, as determined by Redarc, then subject

6.2 accident, misuse, abuse, negligence, vandalism, alteration or modification;
6.3 non-observance of any of the instructions supplied by Redarc, including
instructions concerning installation, configuring, connecting, commissioning,

equipment or machinery;
6.5 repairs to the Product that are not strictly in accordance with Redarc’s

Such claims must include the following:
7.1 details of the alleged defect or fault and the circumstances surrounding the
defect or fault;
7.2 evidence of the claim, including photographs of the Product (where the subject
of the claim is capable of being photographed);
7.3 the serial number of the Product, specified on the label affixed to the Product;
and

or reseller of Redarc, which clearly shows the date and place of purchase.
The return of any Products without the prior written instructions of Redarc will not
be accepted by Redarc.
8. Without limiting any other clause in this Warranty, Redarc has the right to reject any
Warranty claim made by a Purchaser pursuant to this Warranty where:
8.1 the Purchaser does not notify Redarc in writing of a Warranty claim within the
Warranty Period;
8.2 the Purchaser does not notify Redarc in writing of a Warranty claim within 1
month of becoming aware of the relevant circumstances giving rise to the
claim, so that any further problems with the Product are minimised;
8.3 the serial number of the Product has been altered, removed or made illegible
without the written authority of Redarc;
8.4 the Purchaser is unable to provide proof of purchase documentation in
accordance with clause 7.4 or evidence that the Product was properly installed
and removed (if relevant), and that proper maintenance has been performed
on the Product, by, or under the supervision of, a qualified auto electrician or
technician, in accordance with the instructions of Redarc.
9. If the Product is found to be working satisfactorily on return to Redarc or upon
investigation by Redarc, the Purchaser must pay Redarc’s reasonable costs of
testing and investigating the Product in addition to shipping and transportation
charges. Where Redarc is in possession of the Product, the Product will be
returned to the Purchaser on receipt of the amount charged.
10. Any replaced Products or components of Products shall become the property of
Redarc.
11. Redarc may, in exercise of its sole discretion, deliver another type of Product or
component of a Product (different in size, colour, shape, weight, brand and/or
other specifications) in fulfilling its obligations under this Warranty, in the event
that Redarc has discontinued manufacturing or supplying the relevant Product or
component at the time of the Warranty claim, or where such Product or component
is superior to that originally purchased by the Purchaser.
Other conditions of Warranty
12. If the Purchaser acquired a Product for the purpose of resupply, then this Warranty
shall not apply to that Product.
13. In particular, the sale of a Product via an online auction, online store or other
internet website by a party that is not an authorised distributor or reseller of the
Product will be deemed to be a resupply within the meaning of the Australian
Consumer Law and will render this Warranty void, as Redarc has no control over the
storage, handling, quality or safety of Products sold by such persons.
14. A Purchaser shall only be entitled to the benefit of this Warranty after all amounts
owing in respect of the Product have been paid.
15. While Redarc warrants that the Products will be free from defects in materials and
workmanship in the circumstances set out in this Warranty, to the maximum extent
permitted by law Redarc does not warrant that the operation of the Products will be
uninterrupted or error-free.
16. To the maximum extent permitted by law, Redarc’s determination of the existence of
any defect and the cause of any defect will be conclusive.
17. Spare parts or materials for the Products are guaranteed to be available for a period
of at least 2 years after purchase of the Products.
18. The agents, officers and employees of any distributor or reseller of the Products and
of Redarc are not authorised to vary or extend the terms of this Warranty.
19. Redarc shall not be responsible or liable to the Customer or any third party in
connection with any non-performance or delay in performance of any terms and
conditions of this Warranty, due to acts of God, war, riots, strikes, warlike conditions,
plague or other epidemic, fire, flood, blizzard, hurricane, changes of public policies,
terrorism and other events which are beyond the control of Redarc. In such
circumstances, Redarc may suspend performance of this Warranty without liability
for the period of the delay reasonably attributable to such causes.
20. If a clause or part of a clause in this Warranty can be read in a way that makes it
illegal, unenforceable or invalid, but can also be read in a way that makes it legal,
enforceable and valid, it must be read in the latter way. If any clause or part of
a clause in this Warranty is illegal, unenforceable or invalid, that clause or part is
to be treated as removed from this Warranty, but the rest of this Warranty is not
affected.
