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.
