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 speciﬁ c 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 wire(s) and all connections used to install the Tow-Pro

Elite are suitably

rated to supply the required current to simultaneously operate the trailer electric brakes

and stop lamps. Incorrect wiring can result in reduced (or total loss of) trailer braking and/

or damage to property or persons.

The Tow-Pro

Elite does not act as a trailer lights voltage converter. If the trailer brake

lights operate on a different voltage, damage to the vehicle; trailer and/or Tow-Pro

Elite

and associated wiring may result. This may also result in reduced (or total loss of) trailer

braking.

2.2.1 Red Wire (Vehicle Brake light) Connection

The requirements for a suitable connection of a brake controller trigger wire are quite

speciﬁ c. This connection point must:

• Provide ‘Start 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 speciﬁ c vehicle’s OEM wiring. For

further information contact the vehicle manufacturer.

Start Battery voltage output means, directly from the Start Battery and within 0.4V of Supply (Black wire)

voltage.
