INSTALLATION PRECAUTIONS:

• Braking capacity is for 2, 4 or 6 trailer brake applications.

• This brake control will apply the trailer brakes while in reverse.

• This brake control is inertia activated. When the vehicle is not moving,

the brake control will not automatically apply the trailer brakes. In this

event, the vertical slide must be depressed to actuate the brakes.

• This brake control is not reverse polarity protected. Reversing the

connection to the vehicle battery or the breakaway battery on the trailer

will damage the brake control.

• Do not mount or activate RF (radio frequency) generating devices near

the brake control (less than 40cm proximity), i.e. Mobile phones,

two-way radios.

• This brake control is designed to operate with electric trailer brakes and

not electric-hydraulic brake systems.

INSTALLATION GUIDE:

The brake control can be

mounted from –20 degrees

nose down to +70 degrees

nose up and parallel to the

direction of travel.

1. Mount the bracket to a secure location with

Phillip screws provided (A) where you will be

able to view the display and easily access

the vertical slide.

2. Attach the brake control to the bracket using the slotted hex screws provided (B).

3. Adjust the brake control to the desired angle and tighten screws until snug.

CAUTION: Drilling or using larger/longer screws may damage the unit.

WIRING GUIDE:

White wire - ground/negative terminal (-) on battery

Blue wire - trailer electric brakes

Black wire - positive terminal (+) on battery

Red wire - cold side of stop lamp switch or brake light

CAUTION: Wire colours vary by manufacturer. Be sure to wire by function only.

1. Be sure to use proper wire gauge when installing your control (12 gauge for

electric brakes and positive power, 16 gauge for the stop lamp switch and ground).

2. Connect the white wire directly to the negative post on the vehicle battery.

Grounding to any other location may cause intermittent brake control operation

or failure.

3. Attach 20-amp circuit breaker (for 6 brake use 30-amp) or in-line fuse to the

positive terminal on the vehicle’s battery.Route black wire from the brake control

to the fuse or breaker.

4. Splice the red wire into the cold side of the vehicle’s stop lamp switch located by

the brake pedal.Find the wire by using a circuit tester and probing for the wire

that powers the vehicle stop lamps when the brake pedal is pressed.

5. Route the blue wire from the brake control to the vehicle side towing connector

at the rear of the tow vehicle.

ELECTRIC WIRING

Trailer wiring must meet the following requirements:

• All wiring must be anchored to the chassis at intervals of not more than 600

millimetres along its length

• All wiring must be insulated at joints

• All wiring must be located in such a position that it can neither become

overheated nor contact moving parts

• All wiring must be protected from chafing

• An earth return wire must be provided between the trailer and its hauling

vehicle; it is not acceptable to use the trailer coupling as an earth.

AUSTRALIAN TRANSPORT SAFETY BUREAU

(DOTARS) TECHNICAL REQUIREMENTS

Trailers and towing vehicles must have electrical connectors which comply

with Australian Standard 2513-1982 'Electrical Connectors for Trailer

Vehicles' or as amended from time to time. Three types of seven pin

connectors are specified in the Standard and their wiring is shown below.

Twelve pin connectors are also specified in the Standard.

Note: Because of interchangeability problems that may arise it is

recommended that pin 5 in the 7 pin connectors be used only for service

brakes. If auxiliary circuits are required then the 12 pin type 3 connector

would be preferable.

The Agility™ Electronic Brake Control, Part No. 47295, is a device designed to manage electric trailer brakes. It is suitable for 2, 4, or 6 trailer brake applications and operates on an inertia-activated principle, meaning it will not automatically apply trailer brakes when the vehicle is stationary unless the vertical slide is depressed. The unit is not reverse polarity protected, so incorrect connection to the vehicle or breakaway battery can damage it.

Technical Specifications and Features:

Braking Capacity: Supports 2, 4, or 6 trailer brake applications.
Inertia Activation: Applies trailer brakes based on vehicle deceleration.
Reverse Braking: The brake control will apply trailer brakes while the vehicle is in reverse.
Mounting Angle: Can be mounted from -20 degrees nose down to +70 degrees nose up, parallel to the direction of travel.
Display: Features a digital readout display (B) to show power settings and indicate trailer connection or short circuit.
Manual Override: Equipped with a vertical slide (A) for manual brake application.
Sensitivity Adjustment: A button (C) allows adjustment of the trailer braking response from least sensitive (setting 1) to most sensitive (setting 5).
Digital Power Setting: Buttons (D) adjust the power sent to the trailer brakes, displayed as a percentage from 5% to 99% in 5% increments.
Short Circuit Indication: The display will show "SC" if a short circuit occurs.
Compatibility: Designed for electric trailer brakes only, not electric-hydraulic brake systems.
RF Interference: Should not be mounted or activated near RF-generating devices (e.g., mobile phones, two-way radios) within 40cm proximity.

Installation Guide:

Mounting: Secure the provided bracket using Phillips screws (A) in a location where the display is visible and the vertical slide is easily accessible.
Attachment: Attach the brake control to the bracket using the slotted hex screws (B).
