Level of Difficulty
Easy
WARNING
Never exceed the vehicle manufacturer's recommended towing capacity.
In order to avoid severe damage to the tow vehicle's electric brake controller, disconnect
the trailer connector from the tow vehicle prior to testing the breakaway system.
CAUTION
Do not attach the breakaway switch cable to
mounting hooks, trailer safety chains or the trailer ball.
Maintenance
Prior to each use, check the system's battery for operating voltage. Check that the breakaway
switch cables are not damaged from dragging on the ground and that they can move freely.
Check the breakaway system periodically to ensure proper and secure connections.
Open and / or short circuits may result in a no-brake situation.
Test the breakaway by pulling firmly on the cable of the
breakaway switch. The battery will activate the brakes.
NOTICE
Before you begin installation, read all instructions thoroughly.
Proper tools will improve the quality of installation and reduce the time required.
To help prevent damage to the product or vehicle, refer to the specified
torque specifications when securing hardware during the installation process.

Functionality and Application
The breakaway kit uses a battery to engage
the trailer’s electric brakes if the trailer
becomes disconnected from the tow vehicle
while driving. The breakaway kit includes a
push-to-test battery testing system to allow
the charge level of the breakaway kit’s
battery to be verified before each use.
The breakaway battery when fully charged
will provide enough power to stop the
trailer and allow for time to add wheel
chocks to the wheels of the trailer in
the event of a breakaway situation.
Note: The trailer will not be held by
the breakaway kit indefinitely. Do not
use this kit as a trailer parking brake.
This breakaway kit is designed only for
one or two axle trailers installed with
electrical trailer brakes. Breakaway
kits are generally required with a trailer
of 3000 lbs. GTW or greater. Check your
local laws for specific requirements.
The built-in battery charging system will
recharge and maintain the breakaway
battery’s charge when the trailer’s 7-way
electrical connector is connected to a
running vehicle. The test button provides
an easy to read test of the state of
charge of the breakaway battery.
