HOW TO HARD WIRE YOUR GPS TRACKING UNIT

Your GPS tracking device comes with a wiring harness. All electronics and antennas are
internal to the device. Tools you may use to perform the installation include: Screwdriv-
ers, Wire strippers and cutters, Crimping tool, Voltmeter. Additional materials you might
use: Connectors, Tape, Zip Ties
For basic operation, connections are required to constant Power (+12V) and to Ground
(sometimes called negative). It is very important to ensure that your installation will last
through the use of the vehicle. The environment inside a vehicle is harsh due to vibra-
tion, temperature extremes, corrosion, humidity, and unexpected events. The primary
cause of failure for vehicle tracking devices is the unexpected disconnection of the
power or ground wires
1) Connecting Constant +12V Power
First, use the multi-meter to find a source of CONSTANT +12V near the dashboard of the
car. There are multiple places where this can be found, and the locations vary between
vehicles. Some locations are more discreet than others, so plan your installation accord-
ing to your needs. You may find specific wiring details for your vehicle on the internet
to assist in locating the wires you need. For example, http://www.the12volt.com/ is one
such source.
Ensure that the wire you choose is a CONSTANT source of +12V. The multi-meter should
show approximately 12V between your source and chassis ground regardless of the
Ignition Switch position, and whether doors are open or closed, lights or other accesso-
ries are on or off, etc.
Using your preferred connector type, or solder, connect the
to the source of +12V. Be sure not to permanently disconnect the 12V source to other
circuits in the vehicle and take care to make a strong connection to survive vibration
and temperatures

2) Connecting Ground (Black wire)

The BLACK wire must be connected to a source of chassis ground. This can be either
another grounded wire, or a clean metal connection to the chassis of the vehicle. Be
sure not to permanently interrupt the ground connection to any other circuit in the
vehicle and that you have a strong and clean connection
GREEN and WHITE Wires
The cable provided with each 1400 device also has green and white wires that for most
regular installations will not be used. For starter interrupt relay installations the green
wire is used connecting the device to the relay (ref diagram below). For special applica-
tions the white wire can be used for ignition sense.

TESTING THE INSTALLATION

Test the installation by turning the vehicle on and o!, opening and closing the driver's
door, and turning lights and dome lights on and o!. Constant power should not be inter-
rupted by these actions, and the device should continue to operate as you can tell by
looking at the lights.
