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, and 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 de-
vices is the unexpected disconnection of the power or ground wires.

1) Connecting Constant +12V Power (Red wire)

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 RED
wire from the tracker to the source of
+12V. Be sure not to permanently disconnect the 12V source to other circuits in the ve-
hicle 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 an-
other 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 MTM1000 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 ap-
plications the white wire can be used for ignition sense.
