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: Screwdrivers, 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 vibration, 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 Co12V Power
(Red wire)
First, use the multi-meter to find a source of CO12V 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 according 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 accessories 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 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
MTM
1000 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 applications the white wire can be used for
ignition sense.
