Vehicle Wiring Diagram
For CalAmp LMU2600 GPS units – Basic Install – Power Only
PLEASE READ THE NOTES BELOW – These instructions need to be followed correctly or the system will not function as designed.(If you are unsure how to install this system please hire a professional GPS installer to do this. An installer that is familiar with GPS installation will understand these instructions and will know the correct way to install the device. Davisware works with professional installers and will recommend one to you. Thanks) This is a general reference as to how the unit should be wired to allow for proper function of the software. The wiring can be routed in any manner that is safe and will provide the correct power and function to the unit.
- It is recommended that all fuses be used as shown.
- Don’t push a test probe in the 20 pin connector, this will spread the connector and cause the wire harness to intermittantly connect to the unit. This will cause intermittant problems with function.
- All wire connections to the vehicle should be secured with solder or with a positive crimp on connector. Just wrapping the wires together is NOT ACCEPTABLE. This will cause intermittant functionality issues.
- Any questions, please contact Davis Business Solutions at 847-426-6000.
Unit Installation
The GPS should be mounted as high up under the dash as possible but keeping it away from metal surfaces and not in
an area where the unit will be over heated by the sun. The units should not be heated by the sun!!! This means it
should not be mounted on the dash and it should not be placed under the plastic dashboard. It also should not be
placed near the heat ducts in the vehicle.
GPS Unit and LED Explanation below
Notes:
- GPS Staus (Green LED) should stay on solid at all times when the ignition is ON with the main power connected
and the GPS has a fix. This light will blink slow on power on and blink fast when it has a time sync. The normal
condition is when the light is on solid. On solid means the GPS has a GPS fix and is ready to track. This light will
be off when the unit is off and in sleep mode.
- Cell Signal (Orange LED) should stay on solid at all times when the ignition is ON with the main power connected
and the unit is registered on the cell service. This LED will blink slowly when searching for cell signal, it will blink
fast when a cell service is available and attempting to connect. The LED will also blink 4 times and pause when
the unit is registered but has not received an acknowledgement from the service. This light will be off when the
unit is off and in sleep mode.

Black – Ground
Red – Constant Power (12v wired to battery or tapping to another wire with constant power at ALL TIMES)
White – Ignition Circuit (12v ONLY when the vehicle is ON. 0v while vehicle is off)
When the device is showing towing events, is telling us that the RED and BLACK wires are correctly installed. But the device does not know that the ignition has been turned on. The white wire is how we know the ignition status.
This type of issue can be caused by the following:
- The white wire is not connected or loose enough where there is no contact. - The white wire is connected to the same source as the black wire. Which means there is no voltage and the device believes that the ignition is never on. - The White wire could be incorrectly connected to a ground wire or a circuit that receives no voltage when the ignition turns on.
You can test the “HOT” Side by using a voltmeter on the ignition circuit. Test each side. You should have 12v when ignition is on and 0v when the ignition is off.
Power (Red Wire) The red wire must be connected to a constant power source. Proper wiring will ensure you receive accurate reporting’s within the GPS Tracker application. Incorrect wiring of the red wire can cause the unit to show incorrect power up events. Good sources are (Battery, Alarm System, and Clock).
Ground (Black Wire) A good ground connection is vital for proper CalAmp performance. When wiring the black (Ground) wire from the harness, look for a bolt, screw, or wire that contacts the bare metal of your vehicle’s chassis. Loosen the bolt, slip the ground wire underneath, and then tighten the bolt. If your ground wire doesn’t contact bare metal, your CalAmp won’t operate. A loose or weak ground connection can result in inconsistent readings from your CalAmp.
Ignition (White Wire) A switched power source is only on when the ignition is keyed — connect your white harness cable to a switched power source, so that the CalAmp performs the Ignition Off when you turn off the car, and Ignition On when the vehicle is powered on. Good sources are (Ignition Switch in fuse box, fuel pump)
