AT-3000

Before You Begin

The installation kit contains a registration card, the AT-3000 device, eight 8″ zip ties, two 14″ zip ties, one star washer, one self-tapping screw, two heat shrink butt connectors, one ring terminal and two inline fuse holders with 3 amp ATC fuses. Additional tools and supplies that you will need include a digital multimeter, a crimping tool, a razor knife, wire strippers, plastic cable ties, electrical tape, tamper seal compound and self-tapping screws.

Complete the registration card by locating the serial number of the device (labeled “ESN” or “SN”) and copying it onto the card. When the card is complete, you’re ready to start the installation.

The 3 Amp fuses included in your kit are rated for 12-14.5 VDC electrical systems. Adjust the fuse rating according to the rating of your electrical system.

Installation Overview

The following steps provide an overview of the installation process:

  1. Determine the mounting location.
  2. Locate wires with proper voltage for constant power, ignition detection, and ground wires.
  3. Mount the GPS device.
  4. Connect the constant, ignition detection, and ground wires.
  5. – INSTALL OPTIONAL ADD-ONS –

  6. Tape the harness wires.
  7. Verify installation, and tamper-proof remaining connections.

Installation Steps


  1. 1. Determine device mounting location.

    1. The AT-3000 is designed to be mounted on the outside of the asset. Choose a proper installation location, preferably one that is on a level section on top of the asset.

    2. Check the underside of this location to make sure there are no hoses or wires that may be damaged by mounting the hardware.
    3. Remove any panels that provide access to this area, and confirm routing of the wires to the constant power and ignition source is possible.

  2. 2. Locate wires with proper voltage for constant and ignition detection.

    1. With the ignition off and the key removed, use a digital multimeter to locate a wire that is consistently receiving between 12-24 VDC (+); this wire will be the constant power source.
    2. If the asset is equipped with a master battery cut-off switch, wire around this switch and go directly to the asset’s battery for constant power.

    3. Identify a wire that supplies between 12-24 VDC (+) when the key is in the Ignition On position but 0 VDC (+) when the key is in the Off or Accessory position; this wire will be the ignition source.
    4. Red = Constant 12-24 VDC (+). White = Ignition detection 12-24 VDC (+) with Ignition On, 0 VDC (+) with the Ignition Off or in Accessory. Black = Ground 12-24 VDC (-).

  3. 3. Mount the GPS device.

    1. At the top of the asset, and within three inches of where you will mount the device, drill a hole for the harness to slip through, and install a rubber grommet if necessary.
    2. Slide the harness through the hole, route the wires to your predetermined connection locations, and then screw using the two mounting brackets, securing the device to the asset.mounting-device

  4. 4. Connect the constant, ignition detection, and ground wires.

    1. Locate the wire you’ve isolated as the constant power supply, and remove an inch of insulation of the wire with a razor knife and wire strippers.
    2. Poke through the exposed wire to create a loop.

    3. From the device harness, locate the RED constant power wire, and strip off about 1 1/2 inches of the insulation from the end of the wire.
    4. Twist the ends, and poke it through the loop that you just created. Squeeze the loop shut, and wrap the bare wire around the loop at least 3 times. Fold the RED wire back over the loops, and then wrap the connection in electrical tape. Use two plastic cable ties, one directly over the wire-to-wire connection, and one to secure the stress loop about 2.5 cm/1″ away.

    5. Snip off the end of the zip tie, and create a stress loop with the attached wire. Apply a zip tie to secure the stress loop with the vehicle’s wire, and then snip off the end of the zip tie.

    6. Repeat this poke-and-wrap / stress-loop technique for connecting the device harness WHITE ignition detection wire to the wire you’ve isolated as the ignition source.
    7. Use heat shrink crimp connectors to protect these connections if they are not located inside the cab or inside of a control box.

    8. Crimp a ring terminal to the end of the BLACK ground wire, and secure it to the vehicle’s chassis using a self-tapping screw and star washer (internal/external locking washer). Do NOT ground to dash metal.

  5. 5. Tape harness wires.

    1. Tape off all unused harness wires using electrical tape.

    2. Upon successful connection, observe the GPS and Cellular lights on the device. Both lights will begin to blink slowly as the device powers on and will begin to blink faster as it searches for signal. A solid amber light indicates that it has received a cellular lock, and a solid green light indicates it has acquired a GPS lock.

      If the installation is taking place in an area with limited view of the sky, the device may not reach full signal until the asset has been placed outside of that location.

  6. 6. Verify installation, and tamper-proof remaining connections.

    1. Do not start the asset.
    2. To activate and register your device, with your vehicle card in hand, call 866-477-4321 option 2 or use the GPS Insight Verification App via smart phone (iOS | Android).
    3. After the installation has been verified, apply tamper seal compound to all connections.
    4. Coil and zip-tie any excess wires to the asset’s existing wiring.
    5. Reassemble any panels, and then give the registration card to your GPS administrator.
