    • WARNING! Only use Geotab telematics devices with Geotab-approved harnesses acquired from Geotab-authorized channels. Use of non-Geotab harnesses from unauthorized channels can cause serious safety risks, including fire, and can lead to serious personal injury and/or damage to the vehicle.

    • IMPORTANT: Always use a vehicle-specific harness when offered by Geotab or the vehicle manufacturer to avoid possible damage to the GO device. Some vehicles have multiple diagnostic connectors to choose from when installing a GO device.

    • For more information on Geotab harnesses and adapters, refer to the Harness Identification and Application & Harness Assessment Cheat Sheet & Geotab Truck Solution - Harness Identification and Application

    • If a longer length is required to facilitate installation, connect a straight harness to a T-harness. Ensure that the total harness length does not exceed 2 meters (6.5 feet), because this can compromise the integrity of the data and cause issues with the vehicle’s Engine Control Unit (ECU).

    • For more details on compliance information and applicable products, contact your Authorized Reseller.

    • Some installations are not straightforward and must be completed by an Authorized Installer to ensure a secure installation.

    • Ensure you use enough cable ties to secure both the device and the harness to the vehicle. An unsecure device can result in poor electric and/or data connections, which can lead to short circuits and fires or cause malfunctions of vehicle controls that can result in serious personal injury or significant damage to the vehicle.

    • Some examples requiring professional installation from an Authorized Installer are:

    • The OBD port location is such that the device could protrude or interfere when entering or exiting the vehicle, or located where it could be inadvertently kicked or bumped during vehicle operation. The device isn't fully secured and may be able to vibrate loose or get kicked or knocked. An electrical harness or additional wiring is required.

    • Vehicle mounting modifications are required to secure the device, such as removing of panels. The OBD connector has been deformed/damaged or there is physical damage visible to the electrical wiring.

    • The device does not power on and beep six times when first installed.

    • The installer questions their ability to complete a secure installation according to these instructions.

    • Do not attempt to install, reconfigure or remove any product from a vehicle while the vehicle is in motion or otherwise in operation. Any installation, configuration, or removal must be done only in stationary vehicles that are securely parked.

  4. Before installing, record the following:

    • Before installing, record the following:

    • GO device serial number

    • Odometer reading

    • Vehicle or asset name

    • VIN (vehicle identification number)

  5. There are 3 wires which must be connected.

    • There are 3 wires which must be connected.

    • Red

    • +12/24V Constant power must be connected to a true battery source (live at all times).

    • Black

    • Must be connected to a verified ground.

    • Yellow

    • Ignition sense wire must be connected to a true ignition source.

    • +12/24V when the key is in both ON and Run positions, 0 when in Off position.

  6. Using your wire crimpers, attach the fuse holders on to the Red and Yellow wires using the included parts. The wires should come with the insulation pre stripped; ready for crimp on connectors.

    • Using your wire crimpers, attach the fuse holders on to the Red and Yellow wires using the included parts.

    • The wires should come with the insulation pre stripped; ready for crimp on connectors.

    • Crimp one of the included butt splice connectors on to the end of the Yellow wire.

    • Crimp the open end from the previous step onto one end of the Fuse holder.

    • Using a heat gun, or other heat source, heat shrink the butt splice connectors.

    • Repeat the above steps for the Red wire.

    • The remaining blunt cut end from the fuse holder will be what is connected to the vehicle.

  7. Using your wire crimpers, crimp the ring terminal on to the Black wire.

    • Using your wire crimpers, crimp the ring terminal on to the Black wire.

  8. The completed assembly should look like this.

    • The completed assembly should look like this.

    • Geotab does not recommend terminating to unknown circuits! Appropriate reference information is highly encouraged.

    • Known and publicly available publishers for automotive electrical & electronics: Fortin's Wire Color, Alldata DIY, Mitchell 1 DIY.

  10. Locate and verify a constant +12/24V Battery source. Always use a Digital Multi Meter.

    • Locate and verify a constant +12/24V Battery source.

    • Always use a Digital Multi Meter.

    • A suitable battery source will have +12/24V at all times, just like if you were to be connected directly to the battery.

    • Typical locations

    • Ignition switch.

    • Fuse and power distribution panels.

  11. Locate and verify a +12/24V Ignition source. Always use a Digital Multi Meter.

    • Locate and verify a +12/24V Ignition source.

    • Always use a Digital Multi Meter.

    • A suitable Ignition source will have +12/24V while the vehicle's key or button is set to on/run and 0V when set to off.

    • Typical locations

    • Ignition switch.

    • Fuse and power distribution panels.

  12. Connect the ring terminal to a verified ground using a self tapping screw (not included) or existing bolt.

    • Connect the ring terminal to a verified ground using a self tapping screw (not included) or existing bolt.

    • The surface may need to be prepared prior to connection.

    • The ground surface should be bare metal.

    • Remove any paint, corrosion, or other coating if present.

    • Most heavy structure in the dash area is suitable to use as a ground. Always test using a DMM.

    • Star washers and serrated head screws are recommended. (not included)

  13. Once all 3 wires (Red, Black, & Yellow) are connected to the vehicle:

    • Once all 3 wires (Red, Black, & Yellow) are connected to the vehicle:

    • Plug the fuse holder side and the device side of the HRN-XCW03K3 harness together.

    • If installing an IOX accessory please use the correct guide from here before performing the steps below.

  15. Plug Harness into the GO Device.

    • Plug Harness into the GO Device.

    • Be sure it clips in place. Due to this clip securing the connection a cable tie is not required.

  16. Turn on vehicle ignition to initiate GO device startup and initial configuration

    • Turn on vehicle ignition to initiate GO device startup and initial configuration

    • The LED light wil flash slowly during startup which typically takes 60-80 seconds.
