Attempting to service devices while the vehicle is in motion could result in malfunctions or collisions, leading to death or serious personal injury.

    Installing the GO device


    Locate the vehicle’s engine diagnostic port, typically found in the driver’s area at or below knee level.

    ✱ NOTE: For heavy-duty trucks, always use a vehicle-specific harness when offered by Geotab or the vehicle manufacturer (see Harness Identification and Application and Harness Assessment Cheat Sheet). Where a heavy-duty truck-specific harness is not offered by Geotab or the vehicle manufacturer, use the adapter harness (HRN-CG13S1) for any 16-pin (OBDII) installation method to avoid possible GO device damage.



    Align the receiver end of the device with the engine diagnostic port and push in place. Please ensure the device is well-connected to the diagnostic port. Once connected, the device emits 6 quick beeps.

    A user is plugging a GO device into a vehicle's engine diagnostic port.


    Once the device is connected and receives power, the LEDs on the front of the device start blinking then turn solid once completing the actions below.

    Red LED — Device configuration

    Green LED — Cellular network connectivity

    Blue LED — GPS network connectivity

    The device emits two quick beeps every 60 seconds during set-up. Initial startup may take several minutes to complete.

    The GO9B device displays red, green, and blue LED status lights.


    Once all three LEDs turn solid and you hear 10 quick beeps, secure the device using the provided cable tie.

    NOTE: The device is considered installed when the Green and Blue LEDs turn solid.
