SPR-RELAYKIT is an accessory for IOX-NFCREADERA, IOX-OUTPUTM, and IOX-KEYLESS. It provides added features to remotely enabled vehicle functions (vehicle immobilization, activating a 3rd party product, functioning a vehicle feature remotely) from the Fleet Management Application.

The kit contents are pictured in the accompanying images.

! IMPORTANT: Due to the complexity of applications, on a wide variety of specialized uses and vehicles, we do not provide comprehensive support for all uses and installations.

✱ NOTE: Always fuse your connections.

✱ NOTE: Support can only be provided for the functioning of the Telematics Device and relay, and only used with the GO6 or newer device.

WARNING! This product cannot be used for push button start vehicles.

WARNING! Integration of this product into vehicle systems requires professional installation by a licensed automotive electrician and/or mechanic who is also Certified Geotab® Advanced Installer or equivalent.

WARNING! This product is not designed for use in a fail-safe manner. Using the product in a fail-safe manner may result in loss of vehicle control, accident, and/or serious injury. Do not install a circuit interrupt on any circuit that may interfere with the safe operation of a vehicle, or cause the engine to stop while the vehicle is in motion. Incorrect installation can cause unexpected loss of engine power, fuel, or other critical vehicle systems, leading to loss of vehicle control, accidents, serious injury, or death.

Installation Instructions

WARNING! Always read and follow all safety information, including Important Safety Information and Limitations of Use, before harness and/or IOX installation. Disconnect the GO device from the vehicle before installation and connect it post-installation. Failure to follow these instructions and warnings can result in loss of vehicle control and serious injury or vehicle damage.

GO6 and newer devices

When the IOX-NFCREADERA is used to control the SPR-RELAY KIT, connect and fuse the YELLOW wire from the SPR-IOXREL to the vehicle ignition. Then, insert the BLACK connector into the IOX-NFCREADERA (as shown in the SPR-IOXREL to IOX-NFCREADERA figure).

The SPR-RELAYKIT circuit interrupt is performed using pins 30 and 87a (standard SPDT relay). This means that the relay is a closed circuit when at rest, and the connection only opens when activated.


Relay Harness



When the IOX-OUTPUTM is used to control the SPR-RELAYKIT, follow these steps:


Connect and fuse the YELLOW wire from the SPR-IOXREL to the vehicle ignition.


Cut the BLACK connector from the BLACK wire on the SPR-IOXREL, and cut the BLACK connector from the WHITE wire of the IOX-OUTPUTM.


Connect these two wires (WHITE to BLACK) together using solder and/or heat shrink, or a butt connector.


Relay Harness

Choosing the right relay

The SPR-RELAYKIT contains both a 12V and a 24V relay.

Please ensure you select and install the correct relay for your vehicle based on the specific voltage indicated on the back of the relays.

Settings in the Fleet Management Application

Prior to the installation, enable the relay option as well as the option to control the relay remotely for the asset in the Fleet Management Application.

Enabling the relay option for the asset

To enable the relay option in the Fleet Management Application, follow these steps:


Navigate to the database in the Fleet Management Application where the device is registered.


Select Vehicles & Assets from the main menu..


Select your asset.


✱ NOTE: Toggle on Enable audio feedback under the Audio feedback tab to complete this step, if applicable.

Under the Audio feedback tab, toggle on the Driver identification reminder option.


Select Save.

NOTE: The relay does not function if this feature is toggled off.

Enabling the option to control the relay remotely

To control the relay remotely, or to use a Driver ID key to control the relay, follow these steps:


Select Vehicles & Assets from the main menu.


Select your asset.


Under the Settings tab, select IOX & Auxiliaries.


For Driver ID relay, choose one of the three options:

  1. Turn Driver ID relay on — Activates the Driver ID Relay and overrides a Driver’s ID key.
  2. Turn Driver ID relay off — Disables the Driver ID Relay and overrides a Driver’s ID key.
  3. Use driver key to control Driver ID relay — Resets the Driver ID Relay settings to the default values. The External Relay is controlled by the Driver’s ID key, if the Driver identification reminder is enabled under the Driver Feedback tab.
  4. NOTE: These settings immediately take effect if the vehicle is currently connected to the service. Otherwise, the setting takes effect the next time the vehicle communicates with the service.

    NOTE: The Driver ID Reminder feature will only work when the Use driver key to control Driver ID relay option is selected.


Select Save.

Important Safety Information and Limitations of Use

For the latest version of Limitations of Use, please visit:

WARNING! Do not attempt to install, configure or remove any product from any vehicle while the vehicle is in motion or otherwise in operation. All installation, configuration or removal must be done only in stationary vehicles which are securely parked. Attempting to service units while being operated could result in malfunctions or accidents, leading to death or serious personal injury.

WARNING! All in-vehicle devices and related cabling must be securely fastened and kept clear of all vehicle controls, including gas, brake and clutch pedals. You must inspect devices and cabling on a regular basis to ensure all devices and cabling continue to be securely attached. Loose cabling or devices may impede the use of vehicle controls, resulting in unanticipated acceleration, braking or other loss of vehicle control, which could lead to death or serious personal injury. Improperly fastened in-vehicle devices may detach and impact operators upon sudden acceleration or deceleration, which may cause injury.

WARNING! If at any point after an in-vehicle device is installed a warning light illuminates on the vehicle dash or the vehicle stalls or has a marked drop in performance, shut off the engine, remove the device, and contact your reseller. Continuing to operate a vehicle with these symptoms can cause loss of vehicle control, and serious injury.

WARNING! Your in-vehicle devices must be kept clear of debris, water and other environmental contaminants. Failure to do so may result in units malfunctioning or short-circuiting that can lead to a fire hazard or vehicle damage or serious injury.

WARNING! Do not attempt to remove the devices from the vehicle in which they are originally installed for installation in another vehicle. Not all vehicles share compatibility, and doing so may result in unexpected interactions with your vehicle, including sudden loss of power or shutdown of the vehicle’s engine while in operation or cause your vehicle to operate poorly or erratically and cause death or serious injury and/or vehicle damage.

NOTICE: This product does not contain any user-serviceable parts. Configuration, servicing, and repairs must only be made by an authorized reseller or installer. Unauthorized servicing of these products will void your product warranty.
