Skill level: Intermediate

Installers must be able to remove dash panels and instrument clusters, and mount and secure devices safely.

This guide explains how to install a Vehicle Data Device using an extension cable.

Time required: 10 to 20 mins

The engine must be OFF when installing the Vehicle Data Device.

Once the device is installed, wait 10 mins before starting the vehicle.

An extension cable allows you to install the device away from the OBD-II port.

If you are installing a road-facing camera in the same vehicle, you can use the extension cable with the OBD-II passthrough from the camera kit to keep your OBD-II diagnostics port available.


Step 1. Check the box contents


  • Vehicle Data Device (VDD)
  • 31" OBD-II extension cable
  • 8" zip ties (x2)
  • 14" zip ties (x2)

Step 2: Identify the parts of the extension cable

Parts_of_the_extension_cable.pngThe cable consists of the following parts:

    • (A)Connector that plugs into the vehicle's OBD-II port
    • (B)Fuse holder with replaceable fuse
    • (C)Device connector for the VDD

Step 3. Record device and vehicle information

Record the device IMEI and the vehicle it's being installed into before continuing. You need this later to verify the installation.
The IMEI can be found on the back of the device or on the box.

Step 4. Locate OBD-II port


  1. Move the vehicle to an area with good network coverage.
  2. Make sure your vehicle is turned off.
  3. Locate your vehicle's OBD-II port.
    The port is usually located under the dashboard or beneath the steering wheel column. If not located beneath the steering column, look for the port in the areas indicated in the image.
    For help finding the OBD-II port, read Find the OBD-II port.

Step 5. Plug cable into the vehicle's OBD-II port Plug_cable_into_OBD_port.png

  1. Plug connector A into the vehicle's OBD-II port.
    Take care if you are removing the dash panel. Improper removal can cause damage. If you are not familiar with removing these panels, consult someone who has such experience.
  2. Route the cable under the dash to where you intend to secure the device.

Step 6. Connect the OBD-II passthrough (Optional)

  1. If you're installing a road-facing camera with the extension cable after the Vehicle Data Device, connect the OBD-II passthrough from the camera kit to the cable's device connector (C).


Step 7 . Plug the Vehicle Data Device into the cable Plug_device_into_cable.png

  1. With the engine off, plug the Vehicle Data Device into the cable's device connector (C) or the OBD-II passthrough if you're also installing a road-facing camera.
  2. Listen for a beep sound. A single beep indicates your device is plugged in correctly and receiving power.
    Didn't hear the beep?

Step 8. Mount and secure the Vehicle Data Device

Before you mount and secure the device:

  • Do not mount the device directly under metal surfaces as this can block the network and GPS signal.
  • Do not mount the device near a source of heat such as a heating vent or duct. This can damage the device and melt the cable.
  • You must secure the device firmly so it cannot move around. If the device is not secure, it will impact the accuracy of harsh driving events.
  • You must coil up and secure the cable so that it does not get in the driver's way.

If you are installing a camera with the extension cable, wait until after you have installed the camera to mount the Vehicle Data Device.

To mount and secure the device:

  1. Look for a stable mounting location under the dashboard, such as a wire bundle or bracket.

  2. Secure the device to the vehicle with zip ties.

  3. Tidy up the cable and secure it with zip ties.
  4. Check everything is fastened tightly and cut off excess length of zip ties if needed.
    WAIT 10 MINUTES BEFORE SWITCHING THE ENGINE ON. This gives the Vehicle Data Device time to download the latest updates.
