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 a Y-cable.

Time required: 20 to 30 mins

The Y-cable allows you to keep the OBD-II port free for diagnostic tool scanning and to conceal the Vehicle Data Device.

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

The engine must be OFF when installing the Vehicle Data Device. Once the device is installed, wait 10 minutes before starting the vehicle.

Step 1. Check the box contents


  • Vehicle Data Device (VDD)
  • OBD-II Y-cable (approx. 9ft)
  • 8" zip ties (x4)
  • 14" zip ties (x2)
  • Mounting adaptors
  • Core connector

Step 2. Identify the parts of the Y-cable


The cable consists of the following parts:

  • (A)Cable connector
  • (B)Bypass connector that plugs into the vehicle's OBD-II port
  • (C)Fuse holder with replaceable fuse
  • (D)Device connector for the Vehicle Data Device

The cable comes with the following parts:

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. Unmount the vehicle's OBD-II port

  1. Remove the vehicle's OBD-II port from its mounting bracket by pressing the release tabs or by removing the screws that hold it in place.
    You might need to remove the dash panel to remove the OBD-II port.
    Warning:Use extreme caution when you unmount the vehicle's OBD-II port. Putting stress on the wires or otherwise damaging the port can cause performance issues with the vehicle.

Step 6. Attach core connector to mounting adapter

  1. Find the mounting adaptor (F) that matches the shape of your vehicle's OBD-II port.
    Make sure you choose the correct mounting adapter before attaching it to the core connector. Once attached, the parts are very difficult to take apart.

  2. Attach the core connector to the appropriate mounting adapter.

Step 7. Plug cable into core connector

  1. To assemble the replacement OBD-II port, plug the cable's replacement OBD-II connector (A) into the back of the core connector (E).

Step 8. Mount replacement OBD-II port

  1. Screw or snap the replacement OBD-II port into the vehicle's original OBD-II port location.

Step 9. Plug original port into bypass connector

  1. Plug the vehicle's original OBD-II port into the cable's bypass connector (B).
  2. Secure the bypass connector to the port with a zip tie.

Step 10. Connect the OBD-II passthrough (Optional)

  1. If you're installing a road-facing camera after the device, connect the OBD-II passthrough from the camera kit to the Y-cable's device connector (D).


Step 11. Plug the Vehicle Data Device into the cable

  1. With the engine off, plug the VDD into the cable's device connector (D) or the OBD-II passthrough if you're connecting 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 12. Mount 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 or interfere with the driver's operation of the vehicle.

If you are installing a road-facing camera with the Y-cable in the same vehicle wait until after you have installed the camera to mount and secure the 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.
