About the extension cable

Parts of the extension cable.png

The 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

Installation steps

1. 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.

2. Plug extension cable into OBD-II port

  1. Plug the end of the cable that has pins 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.

3. Plug the Vehicle Data Device into the extension cable

  1. Plug the device into the other end of the cable.

  2. Listen for a beep sound. A single beep indicates your device is plugged in correctly and receiving power.
    Didn’t hear the beep?

4. Mount the Vehicle Data Device

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

    Avoid mounting the device directly under metal surfaces as this can block the network signal.

  2. Secure the device to the vehicle with zip ties.
    Ensure that the device does not dangle or move around. This will cause inaccurate reporting of harsh driving or crash events.

  3. Coil up the cable and secure it safely underneath the dash using zip ties.
    Ensure that the placement of the cable does not interfere with the driver's operation of the vehicle or with any vehicle controls (such as brakes and pedals).

  4. Check everything is fastened tightly and cut off excess length if needed.
    Use extreme caution when trimming the zip ties. Accidentally cutting or nicking nearby vehicle wires will cause performance issues with the vehicle.

  5. Return to the Install the VDD with the extension cable screen and tap SKIP TO CONNECT VEHICLE.
