Connect to OBD-II port using the Y-cable

Follow the instructions to properly install the device with a Y-cable.

About the Y-cable kit


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:

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. Unmount the vehicle’s OBD-II port

  1. Unmount the OBD-II port from its mounting location by either pushing it through towards the floor or unscrewing the mounting bolts or screws.
    You might need to remove the dash panel to remove the OBD-II port. Improper removal can damage your vehicle. If you are unfamiliar with either of these processes, consult with someone with experience.
    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.

3. Attach core connector to mounting adapter

  1. Find the mounting adaptor that most 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.

4. Plug cable into core connector

  1. Plug the cable’s replacement OBD-II connector into the back of the core connector.
    You have now assembled the replacement OBD-II port.
    Warning: Use extreme caution when attaching the cable to the core connector. Make sure that you do not bend or break the core connector pins as this can cause performance issues with the vehicle.

5. Mount replacement OBD-II port

  1. Mount the replacement OBD-II port you have assembled into the vehicle’s original OBD-II port location.
    • If the original OBD-II port was pushed through from the front, push the replacement OBD-II port from behind.
    • If the original OBD-II port was unscrewed, use the same screws to mount the replacement OBD-II port.

6. Plug original port into bypass connector

  1. Plug the vehicle’s original OBD-II port into the cable’s bypass connector.
    Warning: Use extreme caution when attaching the bypass connector to  the vehicle's original OBD-II port. Putting stress on the wires or otherwise damaging the port can cause performance issues with the vehicle.
  2. We recommend securing the port to the bypass connector with a zip tie.

7. Plug the Vehicle Data Device into the cable

  1. Plug the Vehicle Data Device into the cable’s device connector. (It is the connector without pins.)
  2. Listen for a beep sound.
    Note: A single beep indicates your device is plugged in correctly and receiving power.
    Didn’t hear the beep?

8. Mount the Vehicle Data Device

  1. Look for a stable mounting location under the dashboard, such as a wire bundle or bracket.
    Note: 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.
    Note:To prevent inaccurate reporting, ensure the device can’t move around.
  3. Tidy up the cable and secure it with zip ties.
    Note: Ensure the cable does not get in the driver's way.
  4. Check everything is fastened tightly and cut off excess length if needed.
    Note: If you have removed the dash panel, do not replace it until the network connection is confirmed in the following steps.

9. Return to the app


  1. In the app, tap SKIP TO CONNECT VEHICLE.

Connect vehicle to Verizon Connect
