# Install DataLogger on a light-duty vehicle

> Step-by-step instructions for plugging the DataLogger device into the OBDII port of a Class 1–3 light-duty vehicle, model years 1996 and newer.

# Install DataLogger on a light-duty vehicle

**Step 3 of 6 — Install on a light-duty vehicle (Class 1–3)**

Plug the DataLogger directly into the 16-pin OBDII port on your Class 1–3 vehicle. No cables or tools are required for the standard installation.

## Before you start

* Confirm your vehicle is a **Class 1–3 light-duty vehicle** from model year 1996 or newer. Vehicles in this range have a 16-pin OBDII port.
* Have the DataLogger device from your shipment ready.
* The vehicle must be turned off before you begin.
* If you have not yet received and inspected your shipment, complete [Receive and inspect your device shipment](/gps-tracking/device-setup/receive-and-inspect-your-device-shipment) first.

## Steps

1. **Turn the vehicle off.**
2. **Locate the OBDII port.** On most light-duty vehicles, the port is on the driver side of the vehicle in the footwell, underneath the steering column trim. While the exact location is not standardized, most manufacturers place it in this area.
3. **Firmly install the device into the OBDII port.** Press it in until it seats fully.
4. **Turn the vehicle on and check the LED indicators.** The LEDs should illuminate, confirming the device is receiving power. Note: LEDs may extinguish after a period of time — this is normal behavior.
5. **Secure the device.** Because the OBDII port is typically in an unobtrusive location, the device usually does not require additional fastening. If the device protrudes in a way that could cause interference with pedal operation, use zip ties, double-sided tape, or Velcro to tuck the device out of the way behind vehicle paneling.
6. Ensure the device is secured so it remains stationary and cannot move freely — movement can cause rattling or connector wear.

## Extension and Y-cable situations

* **Extension cable:** In rare cases where the OBDII port is in an inconvenient location, an extension cable can relocate the device to a better position. Contact Servinix support to request an extension cable.
* **Y-cable:** If the device must be hidden from view while keeping the OBDII port accessible for other tools, a Y-cable is required. Contact Servinix support if this configuration is needed.

## Result / verify

The device LEDs illuminate (or illuminate briefly) after plugging in, confirming it has power. Proceed to [Verify device connection](/gps-tracking/device-setup/verify-device-connection) to confirm data is flowing to Servinix.

## Troubleshooting

* **LEDs do not illuminate at all:** Confirm the device is firmly seated in the port. Try unplugging and re-seating. If LEDs still do not light, see [Device LEDs off after install](/gps-tracking/gps-troubleshooting/device-leds-off-after-install).
* **Device causes driver interference:** Reposition using an extension cable. Contact Servinix support to obtain one.
