GPS Tracker Installation Guide


This installation guide is intended for agencies who have purchased GPS trackers directly from Swiftly. 

For any questions about GPS trackers or installation, contact:

The basics

  • GPS trackers function by using a vehicle’s power supply via wires found just below the dashboard. Each tracker has a built-in backup battery that will activate if the power supply is cut off (e.g. when the vehicle is turned off).
  • Installed trackers only use vehicles for electrical power, and do not interfere with diagnostics testing or interlock systems.
  • Trackers must have a minimum of 12 volts for full functionality.
  • Trackers should be installed by an experienced professional maintenance person or vehicle electrician.
  • Installation takes 10-15 minutes per vehicle
  • Additional materials you will need:
    • Zipties
    • Velcro or double-sided tape
    • Electrical tape
    • Wire cutters

Identifying tracker ESNs

The tracker log will contain the ESNs of the GPS trackers we’ve sent you – these are the identifying numbers of the trackers. The ESN number of the tracker can be found in the middle-right region of the tracker’s label:




Trackers will arrive to you fully configured and equipped with all required accessories. When your maintenance crew is ready to install the GPS Devices, please refer below for best practices.

Very Important: During installation, keep track of which vehicles trackers were installed onto by filling out the online GPS Tracker Log provided to you. If you're unsure of where this GPS Tracker Log is located, ask your Customer Success Manager or email






1. Connect the tracker to power

Connecting trackers via hardwire connection will require an electrician or mechanic, but is a fairly simple task altogether. Ground and power wires are located beneath the driver-side dashboard.


Installation tips:

  • We recommend connecting the wires of the power harness using the poke-and-wrap method; this provides the most secure connection and is less likely to disconnect unexpectedly. Here’s an online video explaining the poke-and-wrap technique.
  • We recommend using a zip tie to keep the fuses sealed and together. This prevents any tampering with the devices.



2. Place and secure tracker

Trackers can be stored under where the vehicle’s electrical wires are located. It may be helpful to secure the tracker using a double-sided tape or Velcro:


If trackers are kept inside designated electronics boxes, make sure the external antenna is placed in a high and upward place outside of this box; these electronic boxes have been found to cut off cell service and GPS signal.

3. Connect to external antenna

The provided antennas are intended for window mounting. Connect the GPS (SMA) and GSM/Cellular (SMC) cords of your existing antenna to the external ports on the tracker.

Some antennas may have an SMA-to-SMC converter for the GSM/Cellular port. Make sure that this converter is screwed on tightly.



Place the adhesive side of the antenna facing in an upward direction, such as on the windshield, or any high location with visible access to the sky:



Installation tips:

  • We recommend placing the antenna in the top left corner of the windshield
    • This positions the antenna toward the center of the roadway, which is the furthest place from tall buildings that may affect GPS quality,
  • The external antenna wires can be run through the nearest windshield column to secure and hide loose wires.


4. Verify tracker is operational

Once the tracker has been hardwired and the external antenna plugged in and mounted, the diagnostic LEDs should light up. The tracker may take a few minutes to begin reporting its location successfully.

After installing the tracker, monitor the LEDs to make sure they light up in the correct pattern: the green light should remain steadily lit, while the orange light should blink in a pattern of three short, one long blink. Other patterns may indicate problems; if an irregular pattern persists longer than 15 minutes after plugging in the tracker, please alert us.

A successfully configured and working tracker’s LEDs should flash like so:  



5. Log the installation!

This is mentioned twice in this guide due to its importance. As mentioned above, please remember to log the installation using the online GPS Tracker Log that was shared with you. Skipping this step can cause a great deal of time and energy wasted!


Diagnostics & Troubleshooting

For troubleshooting tips, take a look at our Help Center articles for GPS Trackers here.   

All GPS trackers have diagnostics LEDs that indicate the certain operational behavior. See below for translations of LED colors and patterns:



Is there a minimum distance that I should respect between the device that controls the doors and the tracker?

There shouldn't be an issue with the device that controls the doors since we use an external antenna which will be placed a ways away from the door. Therefore there shouldn't be any electrical interference.


Can I place the antenna in the rear windshield of the vehicle?

Ideally the antenna would be located where the front door is so that we are really recording when the bus gets to a bus stop. But the rear of the bus is only about 13 meters back, so the difference is inconsequential.


How difficult is to install a tracker into a vehicle?

The device installation is a very basic task for a vehicle mechanic or maintenance person. It usually takes 10 - 15 minutes per vehicle.
