[Teltonika Installation Guides](https://support.gsfleet.io/knowledgebase/devices-hardware?hsLang=en#teltonika-installation-guides) September 17, 2026 # How to Connect the FMS Cable for FMC640/FMC650   ![](https://support.gsfleet.io/hs-fs/hubfs/image-png-Sep-17-2026-09-30-24-9701-AM.png?width=389&height=216&name=image-png-Sep-17-2026-09-30-24-9701-AM.png) The FMS cable is a standardized heavy duty vehicle FMS 12-pin connector, for connecting FMX640/650 with one plug and receiving vehicle information through CAN line and K-line, along with powering the device and getting Ignition detection. This ensures easier connection and does not violate the factory warranty. **Technical data of the cable:**     | Supported devices | FMB640/FMC640/FMM640/FM6300 | | --- | --- | | Number of pins | 12 | | Pinout | Pin12: VDC Pin1: GND Pin6: CAN H Pin9: CAN L Pin10: Ignition Pin7: K-line | | Supported protocols | FMS/K-Line | | Length | 0.9 meter |  ![](https://support.gsfleet.io/hs-fs/hubfs/image-png-Sep-17-2026-09-30-59-9869-AM.png?width=670&height=400&name=image-png-Sep-17-2026-09-30-59-9869-AM.png) **FMS Plug Location** Even though the FMS cable is standardized cable – its placement in the vehicle might differ depending on manufacturer and depending on vehicle trim level.
