For the installer, step by step: three wires, two antennas, about an hour. It arrives configured - nothing to set up.
The current version, online: simple-gps.com/guide/fmm650/installer
Time
about 1 hour
Wires
3 wires + 2 antennas
Tools
Multimeter, 3 A fuse holder
Who fits it
An auto electrician
Everything your installer needs, in the order it is done. The FMM650 arrives configured and already added to your account: once it has power and its antennas, the vehicle appears on your map by itself.
Nothing to configure. The SIM, the network and our server are set before it ships. No computer, no USB cable, no app - and no need to open the case.
1
Know the device
Two antenna sockets on one edge, the power socket on the other, and two lights that show what the device is doing.
Seen from the top with the power socket at the bottom: GNSS antenna on the left, LTE on the right. The two sockets look alike.
2
The power cable
The cable plugs into the 2x10 socket and carries twenty wires. Only the three in colour are connected; every other wire stays unconnected, its end insulated on its own.
Pins 1 and 11 share a row, so the right black wire is the one beside the red. Pin 10 is black too, and pin 6 is yellow with a white stripe.
11
Red, pin 11 - power (+), 8 to 32 V
To a constant + through a 3 A fuse: a feed that stays live with the key out, best the main feed in the fuse box.
1
Black, pin 1 - ground (-)
To the chassis or a metal part bolted to it, paint scraped off. The black wire beside the red one - not pin 10, which is black too.
15
Yellow, pin 15 - ignition
To a real ignition feed: live only while the engine runs, not ACC, and it must not drop while cranking. Solid yellow - pin 6 is yellow with a white stripe.

How it connects
Three wires from the vehicle and two antennas. The fuse goes on the red wire, as close to the feed as you can.

Step by step
Check the box. The device, the GNSS antenna, the LTE antenna and the power cable. The SIM and the backup battery are already inside - leave the case closed.
Choose the places. The device goes somewhere dry and out of reach, away from heat - behind a panel or under the dashboard. The GNSS antenna needs the sky: under plastic or glass, for example on top of the dashboard under the windscreen trim, never under metal. Keep the LTE antenna away from metal too.
Fit the antennas. Screw each into its own socket - GNSS on the left, LTE on the right, as in the drawing - and route the cables without sharp bends or pinching.
Find the three feeds. With a multimeter: a constant + that is still live 30 minutes after locking the vehicle (some vehicles cut a feed 5 to 30 minutes after their computers sleep), an ignition feed that is live only with the engine running, and a clean ground point on the chassis.
Connect the three wires, cable unplugged. Red (pin 11) to the constant + through the 3 A fuse, black (pin 1) to ground, solid yellow (pin 15) to ignition. Insulate every other wire end on its own.
Plug it in. Push the connector fully into the device. Both lights start blinking.
Check it works. Outdoors, start the engine. Within a few minutes the navigation light blinks once a second (GPS found) and so does the status light. The vehicle appears on the map.
Tidy up. Fix the device so it cannot move, tie the wires to parts that do not move, keep them away from heat, and restore any insulation you opened.

Reading the lights
Navigation light
Blinking once a second: GPS works. Steady on: no satellite fix yet - go outdoors and check the GNSS antenna. Off: asleep or not running.
Status light
Blinking once a second: working. Every two seconds: asleep, normal when parked. Short fast bursts: talking to the network. Off: no power - check the fuse and the red and black wires.
!
Avoid these
Ignition from ACC. ACC is live with the key turned and the engine off, so the vehicle would look running while it stands.
Tapping into the vehicle's control units or their data lines.
The GNSS antenna under metal. It will not see the satellites.
Wiring without the 3 A fuse, or with the connector plugged in.
