You have many choices where to connect the locater, but the main decision you'll need to make is whether you wish to connect to a source which is "hot" all the time (ie the battery), or a source which is hot only when the ignition is on and the car is running. This decision will be driven by the autonomy of the locater (how long its own internal battery will keep it alive) and whether it'll do a "clean" startup if its battery is flat, and then it is turned back on by the car being run.
Ferrari electrical systems aren't the best, and their parasitic draw (the amount of electrical consumption when the car is sitting and not running) is rather high, and tends to flatten batteries if the car isn't kept on a battery tender, or driven regularly.
If it were me, I would steer clear of connecting the locater to an "always on" source, and opt for an ignition source.
If this strategy didn't work, then I'd look at a separate, larger, battery backup for the locater, and then use the +12 ignition source in the car to keep those batteries charged.

High mileage, low compression, and missing on a few cylinders.....just like my cars.
