This is a Ferrari Battery Charger / Conditioner / Tender adapter cable. It will work with Ctek Branded Chargers and uses the Ctek comfort connector. 
This was the standard charge connector used by Ferrari up to the later magnetic type, which was fitted from the 2015 California T onwards. (I also offer this later magnetic connector adapter in my listings) .
Models Include 360 / 430 / 456 / 458 / California / 550 / 599 / 612 / F12 / and many many others too.
 
This cable will also bring on the in dash charge indicator status when its charging, exactly as the original Ferrari charger does as its identical in all ways to the Ferrari original.
 
With this adapter you will no longer need to buy the official Ferrari Branded Ctek Charger from the options list. You can now connect via any Ctek charger that you choose to purchase or perhaps may already have in your possession.
