Fiat part number: 5911213
Remote locking relay and two remotes.
Only remote locking, no connection to turn signal lights (had to make my own).
Still got the original box as I keep the original central locking relay there.
Installing aftermarket kit is easy as there are just two wires you need to connect in addition to power and ground assumig you have central locking.
Connect one to ground, locks the doors, ground the other one, unlocks them.
