This board has the proper number of connections for the Giotto/Cellini Premium Version I machines and in this case does not require a wiring loom. IT WILL REQUIRE A RECONFIGURATION OF THE WIRING WHEN MOVING WIRES OVER.
This board by itself will not fit the ECM/Giotto Classic nor Cellini Classic espresso machines made by ECM without the wiring loom. These machines requires a wiring loom that is optional with the purchase. However, we are not responsible if the machine is wired incorrectly and fries this brain unit. A wiring diagram is NOT available. Therefore, we suggest that you send the machine in for repair.
