Make sure the holes fit over all the pins and then push the connector onto the pins.
Caution
If you do not correctly align the holes with the pins, you could severely damage your hard disk drive when you push in the connector.
4.Pick up the hard disk drive and hold it above the vertical mounting area so the mounting plate is facing the subassembly, as shown below.
Notice that there are two tabs facing downward on the bottom of the mounting plate. These tabs will fit into two slots in the right side of the subassembly.
