You will need two M5x12 mm screws with nuts to mount it above the X motor and two M3 screws with nuts to connect it with the drag chain (link below).
The other thing is that it will relief to the cable and connector leading to the X axis motor - you can use one plastic cable tie - as can be seen on the picture.
