The cover has holes in the bottom plate to secure it on something. I made 2 versions, one where all the cables go trough a hole in the back and one that uses aviation type connectors. The one that uses aviation type connectors has labels on the back and side above the connectors for the sensor, fan and power. The spacers are used to get the right position for the display and menu leds. To secure the module you will need 4 long M3 bolts with nuts. To mount the bottom to the cover you will need to tap the holes with M3.
