Attach ribbon cable(s). Mount RPI with provided screws to the stand-offs. Insert working sd card into RPI (disassembly required to remove later!). Wire up the power harness and fan circuit (transistors and diode and resistor). Attach signal to pin 12 (GPIO18). Put circuit in control box. Attach fan (and grill if have) with M3 screws (20mm) and nuts. Attach box to back with computer screws. put python script on RPI. Then in terminal run:<br/> sudo crontab -e choose nano as editor, at the bottom add (Assuming the name is the same; replace "/path/to/script/" with where you put the python script at):<br/> @reboot /path/to/script/fanspd.py</ol></div></p></p></p>
