A few of you have asked for my K40 schematic.
I shared it at this location:

Let me know if you cannot get to it. You can access it here directly and that way you get changes or you can export and save to a .pdf.
Note: the hacks I have made to my unit are included such as the wiring for the temp display/alarm and flow switch.
