I remember running into this Fritzing part when I was trying to help a friend of mine making his first Arduino project and wanted to provide him a breadboard layout. It was ridiculously difficult to modify that part in Fritzing. After that I wanted nothing more to do with the program.
I believe the reason for the part being that way is the PIR module Adafruit sells happens to have the opposite pinout from all the common cheap PIR modules you find everywhere else:
I seem to remember that Fritzing part was made by Adafruit.
To make things worse, some of the modules (like the one BeastHunter is using) have the pinout marked on the side of the PCB that's covered by the diffuser!
