I can tell you that the Shure 520D is an exception to the rule above. 
At least the one I got - the element (made in Mex. controlled magnetic) 
has 3 wires - blue, red, black. They were wired to the built in cable, 
red to red, black to shield, and blue to black. The guy I bought it 
from had someone put a connector on the cable so I don't know how the 
mic came wired from the factory. But mine came with the black wire 
soldered together with the shield at the connector ground (as suggested 
above) - output was almost non-existant. In this case, the black wire 
should be left DISCONNECTED - it is there to allow external re-wiring 
of the mic to low impedance.
