4 pin is pin 1 is gnd, pin 4 is +12V
BTW there is a weird 4 pin configuration with 3 in a triangle and 1 pin 
in the middle.  I've seen it in a catalog, but never in the wild.


The 5 pin XLR is used for DMX lighting controllers, so you want to 
either be compatible pinout (i.e. not blow things up) or avoid it. Pin 1 
is ground, don't recall how the rest is laid out, other than it's a pair

The 6 pin XLR is a bit unusual, and the pins are significantly smaller, too.
