It's not a silly question at all.  The way it was explained to me:

1  negative; ground 12VDC
2  pilotone/rangertone
3  remote start - bypasses switch on camera body
4  positive  12VDC

Why 1 & 4 for power?  Farthest away from each other in the connector, thus
least likely to short when it's abused (and it will be!).  Note the cute
"clues":

1 is a - or negative sign turned on its side/end
4 is a ... well, if you look reeeeeeeeeeeeeeally hard, you'll see a + in the
very shape of the number itself.

And Lael's right on:  ya don't want to never, EVER connect your 4-pin to a
3-pin.  If it's audio, you can mess things up real good; if it's 3-pin
power, THAT has become the standard for 24V, and you don't want no 24V on
your 12V control circuitry.  Odds are you may even burn out some brushes on
a stupid 12VDC brush motor.

This DOES happen if you put 12V onto the old Arri governor-controlled 9VDC
motor for the 16S/ST/M ...

Best to all
