Hm... Can't find any datasheets, but can make some educated guesses... From looking at it, I'd guess that it follows the 44780 type control setup (so the LCD routines on this site would work, but need to be modified slightly for the longer width). At a glance, it looks like the pinout would be something like:

1) gnd
2) vcc
3) contrast
4) RS
5) RW
6) E
7) D0
8) D1
9) D2
10) D3
11) D4
12) D5
13) D6
14) D7
15) Backlight Anode
16) Backlight Cathode

I'm guessing this because pin 1 seems to be strapped to ground, 15 & 16 seem to go out to the sides as a backlight might, and the rest is simply that this seems to be the standard conventional pinout used by most 44780-or derivative- based modules.
