Thanks for the info. Those pins are for the backlight. I think that I'll just cut the traces on the display board and add jumpers to cross the connection.
Interestign thing is that when I go to Digikey's "LCD, OLED Character and Numeric Display" section then select "LCD" and "2x16" as the format (the only 2 filters), that display you found does nto show up in the search results.
EDIT: never mind - I had to select 16x2.
