Heh, I bought that same exact LCD a while ago. I haven't used it, but I've used a 16x2 LED bl.
Anyway, your best bet would be to chop off the hanging connector end and use an ohmmeter to confirm the traces. As long as you keep the connector on, you'll save yourself a lot of trouble. I didn't particularly enjoy soldering 16 wires from a ribbon cable onto a 8x2 pin grid. This is something you can avoid.
