Looks like they may have left you some spots to put two more diodes for a full bridge. If everything exists as the graphics show then wiring the 12V transformer winding from either 12 to the 0 connnection will get you running half wave. You should inspect those traces around the empty pads and determine how to install the additional diodes and wire for full bridge.

The manufacturer should have made up their minds and either sent you a center tapped transformer or a complete rectifier circuit.
