Just collected my D10 Housing and the Subal distributor (Sea Optics) in Australia has set mine up for DTTL on the left socket and manual for the right socket.
The D10 sockets are wired to a pcb that has four sockets the two outside are for manual mode (3 wire) and the inside connector sockets (5 wire) are for DTTL connections. Just change the pcb connections depending on what type of strobes you are using - no messing around with soldering or blocking off pins etc.
