Cracked mine open, too. CH340G. No obvious way to select 5V/3.3V. Six solder pads:
Red wire to 5V (not connected on plug, guess it's snipped at that end like neilman says)
Black wire to GND
White wire to RXD
Green wire to TXD
No wire to CTS
No wire to RTS
Absolutely yes.
ETA: the wires for RX and TX were almost twisted together inside the case. Same with GND and 5V. They would have shorted together at the drop of a hat.
ETA2: Apparently the CH340G does support 3.3V operation, but it needs 3.3V power to do it, so there won't be any easy modification of this cable...
