!!!before all: please be CAREFULL, you can destroy electric parts.!!!
You have two options for connect BT module to PC.
1) you can use some FTDI (usb <=> serial), with 3.3V logic. Like this
http://www.dx.com/cs/p/ftdi-basic-progr ... UMNiBfdLnY2) you can use cable from spirit (usb pc cable), but you have to add some axternal power (4V - 6V, !!!6.5V is DEADLY for BT module!!!), do you need better wiring?
