Bluetooth Replacement Gone Wrong?

DJ, since im having issues with win8, I decided to pull out my usb to serial adapter. it does 3.3 or 5v. I tried 3.3. I attached according to how labeled on my board.
Starting from pin closest to power connector it is RX,TX,GND,V+
I smelled hot resistor after a couple minutes so I unplugged everything and checked the underside of the Bluetooth card. Starting from same reference its labeled VCC,GND,TX,RX.

little beauty in my collection however I don't have it hooked to my ez-b. It's going to my arduIMU V3. It should be well capable of connecting with the EZ-B,.
