firewire connections

I am assembling a unit in a case that has firewire ports.
The selected board does not support firewire, only USB.
I purchased a PCI to IEEE 1394 firewire card that has an internal port and interface connection.
The case’s wiring for the firewire is 6 single wires. The interface connection is 6 pins, but they are marked 1, 2 & 3 down each side. The case wires are marked TPB(+)&(-), TPA(+)&(-), VG, and VP.
Can someone point me to documentation as to how to connect these wires?
