Connect Firewire

[rabbit75]

I am trying to connect firewire with front ports. The case wires have are:
VP
VG
TPB-
TPA-
TPA+
TPB+

The motherboard diagram looks like:
TPA1+ TPA1-
Ground Ground
TPA2+ TPA2-
+12V +12V
(no pin) Ground

I am not sure how to connect. Can someone help me?

Thank you

A&B- to 1&2-
A&B+ to 1&2+
VP to +12
VG to ground
would be my guess.
