Firewire connection to mobo problems

[dantis]

My case IEEE 1394 (Firewire) wires and mobo, Gigabyte GA-8I915G-MF, pin labels do not seem to match up in their definition.

My mobo labels are as follows:
Pin No. Definition
1 Power
2 Power
3 TPA0+
4 TPA0-
5 GND
6 GND
7 TPB0+
8 TPB0-


My Case wires are labelled:
VP
VG
TPA
TPA*
TPB
TPB*
Ground
Ground

So, I am assuming the two grounds to the two GND
Is TPA* and TPB* the positive ones? meaning that TPA and TPB are negative.
That leaves VP and VG which therefore must both go to Power? Does it matter which way round?

I wish they all used the same abbreviations!

Thanks guys

According to my case and mobo manuals which use the same abbreviations: VP goes to a power pin
VG goes to a ground pin next to it
For the TPB, sounds right.
