Dragon 2 & Case Firewire pins

My case has frontside USB and Firewire ports. I was able to hook up
the USB ports. However, I am having a heck of a time with the
firewire.

My pins on my chassis are labeled:

VG
VP
TPA+
TPA-
TPB+
TPB-

In my manual, it lables the headers as:

1. A1PC
2. GND
3. B1PC
5. PWR1
6. A1MC
7. CGND
8. B1MC
9. PWR1
10. CGND

My BayOne manual has a different labeling system. But either way, I
am totally confused here. Can anyone provide some help?
