antec 1080amg front panel firewire setup

[vital]

I'm trying to install the front-mounted firewire port of my Antec Plus1080AMG case to my Asus A7N8X-E Deluxe mobo. The Asus manual says I need eight pins, but the Antec lead only has six. The data cables TPA0+, TPA0-, TPB0+, and TPB0- are easy enough to match up. I only have one grounding wire off the port, which I can simply attach to any of the three ground pins. However, the mobo has two +12V pins while the case's port has only one. Does it make any difference as to which +12V pin I put this on? Will the presence of only one power lead make less power available to the port? My Firewire cable has LED's on them that light up when connected and it does light up when I connect them, but I'm not getting anything when I turn on my external firewire hard drive though.

Does your drive work if you plug it into the PCI-slot-plate firewire outlet that the mobo came with? Does your drive draw all its power from the port by design, or if not, it has its power transformer hooked up, correct? 😱

Yeah it's working with the Firewire slot that came w/ the mobo. My external enclosure is powered by a transfer/ac outlet.

Then my thought would be mostly, could the data pairs be hooked up incorrectly. Here's a way to do an end-run around the problem if nothing else works out: SXFW Cable to connect your front circuit board to a standard FW port. You'd either loop this out the rear and plug it into your mobo's FW outlet, or take the mobo's PCI-slot outlet, undo it from the PCI plate, and plug it in internally.
