    This is a few things I found whilst trying to make a (6pin to 4pin)
    firewire cable, i.e. soldering two connectors to the ends of a wire.

    There are diagrams of the plug pinouts easily found on the web.
    The ones I found are all quite clear. This is deceptive.

    **The plug is female and the socket is male**

    Miss this fact and you will short circuit the power provided through
    the 6pin plug!

    (In my case the fuses on the firewire card did nothing at all, and a
    trace on the motherboard burned through, luckily this was easily
    repaired.)

    **Pair A is connected to pair B at the other end**

    Discovered by trial and error. Without crossing over the wires nothing
    will happen.

    Hope this helps [person like me] searching in the future.
