Lets say I'm connecting the hard drive activity led, should the white wire connect to Pin 1 or pin 2? or maybe the question be is the white wire on each connector the - or + connection? The motherboard I'm connecting to Intel® Desktop Board D865PERL.
Did your case come with a wiring diagram? It should tell you which is which. Do the white wires have a black stripe running down them? Do the coloured ones? (The stripe is usually used to indicate negative.)
Failing that, you could just try hooking them up and seeing if it works. Case lights draw such little power-- in my experience, it doesn't really matter which way you hook them, up. So long as current is flowing thru the LED, they work. (Try this at your own risk! For all you know, it could cause you computer to kerplode. ;-))
