out of that?

If your PLED cable has 3 pins, note that the middle one is an empty/
dummy plug. It just makes it easier to plug in since you otherwise
would have two 1-pin connectors (also found in some cases).

black & white switch 2 pin Can I assume that white is gnd?
red & white hdd led 2 pin Can I assume that red is positive?
purple & white reset switch 2 pin Can I assume that white is gnd?

White should always be ground/negative unless someone has messed it up.
