Need help connecting case cables!

[Scaper]

I'm trying to connect my case panel cables to my motherboard. I do not know which cables are positive, negative or neutral. My case is an Asus Vento A8 and has no manual. Motherboard is Asus P5QL. All parts were bought in the UK.

This is an overview of my motherboard and me holding some front panel cables:

These are the cable schematics:

The only labelled + - cable:

Hard drive indicator LED cable:

Power Switch cable:

Reset Switch cable:

Help much appreciated! The cable colours are really confusing me for which is positive, negative, or ground, especially the reset switch.

black is usually ground. What I go by is, the printed sides go up.

P-LED shouldn't be a problem.
