Chassis speaker connection

[Qu9ke]

Okay, I know this is very trivial, but this has me curious. On my motherboard, the first speaker connection is +5v, and the fourth speaker connection is "speaker. This leaves the middle two as dummies or whatever. I get all of that. What I don't understand is that I have read many times from people that the red wire is the 5v wire, and the black is the "speaker" wire. I look on a different website, and it says to attach the red wire to the fourth pin and the black to the first. This is the exact opposite of what I took people to be saying. I don't have much reason to use to use the speaker anymore currently (didn't work anyways when I first booted), but I would like to clear up this confusion.

Frankly, unless your speaker has extra electronics that cause it to be polarized, it doesn't matter. It's simply an electromagnet, and polarity isn't relevant.

Generally, you can consider a black wire to be ground, and any colored wire to be positive, or signal, unless otherwise specified (not including house electrical wiring.) If you're unsure, read the manual for the particular motherboard you're working with, but you'll probably find that most motherboard front panel pin headers are pretty much the same.
