  • Even though it’s “just a three-wire assembly”, in power scenarios red/black/yellow do have specific meanings. On a standard Molex(-style) power connector, there are four wires: red is +12V, two black for ground, and yellow is +5V.

    I agree with you of course, you can use the cable for whatever you wish, but I think it’s also important to realize that in certain applications those colors do have specific meanings. :)

No public wish lists :(
