I guess the third one is the ground (positive, negative, ground).

I don't think you should have any problem with it.

There is no negative in wiring.

In, out and ground. Better?

@Rest. Thanks for clariying that.

That isn't right either, a light switch has ins and outs of the same wire, sockets have ins and outs of all three wires.

I was just going with what most people think, you know, 1 cable for the current to go in, another for it to go out and the third one for ground.

Just let it go!
