Question on the S-Video AV Cables For the Elite 360?

I'm going to provide this link to properly ask my question and give you guys a visual.

Ok do you guys see the 3 primary colors from which you connect your 360 to your tv? Alright well what is that wire that doesn't have a color assigned to it. It's just gray and has the metal tip at the end?

Now I'm taking a wild guess and saying that particular cord, connects to the back of the Elite. Am I right?

Cause I only have 3 holes on my tv for the av cables, and one hole for the headphones. So it can't be another connection for my television set.

I know the Elite can be played on a regular SDTV but I'm just checking to confirm that.

For those of you with the Elite does the metal tipped wire need to be connected?

Or will it still work with just the Yellow, White, and Red chords connected to my tv.

Ok the Elite comes with HDMI, Component Cables, and S-Video cables.

Now upon looking at the component cables correct me if I'm wrong, but all those colors don't need to be connected right?

I mean all I need for my SDTV is the regular yellow, white, and red then I can play correct?

This is giving me a headache since I'm trying to sort this out.

Wait I think probably just solved this mystery question I'm having.

To connect your console to your standard TV:

Ok so basic setup of yellow, white, and red on the tv.

Alright so it's the component cables that are my main focus. Meaning that the other cables will just be left hanging.

Guys for those of you that have read this and for future readers, I apologize if I stressed you out. I am a noob at the 360 since I don't own one. And I'm just trying to learn as much as I can about it.
