Installing Interior LEDs?

[Swikity]

I searched and couldn't really find this.
I'm thinking of buying this product from this website:
http://www.superbrightleds.com/cgi-b...ARS#xFLS-RGB15

I'm going to put it on the interior of my car probably near the pedals and on the passenger side too, I just have some questions.

When I get this, how do I install it so that they turn on when I activate the dash lights (so mostly when it's dark outside)?

I'm a real noob, so please try to explain it in the simplest way possible xD

Thanks for the link, but my problem isn't buying them, it's installing them, lol.
I have no idea how to do it.

if you can wait till tomorrow ill try to give you a few ideas

Yeah, I can wait.
Thanks for the help

power + ground = on

ground + power to switch -> power line out to lights = on and off
