How do I add LED strips to my interior?

Trying to add some led strips underneath the dash of my 03 GA GT1. If anyone can tell me a good location to look under the dash and colors of the wires, that would be awesome.:smokin:

Before you do that, remember that the led strip is not road legal. if it's on while you're driving you WILL get a ticket.

As to which wire, I suggest the accessory/blower wire at the ignition, it's a big orange wire.

For ground, just find a screw that go to the body, or install another one.

I was going to add them in to the interior lights. Like when you open the door they illuminate the floorboard under the dash like in a 2000 Grand Prix. Or when I turn on the dome lights.
