That's cause yours is a 2009+. Puddle lights didn't come to the 04-08's until like 07-08. Anything under that will have to be wired for the puddle lamps. There is a how to on here somewhere, I know is a wire in the loom under the drivers side panel and is light blue and black towards the bottom of the bundle if I'm not mistaken!
