Step 3: To the cigarette lighter!
Find a way to get to the power and ground wires using your cigarette lighter. My ash tray just popped and slid right out. It did take some force, yours may use screws or involve taking a part of the dash off. If you do not want to use the cigarette lighter, you can run a line from the battery with an inline fuse, or find another 12v source such as the wire off your cd/tape player. Although these lights hardly draw any power (I have left them on for 2days with hardly any battery drain), make sure you know how to change a fuse if you need to.
