Mate if you remove the trim on driverside centre console, you will see under the radio a unused 3 pin plug ( that on earlier models was a cigarette plug) 1 of the pin will give you +12v from the instrument -parker lights then another +12v and a negative / earth pin.
i got a set of neons and wired it up through the +12 instrument lights pin and the negative pin. and works great and under $30.
use a multi meter to determine the pins (top of me head the bottom pin is earth)
