Some of the neons have a switch located on the cigarette lighter adapter, others dont come with a switch, but most neons have a cig lighter adapter. If it doesn:t, it:s pretty easy to wire them, you just tap the red or black/white wire into a power source, and then tap the black wire ionto part of the metal chassis to complete the ground. There are also control modules that you can plug the neon wires into, which is what I used, it controls up to 20 neons. I was able to squeeze in 20inch neons in front, and 15inch neons under the seat, so in the larger 6th gen sedan, you should be able to do the same. Heres how it looks. . .
