I know this is going to be a dumb question to some of you but... I want to put LEDs under the dash on the driver and passenger side. To keep everything concealed and neat I'm wondering what to do about the switch. The interior LED light switch located to the left of the steering column "rolls" to increase light and then clicks. The only thing I see different when I turn the switch all the way up til it clicks is that the screen for the radio gets brighter. Is there a prong on the back of that switch that I can use to feed power to the LED strips that I want to install so they'll come on just when the switch is turned all the way up (where it clicks and won't turn anymore)?
