I am adding leds in the footwells and have put color leds in the dome lights. I like the look when all the interior lights are on. Any ideas on how to hook all the interior lights up to a single switch? Any help would be appreciated and this is in a g35 sedan 03

 

I'm sure you can tap the footwell lights into the switch on your done light. That way they'll go on every time the done light does

 

but id like to be able to turn on all the lights in the car with one switch

 

Sorry meant to say dome*
If you tap it into the dome light switch you can use that switch to turn on the lights
