Map lights

The courtesy lights will probably be more difficult. Far as I know there isn't any prewiring into the doors for them, so you'll have to run a wire from a dome light feed someplace, fusebox might be easiest, and run it into the door and to the light. I've had those lights in for like a year and still haven't bothered with wiring them up.
