Cool that's pretty much what I want.just a book or two, phones and tv remote ect. Wired in my stereo and cig outlets and usbs yesterday to a fuze box and it all worked!
Not sure if it matters, I'm probably going to do my roof first so if I forget any wires in the walls I've got longer to think about it! Are you using a flush trim router bit to trim the roof sheet or profiles? That's probably might have some bearing g on witch you do first
