Mike,
1. Aren't you glad the roof was on before the snow came ??
2. Hope you remembered to wire the garage for 120V AC, NOT 12V DC
3. No, you don't need to use Pete's light relay info
4. Be honest with the kid, tell him "My dad would never have let ME move out there", or "trust me, it's for your own good", or just smile real big and tell him "me and mom have plans for the upstairs" and poke him with your elbow a few times
