We are goin ghetto here, but we still wanna be safe, so an enclosure is a must. I snagged this little aluminum gem for $1.29 at Pacific Valley Electronics. The molex connector is for the 12v-in.

With the help of my trusty "Shack" hand nibbler, I was able to do a decent job of adapting the box to the power plug.

We'll need some pins crimped to the 12v-in leads so we can plug it in...
