What to do with extra DIN slot?

[david_12121]

the car is doing great so far
500 miles gone by with only $20 maintenance costs! way above my expectations you guys scared the sh#t out of me the first time i asked about reliability!:P

so i got my new stereo and now i have an extra DIN slot which i'm not sure what to do with. i don't wanna leave it empty so i was thinking about building/(buying?!) a couple of 12v and 115v sockets for tha slot

has anyone done it or seen one? where can i get a solid electricity cable from? is it possible to build such a thing in a neat way?
