Also don't forget to add a fuse !
Although less common these days, I have seen portable 12v devices where some
exposed metal was connected to the negative power input. For example, I had
a portable CD player where the metal ring around the headphone jack was so
connected; which of course would make it hot relative to the car body (on a
positive ground car).
Some "marine" lighter sockets come with isolation already built into the
mount, plus a handy rubber plug for when they are not in use.
