You need two wires, one supplies the power, the other is the ground. Yes it
is as simple as installing a switch and connection to the fuse box. The
second wire is the ground. You can ground it to the door itself, although
it is not a real good idea to send the current through the hinges, although
over the long haul it probably won't do squat. VW runs a second wire back
to the body and grounds it there.
