I actually know the feeling of trying to find the right switch. I wired up some underbody and grill lights on my Jetta a little while back (they looked phenomenal but unfortunately I ran over a tall speed bump and snapped the wire), and we got them wired into the circuit that controls the headlights and it worked seamlessly well. But... it took many long hours to find the right wiring and switches for it.

Do you have a collection of cassettes at all? I remember them quite well from my childhood and they are pretty nostalgic. Nowadays CDs are the new cassettes.
