CBs (help)

[SOP8920@Siena.edu]

Folks,
     Tonight.. I received my old CB radio from home. I set this up a few years
ago in my vampire like (it refueses to die) old car. That was quite a few years
ago... the set up is simple.. three wires to connect plus antennae. One wire
labeled (+ BATT), one wire labeled (+ switched BATT) and one wire labeled (-
BATT). 
     Obviously, this means one wire to a constant 12v, one wire to a source of
12v that switches on/off with the ignition, and one wire to ground. Since I've
played around too much with the Audis electrical system.. I was hoping one of
you would help me out here. I want the simplest hook up, and don't want to
strain anything. Obviously, go to the fuse box.. right? Which wire to which
fuse? I would prefer to keep all the wiring in the cockpit and not have to 
run a line through  the firewall. 
     As for placement of the magnetic antenna, I think the simplest place to
mount it would be to place it on the rear trunklid. I'm not sure if the roof 
would offer better reception/transmittance quality, but that would mean running
the cable through the door. Ideas.. comments.. help?
