: This might be what I need to do. I don't know about a signal tracer
: kit if its something to carry around and look for signals behind a
: wall, without opening up the wall, that is what I'm looking for. I
: haven't come into contact with anything like that to date.

In the early 90's I bought a wire tracer "pen".  It ran on a single AAA 
battery, looked like a rectangular laser pointer, had a metal tip.  I bought 
mine at All Electronics for a few bucks, Radio Shack had them as well for 
more.

I found I could sweep a wall and locate a "hot" wire behind sheetrock, 
plaster, et cetera.  I would press the button, then "sweep" the tip across a 
wall and watch for a red LED on it to illuminate.  When it did, I could 
sweep more slowly to narrow down the inch or so it would light, then make a 
faint pencil line.  I would then connect the dots, so to speak, to have a 
map of the wire behind the wall!
