Get in your time machine, go back a few days, take a deep breath, and tell us precisely WTF you want to do. All these electrons have been wasted by the tooth-pulling and hand-waving to find out what you need.
I am going to hazard a guess, and suggest that you use a plain old orange toner, one side connected to ground (yes, Hal, to ground) and the other lead connected to the wire. Then use a plain old Aines probe, and start listening.
Assuming you know the general route of the wiring, and assuming you know roughly where they are supposed to terminate within the walls, you should have no problem hearing the tone.
Telling us that you are disappointed that the fairies haven't surprised you with a solution and hung up your speakers is not going to advance the solution to the problem.
