[RFI] Tracing wires.

[Gary Smith]

That's pretty much what I'd like to find. With that, I could trace 
the wires to everything I need to.

One bugger is a fan in the attic, it doesn't work any more but I have 
no idea it that's because it is damaged or because there is a remote 
switch to turn it on/off. Can't see the wiring because of that damned 
paper mache insulation covering everything 1' deep in paper fiber.
