I found a radiogram on the street. There are two short wires out the back, both stripped about 1/4" bare, and no plug. With regard to polarity, does it matter how I attach a new lead and plug? I'm in the US and will be plugging it in to 110V. [more inside]

I'm trying to do all the wiring in my house in order to distribute data and voice connectivity to each of the locations to which Cat 5e is run. It's been a while since I've done wiring (last time was probably a college job maybe 15! years ago), and I've got a few questions about how to set this all up. Sorry for the length, but I wanted to be as clear as possible about my current set-up. [more inside]

No dial tone inside my house, but the DSL is working. When I plug a phone directly into the grey box (a.k.a. Network Interface Device) on the outside wall of the house, at the same time disconnecting the link from the phone company's incoming line to the wiring inside the house, I get a dial tone! It seems that the phone company is still providing service. The evidence is exactly what I'd expect if there were a phone off the hook inside the house... but there isn't. What else could be going on? [more inside]

Wiring/music equipment question: I have a fairly cheap 30WVox guitar amplifier with a phone/line out jack on the back. When I plug something into the jack, sounds stops coming from the amp's speaker and starts coming out of whatever I plugged in instead. However, I would like it if the sound would come out of both at the same time. How easy or difficult would it be to rewire the amp so that it works this way? I'm good with a soldering iron, but not too great with circuit analysis.

Apropos of nothing, why would the wiring going to the fog lights on a US 2002 VW New Beetle have an extra unattached plug on it? This is not the lowest model, but came with the fog lights standard. I wonder if one of the upscale versions had fog lamps with two bulbs in each light or something that would have required another plug. On second look, it occurs only on the drivers side wiring, the passenger side looks normal. Please stop me from agonizing over this superfluous detail!
