Here's a website with tips and videos on hot wiring, although I think they make things a little more complex than they have to be. Like I said before, all the simple information on power supplies, tools, gauges of wire, wing jigs, etc, can be found in the first few pages of this thread, but if you would like to see how others are doing it and watch some live video then check out this link...
