Here are the tools you'll need:

Razor knife or Xacto
Step 1: Preparing the cable
First, cut a ten foot length of your 12/4 wire and strip off the outer jacket. You can discard the jacket as you won't need it at all. Use masking tape to make sure that the twist of the cable stays the way it is.
Next, strip the ends of all the wires back about three quarters of an inch. In my case, I had red, white, black, and green coated wires. You will use two wires for each "leg" of the cable. So, twist the ends of the red and white wires together. Do the same thing for the black and green ones. The red/white will be the positive leg and the black/green will be the negative. Once you've got them twisted together, tin the ends so they'll stay that way while you're handling the cables.
Next, find the center of the wire (5 feet from either side) and cut the positive leg. Strip back the insulation where you just cut, combine the wires and tin them the way you just did with the ends. This center cut is where you will later add one of Transparent's "networks."
