Prepping for the plug!
At the cord end:
There is a little channel that runs through the cord. Split that down the center to a length of approx. 1.5 inches
With nippers or electrical wire strippers peel the plastic off of each side of that channel now to reveal the perty little copper wires. When using nippers or the electrical cord strippers don't cut too deeply. The idea is to keep all or dang near all the wires. (and if you notice you can see I've twisted the wires- that's next. see below)
