Step 1: Set Up and Evaluation

Tools I used: Chisel, Hacksaw, Electrical tape (or shrink tubing), wire cutters and/or strippers, flat head screwdriver (preferably sharp-ish and wide-ish), optional: two monkey wrenches for prying. Time: It took me about 1 hour, most of which was spent figuring out how to pry open the adapter box.

Step 2: Break the Box: Getting Into the Adapter

It took many techniques to figure out how to open up the adapter box. The plastic was too weak to crack open w/ just a screwdriver. It just scratched with pressure, while the seam remained firmly bonded. So, I managed to create a deep groove around the entire seam w/ a chisel.
