From what I have seen (I have never used it either) there is a plug and wire (I think you usually need to intstall your own plug and wire) and it is necessary to use a rheostat or even better, a thermostat when dealing with heat tape. If you are going to use those mini chests, make sure you don't put the heat tape on the part of the drawer that overlaps with the plastic structure of the chest. I would also use the 3 inch heat tape, and make a heated section of about 6 inches wide. After that, just drill some holds in the front and side of the box, put down a layer of paper towels, a humid hide, and a petri dish for water and you are good to go.
