Not really. You really have to hook everything up and just start adding holes as needed. I started with like a row along the top of the back of the tub (since mine are in a rack) and just went from there. Every time I needed to add holes I would do about four or five at a time. I use a soldering iron to make the holes since a drill can crack the tub.
