@Scott - Thanks, I hadn't seen that web page. The pictures are useful. I haven't soldered the wires to the board yet, but probably will ahead of time per the instructions. The board is mounted into the chassis by the time you get to this step, so it shouldn't be very hard to solder the wires to the mounted TO-220 packages.
@Birgir - Thanks for the tip about putting shrink wrap in them. I'll to that upgrade.
