You don't need any other switches, wires, etc. All you need is a pair of wire cutters and a little bit of electrical tape. Just cut the specified wire (MAKE SURE IT'S THE RIGHT ONE!) and tape them off. If you want lights during the day again, just turn that knob to the left of your steering wheel!
I also find DRL's useless. But I do leave my lights on during the day. Luckily the Tacoma (and the 01+ 4Runner. Maybe 99-00's, too) has an "idiot proof" feature that turns off the lights automatically when you open the door, so that the "idiot" doesn't drain the battery in the middle of nowhere.
