Easiest way to do this.
Run a positive wire from the battery and splice it in with the..........pink or orange wire to the headlight switch. Now i say splice because i tried just connecting it, and it didnt work, so i spliced it and it did work. Now considering im not sure on which wire it was, Buy a haynes manual, or have one of these wonderful folks hook you up with a headlight wiring diagram. (btw, the headlights are also ignition controlled (least in my 91 regal), so they may not turn on while the ignition is off.)
