headlights takes like 15 minutes. its 2 bolts and a small nut to crack loose to slide the headlight out of the bracket that is secured to the chassis.
i think you would have to take the pin or whatever (I don't know anything about wiring really) and just run the wire to an area that has power when the ignition is on. Id imagine somewhere thru the firewall to the glovebox, or even a spot in the engine bay.
Someone with more experience will probably chime in with a good spot to wire to. :S
