For my Prius' block heater, I plug the extension cord to the heater into a power strip in the garage (heater is only 400w, so I shouldn't be in danger of burning my house down). A couple hours before I leave, I go into the garage and flip on the power strip, then turn it off right before I leave the house. That way I don't have a live cord at the car that I'm messing with while my hands are potentially wet from snow and ice.
YKYAEM if you find yourself discussing your block heater use strategy on the internet.
