I doubt there's one place they put the cable when they install it at the dealership. Its probably different for every mechanic who does the work. For instance, my Bugeye has the block heater coming out at the bottom of the front bumper, attached in the center. My wife's 06 Impreza has it tucked up right next to the battery, hidden so well I thought we didn't have one until I swapped the battery out.
