Actually no cigarette lighters in the vehicle - just the outlets.
But I use one outlet for my iPod adapter: low draw.
I'm getting tired of unplugging the thing every time I shut down the engine.
The quick-and-dirty would seem tb to drill a hole in the bottom of the dashboard the size of the adapter and just hard-wire the thing to the same source that the radio is connected to.
A little quicker and even dirtier: wire one of the outlets to said radio source and live with the fact that if somebody forgets and plugs something with a high draw into that outlet, a fuse is going to blow.
Can anybody comment on what seems like the good-right-and-holy path here: namely installing some sort of relay switch so that the cigarette lighter outlets go through the relay switch and the switch is hooked up so it's turned on/off by the ignition key - maybe by just wiring the trigger part of it into the radio source or some dash light's source that goes on and off with the ignition key?
