Convert always on lighter sockets to switched?
I have a 2004 VW Passat wagon, it has four (cigarette lighter) power outlets. Two in the cargo area in the back, on on the back of the arm rest for the rear seat passengers, and the lighter outlet in front. All of them are powered on all the time, even when the car is off, and the keys are removed.
I suppose this was seen by VW as a convenient way to allow smokers to light up, and run accessories without needing the to get in and turn the key. The life of today's active geek with lot's of portable electronics, GPS, etc. This is not the most desirable configuration.
I'd like to figure out how it would be possible to convert any one of the four outlets to be switched to the ignition key. Any tips, hints, or better yet specific instructions would be most appreciatd.
