Ford Fusion Cigarette Lighter: Re-wire to Turn On and Off with Ignition?
September 4, 2013 4:44 PM Subscribe
I have a 2010 Ford Fusion and a lot of electrical gadgets which plug into the cigarette lighter. The car I previously drove (for over ten years) had a cigarette lighter which turned itself on and off with the ignition. The Fusion, however, leaves the lighter socket on all the time. Because of this, I sometimes forget to unplug things from the cigarette lighter and end up with a dead battery after a day or two with the car parked.
Is there some relatively-easy way for me (or a mechanic) to re-wire the cigarette lighter so that it powers itself on and off with the ignition? If so, how?

*** Pre-emptive answers to questions you might ask ***
1) Why don't you just remember to unplug your stuff?
Probably because the car I drove for the previous ten years didn't require it. I have had this car for just over three years and I still forget to unplug things from time to time, so I need another solution.
2) If you've run your battery down this many times, it's probably shot. You should buy a new one.
Yeah, I know. But I don't want to buy a new battery just to run *it* down repeatedly because of my lack of remembering to unplug stuff.
3) Your "stuff" shouldn't run your battery down in just 1-3 days; something is definitely wrong with your battery/car/etc...
I have had my battery tested by both the Ford dealer and independent auto parts stores, and they say nothing is wrong with it. Additionally, when I do remember to unplug all my accessories, I can leave the car parked for over a week and it starts just fine afterward.
4) What the heck kind of stuff do you leave plugged in that causes your battery to run down that quickly??
My Garmin GPS is enough to make it run down in 2-3 days of being parked. In addition to that, I sometimes also run a cell phone charger and a Globalstar satellite phone from the vehicle power.
*** End Section ***
I am familiar with and comfortable working with 12V electronics. I would prefer to do this work myself, but would probably refer it to a mechanic if it requires extensive removal of dashboard/etc components.
Thanks in advance for your suggestions!
