Cigarette Lighter Always On, Rewire To Different Fuse?


Asked by Jan 17, 2010 at 04:17 PM about the 1997 Ford Taurus G

Question type: Maintenance & Repair

The cigarette lighter in my 1997 Ford Taurus is always on ('hot'). As I use this for my GPS, I would love it, if I turned off the ignition, the power is also disconnected from the lighter socket.

Doing some research, I found out that in the fusebox, the lighter should be connected to fuse 21 / 20A / Integrated control panel, remote entry, cigar lighter.
Now I was thinking, would it be better to disconnect the lighter power-cable from this fuse and connect it to fuse 10 / 20A / EEEC relay,ignition coil, passive anti-theft system, radio ??

If so, what wires should I be looking for and would it be easy to do? I do not have much experience with the wiring in this car (or any car!), so please go easy on me ;o)

Any suggestions would be very much appreciated!

try acrefully opening up the dash and wire in a toggle for that port.


Thanks for the fast reply, however, as mentioned: "do not have much experience with the wiring", so what's a 'toggle' or a 'port' ??

toggle =on/off switch, port = power access (cigarette lighter is the plug) think about your gps. it and the lighter has one thing in common red is hot, black is not.

Again thanks so much for your patience with me and your help, however.... I actually got a good idea from our local oreilly auto parts; The guy there suggested to tap into the power-supply wire from the car-radio (*), as this unit only will be used for my GPS and use a 2nd power outlet for this. Came home and directly went to work on it. Took me about 30 mins to get everything nicely / neat done and it works like a charm! Now I have my (GPS) power outlet turning off when I turn my key off and the original cigarette lighter is not 'touched', leaving it 'hot' and open for it's normal use ;o) (*)Note: My radio has 2 power-supplies: 1 that stays 'hot' all the time for the clock + memory and 1 that turns on with the key only. Obviously, I used that one ;o)
