I would be interested in doing this as well. I remember my first cellular phone back in '91 was one of those they mounted in your car and it stayed on 24-7. I don't know how it was wired, but I miss that! I'm cheap and still have a bag phone, so I have to have the car running or it doesn't work.
The sockets are controled by Relays.
The relay sockets use the same type pints as the common "blade" type connectors.
It is easy to pull the relay and jumper the switched contact pins.
The trick is getting the right relay, and the right pins.
I have been asked this question enough times recently that I will pull out the manual and get an answer.
I did it a different way by pulling in a new hot from the battery to under the dash to run my stuff.
So that your battery isn't dead when your kids leave the Nintendo plugged in and turned on all night.
Yes, most cell phones will go a whole day or more on charge now. But if you kept it plugged into the car, and the charger was hot, it would recharge in there at night and you wouldn't have to remember to plug it into the AC charger!
For an alternate view, I'd like to say that I love the fact that the power outlets go on and off with the ignition. Much nicer than having to remember all the time to turn my radar detector on and off. Plus, my detector has a very flimsy and difficult power switch--now I never have to touch it.
The only problem I've had in this respect is when I was on a long road trip, every time I'd stop for gas and switch the car off without thinking about it, I'd hear, "DAD! You just turned off my game! Now I have to start all over!" After a while I learned my lesson and remember to have them save before I shut it off.
The relay that controls the front 2 power outlets also control the radio and NAV or DVD.
The relay that controls the rear 2 outlets only controls those outlets.
Youwill need to look at the ETM in person, or have some one with much better explaination slills tell you how exactly to find the relays.
Once you find the relay, you will see it has two large pins and 2 small ones. Just make a jumper that replaces the relay and jumpers the two larger pins. Once you see the relay it will be obvious.
I would bet the dealer could point the relay out to you when you are in for other service.
