    Default turning off accessory power outlets when truck is not running

    does anyone know if there is a way to keep power from running to the accessory power outlets when the truck is not running? i have my gps plugged in and i dont want the battery to run down. i wonder why gm's power outlets keep power all the time but toyotas and nissans dont.

    my 03 dakota also was auto controlled, well the one by the cup holder under the dash, the one in the center console was constant powered. Worked out well for my application!

    Now the 07 silvy...bah, just got it last week and have yet to look into it but its on my very long list of "things to do to the truck".

    If you're that worried about it, just unplug it...

    BTW, it won't draw as much power as say the radio's memory.

    yeah i have been unplugging it but just wondered if there was a way to turn it off like turning off the change oil light by pressing the gas pedal 4 times or turning off the auto headlights by pressing the dome light button 4 times or whatever. thought maybe i could stand on my head and rub my stomach 3 times and touch the power outlet 3 times or something like that and get it to turn off when the engine is off lol

    It wouldn't be very difficult to wire a relay in the circuit to have it work automatically. Of course, as soon as you do that, you'll wish it were back the old way.......:sarcastic:

    You'll have to rewire it.
    Or add an aftermarket plug thats fed through a keyed hot from the fuse box.

    Just a thought and Amy you might be able to help with this since you just did your lights could you use a relay like folks use for their driving lights.
    Make it where if there is no power on the one side then the other circuit is off also like you cant turn on your driving lights unless your highbeams are on.

    Wouldnt even need to cut anything just make some jumpers with spade connectors I would think.

    Ughm...............well..........I really don't know.

    All of my lights are wired seperately with fuses and relays, I never splice into the factory wiring ever. I don't see why you can't just unplug the GPS, to each there own I guess. good luck with that.
