Wiring Question

In my old grand am, there was a switch that was installed to cut power to the 12v power outlet. This was great because I didn't have to unplug my TomTom every time I turned the car off, I could just flip the switch. I was wondering if this is a good or bad idea, I was considering doing this to my cobalt because, from what I've read, GM products always leave power to the 12v outlets even when the key is off. Thoughts?

So I'm confused, you'd rather wire a switch to turn off an outlet that may not even be powered when the car is off instead of just unplugging the device? Seems completely unnecessary to me.

Why you gotta be making sense and what not.

Adding a kill switch would be simple enough. A SPST would do the trick. You could get fancy and get one with those covers like you see in fighter planes. And a light-up switch so you know it's on.

I just hate unplugging everything all the time. I'm more OCD than the people you see on Germ-X commercials so I hate seeing cords everywhere.

Nothing wrong with adding a switch. Most domestics have constant on the lighter plug, japanese imports have them on the accessory. If you don't run the tomtom with the car off, you could wire a relay to automatically switch the lighter circuit with the key, or hardwire it to the switched radio line.

I would do what ta2 said, or if not at least run the power through a switched 30A relay. The lighter power is one of the highest amperage circuits in the dash and if you ever wanted to use the lighter, the switch alone may not be able to handle the amperage reliably.

doing this and using it to charge something, particularly a cell phone could cause noise in your radio reception.

Maybe if you don't wire it properly. I have my cell dock wired directly into the radio harness to eliminate noise(WHAAA?!)

If you do not want to do the relay (the best option) get a switch rated for at least 10 amps, higher more would be better.

If you do the relay you will not need a switch. You can power the relay off one of your switched power sources so the key will turn the relay on and off.

Just make a kill switch. Completely kill the battery. Then you don't have to plug in your Tom Tom AND you get to make new radio stations everytime.

I'm just being a douche. I have no clue about wiring. Probably my least favorite thing to work on beside body work/interior.
