I want my radio to turn off with the key.

I want my radio, windows, and whatnot to turn off when I turn the key off rather than when I open the door. Is there a way to do this?

[NYC F-350]

Sure. Every time you turn the key off, open and close the door.

Thanks lol. I would like it to go off when the ignition is shut off because of the turbo timer. If the turbo timer shuts the truck off the radio will stay on for 10 minutes since there's no one around to open the door haha.

So far it hasn't had any negative effects but still, I'd rather it just turn off when the truck shuts down.

You could turn the radio off before you get out of the truck.

[Razorsedge]

I could, but I'd rather it turn itself off haha.

You could run a new 12V wire to the radio that loses power when the key is off.

I could go for something like that.

Does anyone happen to know which wire supplies power to the radio until the door is opened?

Found this on the web. I think you would want to replace the light green/pink wire but it would be worth checking with a volt meter first.

From my car stereo wiring experiance my guess would be that it must be the Black/Violet wire. The constant should never turn off, since it supplies power to keep your presets and clock memory.

I will check into it though, I would need to find a switched power source that doesn't rely on the door opening to cut power.

Thanks for the info on the wires.

Your right it would be the switched power wire.
