want to use power windows after key off.

Hello, I am new to this site and I tried to search already and I didn't find any thing. I have a 2006 Ford focus ZX3 and I want to figure out a way to use the power windows after the key has been turned off. I am just wondering if anyone can help me out. I am planning on doing the same thing to the radio using a diagram I found on here. Thanks for any help.

You can do this:

Which allows you to use accessories after turning the car off and until you open a door.

As long as the windows are powered by the accessory circuit (which they almost always are) the relay option will work.  It will also keep anything running on the accessory circuit, such as the radio, operational until a door is opened.

You can also use Kenny's suggestion as well, which will keep the power windows live 24/7 no matter what.  If you have children you may not want to do that because of safety concerns.  You'll still need to do the relays later if you want the radio feature, too.
