chrysler 300 factory radio replacement

Hi, I'm kinda new to this, but I am trying to change my factory radio for an aftermarket. I bought a wire harness, but it seems like the wires don't match even if it fits in. Here is a picture of my harness. https://scontent-b-ord.xx.fbcdn.net/...eb&oe=537093E7 As you can see, some wire such as the red one (Power ignition) doesn't even match...) When I start up my car, my new radio doesn't turn on, no power Need help, thanks ! __________________

There is not a switched wire at the radio in that vehicle. The radio is turned on and off by a data signal from the car's computer. If your Cigarette lighter goes on and off with the key, connect your radio's red wire to the wire of your cigarette lighter. If your lighter is always on, open the trunk and move the fuse for the lighter. There is only one fuse in that box that has 3 points of contact. Move it over to the other position.

It worked !! Thanks a lot !!
