Need 12Volt AC wire for 2002 300M

I'm looking to install an XM Satellite radio into my 300 M.  I want to wire the unit directly into my dash with a 12 DC Accessory Outlet and wanted to know what wire is the correct one to tie it into?

I was hoping to have it power up with the radio and power off with the radio.

Any help with the correct wire and wire color would be greatly appreciated.

Thanks.

I need to know what color the switched 12V power wire is for the radio on the 2002 Chrysler 300m.

Also, there is no ground strap, rather a black wire coming from the radio.  Is the black wire GROUND, or is it a different color.

Thanks.

does that black wire have a little plastic slide-on connector on the end? (see the first page of this pdf file)  if so, then it's definitely the ground wire.  Course you can always verify this using a multimeter.

if you still have the factory plugs, you can just use a wiring harness and save yourself a lot of trouble.  If the factory plugs have been cut, then you really are going to need to use a multimeter to verify the switched power wire.  Usually it's the pink or pink w/white stripe wire, but for safety reasons you should verify this before making the connections.

Just a note, the wiring info in that pdf file is mostly irrelevant to your vehicle, with the exception of those diagrams of the grounding connector.
