In a 2005 ford mustang base cluster does it have the MyColor thing?

The 2005 Ford Mustang does not feature the MyColor system, which was introduced in the 2007 model year. The base cluster in the 2005 Mustang has a more traditional design with standard gauge lighting, and the customizable ambient lighting options were not available until later models. If you are looking for customizable color options, you would need to consider a 2007 or newer Mustang.
