When you purchase your CD deck, purchase a vehicle-specific wiring pigtail with color-coded wires and a connector plug that will connect to the factory connector that's now connected to your original radio. You simply connect the wiring pigtail that come with the new CD player to your veh. specific pigtail. The deck wll come with instructions and wiring diagrams, and the pigtail for your vehicle will have proper wire markings and instructions on the package/wrapper...
Then just plug your new unit into the connector that was plugged into your original radio... The veh.spec. pigtail will make it super easy.
Good luck...
