When removing a factory radio and replacing it with an aftermarket radio, you will need to use a wire harness or interface.
Wiring harnesses allow you to make color coded connections without modifying the factory cabling and connectors . Some vehicles require the use of an interface*; an interface prevents vehicle errors, provides full integration to factory equipment (Amplifiers, Steering wheel controls) when removing the radio due to factory data-bus systems.

When installing an aftermarket receiver you will match the functions of the aftermarket wire harness with that of the aftermarket receiver. The wire colors of your new receiver may, or may not, match the wire colors of the aftermarket harness.
The aftermarket harness will include a key that indicates the wire color and function, you will match these with the aftermarket radio harness by function. These connections must be soldered and insulated to prevent accidental shorts. Insulated crimp connectors are also suitable.
