Use to add an aftermarket radio to the factory vehicle wiring.
Standard wire coloring usually will connect color for color to aftermarket radio's wire harness.
Important Compatibility Notes:
All vehicles require you to run a separate 12 volt ignition power wire to new radio since that wire is most likely not available on the factory harness. As long as you know how to locate and connect that wire then you will save some money- if you don't know how to connect then we don't recommend this harness and you should purchase the harness that is about $50+ more that has built in adapter for that wire turn on.
This harness only works with regular factory audio systems- if the factory audio system is the external amplified type like Infinity, Bose, Boston Acoustics, etc then this harness is not compatible.
Will not retain some features that go through the radio like warning chimes, OnStar, rear dvd, steering audio controls, etc.- other adapters are needed for retention.
Most vehicles will need a radio install kit also.
