Radio Wire Harness and Antenna Adapter. 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. Antenna adapter to connect aftermarket radio plug to the vehicle's antenna connection. Important Compatibility Notes: Will not retain some features that go through the radio like factory rear dvd, aux input, backup camera, steering audio controls, etc. Very Important- All vehicles require you to run a separate 12 volt ignition power wire since that wire is not available on the factory harness. The new radio's red ignition wire needs to be connected separately to the vehicle's ignition wire which might be a cigarette lighter power wire, etc. As long as you know how to locate and connect the ignition 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 $40+ more that has built in adapter for that wire turn on. Not compatible with factory amplified stereo systems. Only works with factory standard systems (no JBL/Synthesis, Bose, etc.).
