About the General Motors Receiver Wire Harness

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

First, attach the color-coded wires on your Crutchfield harness to the wires from your new stereo. If you don't know how to use a soldering iron, we recommend that you purchase some wire connectors that you'll use to attach the Crutchfield harness to your factory harness.

Now, once this harness is connected to your new stereo, you'll be able to plug right into your car's factory radio connector. This harness makes installing your new stereo easier, and allows you to put the factory radio back when you sell your vehicle or return it at the end of the lease. A detailed instruction sheet comes with the harness. Warranty: 60 days.

Please read this important note: This harness may not contain provisions for every wire needed to complete your installation, and it will not accommodate special navigation, video, or factory steering wheel control connections. You will need a special adapter if you want your factory steering wheel audio controls to work with your new stereo.

Connections:

Notes: There are two versions of memory plugs provided by GM, and this harness package includes both types. Your vehicle may be equipped with either one. Discard the unused plug. The 12V constant power lead may not be present in your car. If not, and your receiver requires a constant 12V memory lead (most do), run a wire directly to the battery or an appropriate un-switched fuse.
