Ford Stereo Wiring Color Code

If you have recently acquired an aftermarket car stereo and looking to install it in your classic Ford car or truck, then you’ll need to have the basic knowledge of the Ford stereo wiring color code. You may also want to get a wiring harness to enable you to tap into the existing car wiring harness without having to alter or modify the factory wiring.

The wiring harness also makes it easy to remove your Ford factory radio and replace it with an aftermarket unit within the shortest time possible while allowing you to minimize installation-related errors.

When installing a new aftermarket car stereo, you’ll only need to match the color codes of the wiring harness with that of your new stereo. Often, your new color stereo will include a wiring diagram that specifies the function of each wire color as highlighted below;
