In-Dash Head Unit Installation

This page is dedicated to the basic istallation of an In-Dash Head Unit. We will cover wiring color codes, wiring connections, Installation Kits and any pictures if available. Most color coding has been universalized for car stereos over the years making installation easier. However, vehicle manufactureres have not yet adopted this practice.  Although Vehicle Power (red), Ground (black), illumination (yellow) Dimmer (orange) have been universalized,  color codes for speaker wires and other functions have not. These could/will vary from vehicle maunactuer.  

Color codes: Head Unit (vehicle color wiring may be different, check your vehicles manual) Or, a source with the info.  If you are unable to locate a source or info on the wiring color codes for your vehicle, let us know and we will be happy to get the info for you.  Visit our " Contact Us" page and send us an email (including what vehicle you are looking for),  we will get back to you in a timely manner.
