Thinking of replacing your aftermarket harness, then the Xtenzi wire harness is a must for a quick and clean installation. Our premium quality wire harnesses help to install your aftermarket stereo with ease. The Xtenzi harness eliminates cutting your OE radio plug and allows you to reinstall your factory receiver if necessary. After connecting the wire harness, your install is made simple with our E.I.A. color coded wires. Please note these harnesses are designed to be a replacement for the original factory harness. They are only designed to work on Factory radios which are NOT 'factory amplified' or 'premium sound' models. Although they may still fit these radios, we're unable to offer any form of assistance or support when purchasing this for 'premium sound radios' and often times they won't even connect to premium sound radios/systems without additional parts or OEM sound Amplifiers. Made to work as a replacement for select Chevrolet, Pontiac & Saturn models.
