At a Glance

• Helps reach remote-mounted factory tuner or radio module locations
• 48-inch harness length for added installation reach

System / Wiring Notes

• Use only when the Axxess Vehicle Fit Guide or installation instructions call for an AXEXH extension harness
• This is not a stand-alone radio replacement interface and must be paired with the correct compatible Axxess interface
• GM RPO codes and factory radio configuration must be verified before purchase

Exact Vehicle Compatibility

Find your vehicle below, then match the model year and factory-equipment details in the same row. Factory radio, amplifier, navigation, trim, speaker location, and connector differences can change which installation parts are required. If anything differs, contact MCOR before ordering.

Fitment note: Year and model alone are not always enough to confirm compatibility. Match every factory-equipment qualifier shown for your vehicle, and contact MCOR Automotive if the radio, amplifier, navigation, speaker, camera, trim, or connector details are uncertain.

Installation Notes

• Confirm exact vehicle year, model, trim level, factory radio system, and option codes before installation
• Additional installation parts such as a dash kit, antenna adapter, steering wheel control harness, or radio-specific adapter may be required
• Professional installation is recommended for best results
• Check current Axxess instructions before installation and update firmware when required
