Antenna adapter for Mazda tuner-brain models

This Metra 40-HD10L antenna adapter connects an aftermarket radio to the factory antenna system on Mazda vehicles from 2014 onward that locate the tuner brain in the passenger kick panel. The 48-inch harness bridges the factory connector to the new head unit without cutting the original wiring. It restores FM and AM reception after the original radio is removed.

Installers fitting aftermarket stereos

Technicians replacing the factory radio on 2014-up Mazda models with the kick-panel tuner module will find the correct plug and lead length in this adapter. Vehicles without that specific tuner-brain layout, or installations that retain the original radio, do not require this part.

48-inch lead length for kick-panel routing

The harness measures 48 inches, which is the critical dimension for reaching from the dashboard opening to the passenger-side kick panel where the factory tuner brain sits. If the routing path in a particular vehicle demands a longer or shorter cable, this adapter will not suit the installation.
