Mazda 2001-Up Radio Harness

This wiring harness connects an aftermarket stereo to the factory plug in Mazda vehicles from 2001 onward. It carries power and four speaker channels through a single connector. The Metra Electronics 70-7903 eliminates the need to cut or splice original wiring. Installation is completed by matching the harness wires to the new radio.

Installers avoiding factory wiring cuts

The harness suits anyone fitting an aftermarket head unit into a compatible Mazda who wants a reversible, plug-in installation. It is not for vehicles outside the stated Mazda 2001-Up application or for systems requiring more than four speaker outputs. Buyers needing steering-wheel control retention or amplifier integration should look at a different interface.
