Keep switched power flowing to your engine's management circuit with the Standard Ignition Computer Control Relay (RY-1580), a direct-fit Mazda 3 relay for the 2005-2009 Mazda 3 and the 2007 Mazda CX-7. A relay is an electrically operated switch — a low-current control signal closes the internal contacts to feed a higher-current circuit — and this unit is cataloged with a Main Relay function.

  • Built to last: a high-quality composite housing helps it stand up to the heat and demanding conditions found under the hood.
  • Certified quality: produced at TS16949- and ISO9001-certified facilities to meet high industry standards.
  • Wear resistance: brass or copper contacts, where specified, help extend contact life in high-stress use.
  • Specs: operates on 12 volts with four male blade terminals and a rectangular connector.

A mounting bracket is not included. Country of origin: Japan. If a failed main/computer control relay is the cause of your no-start or intermittent power issue, this replaces it — diagnose the circuit first.
