  • 12 V electrical system with 35 A amperage rating
  • Rectangular connector shape with 4 male blade terminals
  • Push-on mounting type for straightforward relay replacement

Detailed Description

The RY-805 is a Standard Ignition engine control module relay engineered for vehicles that require a 12-volt, 4-terminal relay with blade terminals and a rectangular housing. It is used across multiple Mazda platforms, including Mazda 3, CX-5, CX-9, CX-30, CX-50, CX-90, MX-5 Miata, Mazda 6, Mazda 5, Mazda 2, and RX-8 applications, as well as select Hyundai, Kia, and Nissan models. This part cross-references Bosch 0332011007 for the same application.

Compatible fitment includes 2023-2025 Mazda CX-50, 2007-2024 Mazda 3, 2013-2024 Mazda CX-5, 2007-2023 Mazda CX-9, 2009-2024 Mazda MX-5 Miata, 2008-2021 Mazda 6, 2016-2021 Mazda CX-3, 2020-2024 Mazda CX-30, and 2024 Mazda CX-90. It also fits select Hyundai Elantra, Sonata, Tucson, Veracruz, Genesis Coupe, Genesis, Accent, Tiburon, Santa Fe, and Kia Rio applications, plus Nissan Armada, Frontier, Pathfinder, TITAN, and Xterra models where the relay specification matches.

What This Relay Helps Address

  • Engine control relay failure causing no-start or intermittent start conditions
  • Electrical power loss to ECM-related circuits
  • Relay chatter, sticking, or inconsistent switching
  • Faults traced to a worn 4-pin blade relay in the underhood fuse/relay area
  • Replacement needs for Mazda 3, CX-5, and MX-5 Miata relay applications

Installation Notes and Tips

Verify the connector shape, terminal count, and amperage rating before installation. This relay uses a push-on mounting style and does not include a mounting bracket or mounting hardware. Confirm vehicle-specific relay location and compare the existing relay number, terminal layout, and OE reference before replacement. For Nissan applications, check alternator-related compatibility notes listed in the fitment data before purchase.

Quality Assurance

Standard Ignition supplies this relay as a replacement electrical component for common OE-style applications. The RY-805 is built to match the listed electrical and connector specifications for direct replacement use in supported vehicles.
