Key Features

  • Standard Ignition RY1975 relay for 12-volt systems
  • Push-on mounting type for straightforward relay replacement
  • 4 male blade terminals

Detailed Description

Standard Ignition RY1975 is built for vehicles that use a 12-volt relay with blade-style terminals and a push-on mount. This relay is used in electrical control circuits where consistent switching performance matters, including blower motor operation. It is a practical replacement choice for 2013-2020 Subaru BRZ, 2017-2020 Toyota 86, and 2013-2016 Scion FR-S models. If you are searching for a Subaru BRZ relay replacement, Toyota 86 blower motor relay, or Scion FR-S electrical relay by part number, RY1975 is the catalog reference to use.

What It Helps Solve

  • Blower motor not switching on or off correctly
  • Intermittent electrical relay operation
  • Heat-related relay failure in the control circuit
  • Loss of power delivery to the relay-controlled system
  • Fault tracing when the original relay shows wear or contact issues

Installation Notes and Tips

Verify terminal layout, blade style, and 12-volt system requirements before installation. Match the relay position and connector style to the original unit, since this part uses no connector and 4 male blade terminals. Confirm vehicle application by year and model before replacing the relay in a Subaru BRZ, Toyota 86, or Scion FR-S.

Quality Assurance

Standard Ignition supplies replacement electrical components for service use, and RY1975 is listed with OE cross-reference numbers for the same application. Confirm fitment against the vehicle’s original relay specifications before installation.
