Verify the connector shape, terminal count, and mounting style against the original relay before installation. This part uses a 1-connector, 5-terminal blade configuration with a 12-volt rating, so matching the vehicle’s original relay specification is important. Confirm whether the application is equipped with automatic air conditioning where noted in the fitment data. Standard Ignition RY-23 is also listed for Chevrolet Chevette and Chevrolet Camaro applications, so checking the exact year, model, and HVAC configuration helps ensure correct placement.
