Installation Notes and Tips

Verify the terminal count, connector shape, and OE reference before installation. Match the relay to the vehicle’s HVAC wiring layout and confirm the mounting bracket position aligns with the original location. Because this relay is not continuous duty, use it only in the application specified by the vehicle’s HVAC circuit design.
