Installation Notes and Tips
Installation of the Standard Ignition RU-661 blower motor resistor requires removal of the old resistor from the HVAC housing. Since the resistor uses a bolt-on attachment method and includes mounting brackets, ensure bolts are securely tightened to prevent vibration issues. The rectangular female connector with four cavities must be properly aligned with the vehicle’s wiring harness. Note that no wiring harness or additional hardware is included, so retain existing components for reuse. Verify the blade-type male terminals are clean and free of corrosion before connecting to ensure optimal electrical contact.
