Installation Notes and Tips
Verify connector shape, terminal count, and dashboard mounting location before installation. Match the vehicle’s original push-to-start switch configuration to the Standard Ignition US1439, and confirm fitment by year, make, and model before replacing the part. Because this unit uses a push-on attachment method and a single rectangular female connector, proper alignment during installation is important for secure electrical contact.
