The part number S-622 is also referenced in electrical connector interchange listings for related repair applications.

What It Is Used For

• Repairing a melted, cracked, or corroded turn signal switch connector
• Restoring intermittent turn signal or lighting circuit contact
• Replacing damaged blade terminals in the steering column harness
• Fixing wiring issues caused by loose or overheated connector bodies
• Addressing connector failure on Ford Mustang, Ford Ranger, and Mercury Capri applications

Installation Notes and Tips

Match the connector style, terminal count, and wire layout to the original harness before installation. Verify the vehicle’s year, make, and model against the fitment list, since several applications note that multiple connectors are required or that the connector is used in specific steering column configurations. Inspect the mating switch terminals for heat damage or corrosion before connecting the new pigtail.

Quality Assurance

Standard Ignition focuses on electrical repair components developed from long-term research and development, with an emphasis on technician-focused fit and conductivity.
