• Loose or damaged switch connection points
• Dim or unreliable headlight control from a failing dash switch

Installation Notes and Tips

Verify connector shape, terminal count, and voltage before installation. Confirm vehicle fitment by year and model, especially for 1984 Ford Econoline and Club Wagon applications built from 3/84 onward. Match the existing dash switch configuration and inspect the harness connector for heat damage or corrosion before connecting the replacement. Standard Ignition DS-690 is intended for direct replacement in the listed vehicles, including 1985 Ford E-150 Econoline and related Econoline Club Wagon models.
