A-Premium multifunction turn signal switch for Ford/E-Series and Taurus — 21-pin direct-fit, wiper & washer control

A-Premium's multifunction turn signal switch replaces your factory lever to restore turn signals, high beams, wipers and washer control in compatible Ford and Mercury vehicles.

When a worn or faulty stalk leaves you without reliable turn signals, headlamp dimming or wiper control, this A-Premium multifunction switch offers a direct-fit solution engineered to match the look and operation of the original equipment. Built to the same layout and markings as OEM units, it mounts near the steering column and uses the original connector layout so most owners can swap it in without specialty tools.

What functions does this single lever control?

The A-Premium multifunction switch consolidates several controls into one OEM-style stalk so you can manage lighting and windshield systems from a single position. It handles turn signals and lane-change flashes, headlamp high beams, hazard flashing, and windshield wiper/washer operation.

• Turn signals and lane-change indicator
• Headlamp high beam (dimmer) operation
• Windshield wiper speed and intermittent control
• Washer pump activation and hazard flashers

Which vehicles is this switch compatible with?

This replacement lever is specified for a range of Ford E-Series vans and select Ford/Mercury sedans from the mid-2000s onward. Check vehicle year and model carefully against the fitment list before ordering to ensure connector and bolt-on placement match.

• Ford E-150, E-250, E-350 and E-450 Super Duty (selected years 2005–2019)
• Ford E-150 Club Wagon and E-350 Club Wagon (model-specific years)
• Ford Taurus (2004–2008)
• Mercury Sable (2004–2005)

How close is this part to the original OEM unit and how hard is installation?

Although this part is aftermarket, it has been designed to mirror the original lever’s appearance, markings and electrical layout so it behaves like the factory component. Installation is straightforward for anyone comfortable removing the steering column shroud and unbolting the old switch; no specialized equipment is required.

• 21-pin connector and single-plug design to match factory wiring
• Bolt-on attachment — standard hand tools needed
• Same indicator marking colors and lever ergonomics as OEM

• Operating voltage: 12V
• Terminal count: 21 pins, one plug
• Mount: bolt-on near the steering column
• Includes indicator marking colors matching factory layout
