Combination Switch Connector for Ford and Lincoln

The Standard Ignition S-1781 is a direct replacement combination switch connector for select Ford, Lincoln, and Mercury vehicles. It is built for electrical repair work where the original connector is damaged, allowing you to replace the connector instead of the full harness.

  • Male connector with female pin sockets
  • 10-terminal, 10-wire configuration
  • 10.25-inch harness length
  • Includes butt splices
  • High-grade copper alloy, brass, and phosphor bronze terminals
  • Polyamide resin housing for durability
  • 100% tested for mechanical and electrical fit, form, and function

Detailed Product Overview

Standard Ignition S-1781 is engineered as a replacement electrical connector for combination switch circuits in vehicles such as the Ford E-350 Super Duty, Ford Crown Victoria, and Lincoln Town Car. It is a gray 10-terminal female combination switch connector application in many listings, with fitment spanning model years from 2003 through 2019 across Ford, Lincoln, and Mercury platforms. This part cross-references Premium Guard PT1284 for the same application.

Built with copper alloy, brass, and phosphor bronze terminals, plus a polyamide resin housing, this connector is made for stable electrical contact and long service life. Standard Ignition S-1781 is a practical repair solution when the original connector body, terminals, or wiring end is damaged but the rest of the circuit remains serviceable.

Common Repair Uses

  • Broken or heat-damaged combination switch connector
  • Corroded terminal connections at the switch harness
  • Intermittent lighting, turn signal, or column switch electrical faults
  • Damaged wiring end on Ford E-150, E-250, or E-350 Super Duty applications
  • Connector replacement on Crown Victoria, Town Car, and Grand Marquis electrical repairs

Installation Notes and Tips

Verify terminal count, connector color, and harness style before installation. Match the connector to the vehicle’s original switch wiring and confirm the application notes for models that require multiple connectors. Use proper crimping and splice practices when joining the included butt splices, and inspect the mating terminals for heat damage or corrosion before reconnecting.

Quality Assurance

Standard Ignition tests these electrical connectors for proper mechanical and electrical fit, form, and function. The materials and construction are selected to support consistent performance in demanding automotive electrical repair applications.
