Engine Cooling Fan Switch Connector for GM Applications

Standard Ignition S-733 is an engine cooling fan switch connector built for GM cooling system repairs where the original connector has heat damage, broken terminals, or poor contact. It is a pigtail assembly with a male connector body and a female blade terminal, made to restore a secure electrical connection at the fan switch circuit.

Key Features

  • Engine cooling fan switch connector for electrical repair
  • Male connector with female blade terminal design
  • Single-wire pigtail assembly for targeted connector replacement
  • Built with high-grade materials for strong conductivity and consistent contact
  • Standard Ignition S-733 for service on many Chevrolet and GMC trucks, vans, and SUVs

Product Details

Standard Ignition S-733 is engineered for technicians replacing damaged cooling fan switch connectors on a wide range of GM vehicles, including Chevrolet Silverado, Tahoe, Suburban, and GMC Yukon applications. The connector is designed to restore the electrical path at the engine cooling fan switch, helping maintain proper fan control signal transfer in vehicles with auxiliary fan control or engine-mounted fan switch setups. This part cross-references Edelmann 70007 for the same application.

Common Repair Uses

  • Broken or heat-brittle cooling fan switch connector housing
  • Loose terminal fit causing intermittent fan operation
  • Corroded or oxidized electrical contact at the fan switch
  • Damaged pigtail wiring during cooling system service
  • Connector failure on Chevrolet Silverado, Tahoe, and GMC Yukon cooling fan circuits

Installation Notes and Tips

  • Verify connector style, terminal gender, and wire configuration before installation.
  • Match the existing fan switch connector on the vehicle, especially on 1996-2000 Chevrolet and GMC models with black and blue connector notes.
  • Inspect the mating switch terminals for heat damage or corrosion before connecting the new pigtail.
  • Use proper electrical repair practices to ensure a secure, low-resistance connection.

Quality Assurance

Standard Ignition supports this connector with decades of electrical parts development focused on technician needs and OE-style repair solutions. The brand uses high-grade materials to help maintain peak conductivity and reliable connections in demanding underhood environments.
