Product Details

The Standard Ignition TS-489 is a round, plug-in engine cooling fan switch with two blade terminals and no wiring harness, bulb, or mounting bracket included. Its open-at-idle design and 12-volt rating make it a practical replacement for cooling fan control circuits where the original switch has failed or become inconsistent. If you are comparing TS-489 against other cooling fan switch part numbers, this unit cross-references 815077 and FS219 for the same application.

Use this Standard Ignition TS-489 when you need a direct electrical replacement for cooling fan switch service on vehicles such as Honda Civic applications that call for this style of connector and terminal layout. It is built around the listed switch geometry and connection style rather than a universal fit.

What It Helps Fix

• Cooling fan that does not switch on at the proper temperature
• Intermittent fan operation caused by a worn electrical switch
• Fan circuit issues related to damaged connector terminals
• Incorrect fan control from a failed toggle-style switch mechanism
• Replacement needs for a corroded or heat-damaged fan switch housing

Installation Notes

Verify connector shape, terminal type, and voltage before installation. The TS-489 uses a plug-in connection with a round male connector and blade terminals, so the mating harness must match that layout. Confirm the original cooling fan switch location and electrical specification before replacing the part.

Because fitment data is not provided in the catalog record, confirm application by original part number and connector style before ordering. For vehicle-specific searches, compare the TS-489 to the removed switch on your Honda Civic or other listed application by connector and terminal configuration.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management components. The TS-489 is cataloged with OE-style interchange references, including 815077 and FS219, to support accurate part matching during repair.
