Ford does NOT service this connector separately, meaning a damaged plug typically requires replacing large portions of the engine harness.

The SWAG Performance 2-Wire ECT / EOT / IAT Sensor Pigtail Harness eliminates that problem by giving you a direct-fit repair option — restoring proper sensor function without unnecessary cost or labor.

Built as a high-quality replacement for Alliant Power AP0056, this connector is the go-to solution for fixing failed or deteriorated wiring at the source.

Replace the Connector While You're Replacing the Sensor

If you're installing a new ECT, EOT, or IAT sensor, reusing an old brittle connector is a common mistake.

Over time, factory connectors become:

• Heat-cycled and fragile
• Oil- and coolant-contaminated
• Loose at the terminals
• Prone to intermittent signal loss

? Replacing the connector at the same time as the sensor helps prevent repeat failures, misdiagnosis, and comebacks.

Common Sensor Applications

• ECT (Engine Coolant Temperature) Sensor
• EOT (Engine Oil Temperature) Sensor
• IAT (Intake Air Temperature) Sensor
• Other Ford 2-wire thermistor sensors

Why This Part Matters

A failing connector doesn’t just interrupt signal — it sends incorrect data to the PCM, leading to:

• Cooling fan running constantly
• False overheating conditions
• Hard starts and poor warm-up performance
• Unnecessary sensor replacement
• Ongoing drivability issues

Since no OEM service connector exists, this repair pigtail is the most efficient and reliable fix.
