Thumbnail Filmstrip of 2001-2022 6.6L Duramax Sensor Connector With Pigtail Fleece FPE-HAR-MU-PT-1 Images
The Fleece FPE-HAR-MU-PT-1 is a replacement 2-pin sensor connector with a 4.5 inch pigtail for 2001-2022 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks with the 6.6L Duramax. Heat, vibration and road spray crack connector bodies and corrode terminals, which causes intermittent sensor signals, warning lights and drivability codes. This pigtail lets you cut out the damaged plug and splice in a new one instead of replacing a full engine harness.
Fleece builds these connectors in-house with automated wire cutting and terminal crimping, so every terminal is crimped to the same spec. The same connector is used at several locations across the Duramax family, including the fuel pressure regulator, alternator signal and L5P rear wheel speed sensor. No core required.
Key Features & Benefits
- OE Replacement Connector: Replaces GM connector 13343443 and ACDelco 13384371 and PT2971.
- 4.5 Inch Pigtail: Enough lead to make a clean splice away from the connector body.
- Automated Crimping: Machine-cut wire and machine-crimped terminals for consistent, reliable connections.
- Multiple Uses: Fits FPR, alternator signal and wheel speed sensor locations, so one part covers several repairs.

Vehicle Fitment & Technical Installation Notes
Fits 2001-2022 Chevy Silverado and GMC Sierra 2500HD and 3500HD with the 6.6L Duramax. Common locations: 2001-2016 fuel pressure regulator, 2004.5-2005 LLY injector connector, 2011-2016 LML high side regulator and alternator signal, and 2017-2022 L5P rear wheel speed sensor, alternator signal and fuel pressure regulator.
Installation Tip: Disconnect the batteries, then cut and splice one wire at a time so the pin positions stay matched to the harness. Solder and seal each joint with adhesive-lined heat shrink to keep moisture out.
