Chevrolet Silverado 3500HD Wiring Harness - Fleece Performance - Multiuse Sensor Pigtail No. 11 - 01-16. This direct-fit pigtail is made for GM 2500/3500 Duramax trucks from 2001 through 2016 and restores a reliable connection to multiuse sensors used in fuel and engine management circuits.

Designed as a straightforward replacement for a damaged or corroded sensor pigtail, this Fleece Performance part matches the original connector pinout to simplify repairs and sensor swaps. The pigtail allows enthusiasts and technicians to replace only the connector assembly rather than splicing into OEM wiring, reducing repair time and preserving factory wiring harness integrity. It’s an ideal component for owners customizing or repairing Silverado 3500HD trucks where correct sensor connections are critical.
