6.6L Duramax Diesel Glow Plug Controller FIT 2001-2005 Chevrolet Silverado 2500 3500 FIT GMC Sierra 2500 3500 97304030
Description
Vehicle Compatibility Matrix (6.6L Duramax Diesel ONLY): FIT 2001-2005 Chevrolet Silverado 2500 HD / 3500 HD (6.6L V8 Diesel) FIT 2001-2005 GMC Sierra 2500 HD / 3500 HD (6.6L V8 Diesel) Note: Not compatible with 6.0L or 8.1L gasoline engine variants. Note: Specifically designed for LB7 and LLY engine generations. Technical Specifications & Physical Evidence: Component Type: Diesel Glow Plug Control Module (Electronic) System Voltage: 12V DC / Current Rating: OE-Calibrated Amperage Output Housing Material: High-Impact Heat-Stabilized Polymer Composite OE Part Interchange: 97304030, RY-1556, 97379635, 12450365, 8973040302. Technical Installation & Ignition Integrity Protocol: This glow plug controller is a high-precision electrical hardware component. For successful integration, the glow plug wiring harness must be inspected for resistance signal loss before mounting the new controller. Ensure the electrical pins are free of debris to maintain a closed-loop signal interface. This hardware provides a direct-fit solution to restore factory-specified pre-heat feedback and volumetric electrical load balance across the diesel ignition loop.

- FIT 2001, 2002, 2003, 2004, 2005 Chevrolet Silverado 2500/3500 HD; FIT 2001-2005 GMC Sierra 2500/3500 HD. Specifically engineered for the 6.6L Duramax V8 Diesel (LB7/LLY) engine platforms. Note: NOT for gasoline-powered models.
- This Glow Plug Controller integrates a high-current solid-state relay and a heat-stabilized internal circuit board. The hardware features a sealed multi-pin interface designed to maintain a closed-loop electrical feedback system for the pre-heating geometry.
- The hardware is engineered to address erratic pre-heat signal feedback and mechanical signal lag in the ignition loop caused by relay terminal oxidation. This module restores factory-specified glow plug duty cycle characteristics and maintains proper current geometry during cold-start sequences.
- Each unit undergoes load-tested validation for thermal expansion stability and amperage retention. The high-temperature polymer housing meets OE specifications for acoustic decibel limits and vibration damping, ensuring consistent signal feedback under extreme under-hood heat loads.
- Plug-and-play installation for factory-style wiring harnesses; no software reprogramming is required to maintain signal integrity. Includes the main controller unit with integrated mounting eyelets. Replaces OE# 97304030, RY-1556, 97379635, 12450365.
