Product Description
Michigan Motorsports 6.5L Diesel DS Fuel Injection Pump PMD Wiring Harness
Fits 1994–2005 GM 6.5L Turbo Diesel | For Gray PMD Modules Only
This Michigan Motorsports Fuel Injection Pump PMD Wiring Harness is a brand-new replacement designed specifically for GM 6.5L turbo diesel engines equipped with the Gray PMD module. A worn or failing PMD harness is one of the most common yet overlooked causes of drivability issues on the 6.5L platform—leading to intermittent stalling, hesitation, hard starts, or unexpected engine shutdowns. As the connector ages, terminal spring tension weakens and loses consistent contact with the PMD, resulting in unstable communication with the injection pump. Replacing the harness restores a solid, reliable electrical connection and is essential whenever servicing or relocating the PMD.
Key Features
- Direct Replacement Harness: Engineered specifically for GM 6.5L Turbo Diesel engines using the Gray PMD (Pump Mounted Driver).
- Restores Reliable Electrical Connection: Corrects weak or loose terminal contacts that often cause rough running, hesitation, or random shutdowns on aging 6.5L diesels.
- Prevents Intermittent Stalling: Eliminates inconsistent PMD-to-pump signal transfer—one of the most common drivability complaints on the 6.5L platform.
- Essential PMD Service Component: PMD connectors only withstand a limited number of plug/unplug cycles; replacing the harness is recommended when replacing or relocating the PMD.
- Durable, High-Quality Construction: Designed to endure diesel heat, vibration, and harsh operating environments for long-term reliability.
Key Fitments
- Fits nearly all 1994–2005 Chevrolet & GMC trucks and vans equipped with the 6.5L Turbo Diesel and a Gray PMD module.
Note: This harness fits the Gray PMD only.
