Product Description
Michigan Motorsports 6.5L Diesel DS Fuel Injection Pump PMD Wiring Harness
Fits 1994–2005 GM 6.5L Turbo Diesel | For BLACK 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 BLACK PMD module. A weakening or worn PMD connector harness is a very common cause of intermittent drivability issues on the 6.5L Diesel—often leading to stalling, hesitation, hard starts, and unexpected shutdowns. Over time, the terminal spring tension inside the connector relaxes, causing poor electrical contact with the PMD. Replacing the harness restores a proper, stable connection and eliminates one of the most overlooked failure points on the platform.

- Restores Injection Pump Reliability: Ensures a clean, stable electrical connection for reliable engine operation—critical for older 6.5L applications.
