72 inch (6 ft) PMD Harness Extension for 6.5L Diesels

72 in Extension Harness for 6.5L GM Diesel PMD/FSD Relocation 72" extension harness connects the original PMD/FSD wiring harness to a relocated PMD. The length of this extension permits a wide range of relocation options. This extension harness is compatible with all black PMD/FSD units; it will not work with gray PMDs. The PMD (Pump Mounted Driver), also referred to in some instances as the FSD (Fuel System Driver), is the Achilles heel of the 6.5L GM diesel. As such, relocation of the PMD is quite common and relocating options are plentiful. This 72" harness permits PMD relocation to a variety of locations. The PMD/FSD is mounted to the driver side of the Stanadyne DS4 injection pump on turbocharged 6.5L GM diesels. A tremendous amount of heat is generated as it intensifies the signal from the powertrain control module to the fuel solenoid. During normal operation, the flow of diesel fuel is used as a coolant and, in theory, prevents the module from overheating. However, underhood t
