When relocating the pump mounted driver “PMD” onto an intake mounted cooler this eight inch extension harness makes the job easy. When the injection pump was installed the wire harness may have been routed in a way that causes it not to reach the new PMD on the cooler, or the original PMD was a black color and the new PMD is gray. If this is the case the black wire connection is different than the gray and this extension harness will work as the adaptor to make it work with the gray PMD.
This harness extends the factory wiring harness between the GM 6.5L diesel injection pump and a remote mounted PMD (pump mounted driver) 8 inches. This harness uses the Stanadyne gray style ends found on gray colored PMD's. This harness can be used with the older black style Stanadyne PMD with slight trimming on the PMD plug end. This is the correct harness if your stock harness will not reach the PMD on a cooler mounted to the intake manifold.
