Cummins Bosch P7100 fuel solenoid connection harness. Perfect for replacing bad wiring, engine conversions and modifications. This harness is designed for easy connection and control of the fuel solenoid on the Bosch P7100 injection pump. This pump is used on many models of the Cummins diesel engine. The solenoid has two circuits, one for the run (hold) position and a stronger one for the start (pull) mode. A relay is required for the start mode because the solenoid draws 45+ amps and will overheat if this circuit is used continiously. This harness has the Dodge plug and fits our Dodge flat pin fuel solenoids. Leads are approximately 36″ long. Four connections are required. 1. Ground, 2. 12v+ 50amp minimum (battery or alt), 3. Run, 4. Start.

Received this and the item had different color wires than the instructions said – called up Larry on the phone number provided in the box and got it all figured out. Just an issue with obtaining the right colored wires due to COVID backups up on the manufacturing ladder! Very helpful YouTube videos, too.
