LarryB's P-Pump Fuel Solenoid Wiring Harness For Flat Pin Solenoids, Includes Relay, Link
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 continuously. This harness has the Dodge plug and fits our Dodge flat pin fuel solenoids. Leads are approximately 36" long.
Four connections are required:
1. Black-- Ground
2. Red-- Battery positive, 12v+ 50amp minimum (50amp min, battery or alt)
3. Blue-- 12v+ when running, ignition on.
4. White-- 12v+ Start power, only when cranking.
