60250 - 2003-2005 Cummins Diesel Engine Harness 5.9L - Manual Transmission Only

  • $900.99


Take a look at just some of the great features we have designed into the 60250 harness.



The first aftermarket harness to facilitate the transplant of a Cummins diesel engine, this harness will fit 2003 - 2005 5.9L common rail diesel Cummins engines using standard transmissions.  Professionally manufactured by Painless Performance with all new components that meet factory specifications for durability and performance this harness is the product of an 18 year tradition of Painless ingenuity.


Created with a rugged Bussman weatherproof electrical center at its heart, this harness is ready for the harsh environment of a diesel engine compartment.  Integral fuse block circuits include 40 amp relays for fuel pump, fuel heater and ignition circuits.  B+ and ignition circuits are short circuit protected by the 10 mini ATC fuses.




Built with pneumatically crimped, gold plated terminals for a positive connection between the PCM and all of the engine sensors. 


Internal harness wire splices are pneumatically crimped and then sealed with weather proof heat shrink.


Extra 20 amp fused output wire included to power anything from a CB radio to a water methanol injection system.


Connectors included for all three styles of accelerator pedal position sensors. These three types being; 2003 bell crank mounted to the front of the intake manifold, 2004 APPS factory mounted under the driver side battery tray and 2005 APPS mounted to the accelerator pedal inside the cab.




Have a bad sensor; find out which one is causing your problem by retrieving diagnostic trouble codes and live engine data through using the OBD2 connector that is wired into the harness.  You will notice we don't have a check engine light attached to the OBD2 connector pictured to the right.  Chrysler builds their late model trucks with a digitally controlled check engine light.  The ECM does not have a driver to turn a light on.  Instead, it communicates serially to the instrument cluster control module which controls the check engine light.



Got a 2003-4 Cummins and ECM but want to run an aftermarket lift pump; no problem.  The 60250 harness gives you the ability to operate a 40 amp relay (pre-mounted and wired into the fuse block) with a 2003-4 fuel pump drive circuit from your ECM.  It is as simple as swapping one inline connector to the next.  See picture below.
