vp44 cummins stand alone wiring help

Recommended Posts

I am wanting to do a 24 valve cummins swap into a truck and i was wanting to know if a factory wiring harness could be modified to work without the original truck. I have been told that the 98.5'-00' trucks and the 01'- 02' have slightly different wiring. My question is has anyone done a stand alone wiring harness or does anyone have a diagram of a factory harness that has been turned into a stand alone harness?

You need EVERYTHING from the donor truck.  You cannot make a 98-00 truck run a 01-02 motor or the other way around without everything.  

 

They have different wiring, different ecm flash, and different sensors.   More involved than wiring changes.

 

do you have a 98-00 truck or engine?

yes its a 2000 truck.

i am wanting to put a 46 dodge 1.5 ton body on a 2000 4wd 5 speed frame and running gear.

sorry about not being clear on that i want to be able to run the vp44 24 valve without being in a 2nd gen dodge. i did a search on 24 valve stand alone wiring and found a guy on youtube who had used the original wiring and modified it to be stand alone. he had a link to a site he had found the wiring diagram but i tried to access it and it had been deleted.

Cummins used to make and supply the Dodge techs with a stand alone pigtail that would let the engine run at idle with the VP plugged into it.  We have talked about it here before but I don't have the details on it.  

So it is possible, but finding that info might take a while.  I never put a ton of work into it.  

it would be possible to make a stand alone harness, just pull everything out of a truck and rig it on a test stand with some batteries.  However, I don't know if it is worth the hassle unless you plan on test running a bunch of engines.

well i like the idea of being able to put a vp cummins in an older vehicle. it might not be worth doing but if its possible and not EXTREMELY involved i think it would be a fun project, most cummins swaps i know of are mechanical injection. i have seen a buick riviera that has a 24 valve with the vp44, i don't know if it has an original harness or a painless harness.
