CUMMINS ISB 6.7, CHECK ENGINE LIGHT??

hey everybody,
we got a 2016 yard goat with a cummins isb 6.7, came in for a def metering module code that was coming up as shorted or open circuit, traced all my lines from the ecu to the module and found continuity between the 5v power line and ground, which indicated a short somewhere in the harness, since i wasn't sure where in the harness it was and it would be a pain in the ### to find, i decided to run my own power and ground from the ecu to the module, two grounds and a power, i left the communication lines alone, i attached the diagram and what's been replaced on it so y'all have a better understanding too. once i had everything ran i, i checked resistance and continuity and everything looked perfect, upon restarting the unit, it immediately had the check engine and stop engine light on, i scanned the system and was coming up for even more codes related to short circuitry, see attached, i've rechecked my connections and everything looks good, i have no idea what it could be since the components have issues are unrelated to each other and only joined up at the ecu which is where im assuming the issue is. Only other thing I’ve noticed is every component that is shorted high runs on 5v, internal ecu resistor issue?common ground or power? internal ecu fault? programming issue? bad harness? any help appreciated, thanks

ECU was removed and def module was disconnected when I found ground with power, I’m referring to a harness ground, I don’t have the original printout but it was def metering module short and that’s it and a protection derate, now that I think about it it might be an internal ecu issue sending higher voltage what do u think

 

I don’t think I bypassed anything, my pin locations were fine because I checked continuity from the def module connector pins to the ecu connector pins before I made any cuts to make sure it was the right line, all I did was cut the wires after the pins on each side (ecu to def module) and run my own wires in between.
