Ty for the info, don't have truck at house at the moment or I'd check on that.

- update -
Took truck to a dealer shop today (I've took it there before and they seem to give me an ok price on labor/parts since I financed it through them, plus I need to get it back on the road asap to get some money coming in) - They checked fuses and plugged up to the j1989 connector on the engine harness with cables ran for it's own power and ground and weren't able to connect with the ECM so I'm not sure but it's looking like another ECM is gonna be needed... Not sure if cummins will give me a refund or not since I didn't get them to program it (big oof on my part) They said they'd test some other stuff on monday to confirm it is the ECM. If it is I'm just hoping there is a way to make sure it doesn't fry the next one... I mean 2 ECMs going bad doesn't seem like a coincidence, plus if it was a factory dud the guy I took it to that programmed it would've probably noticed something.
