Automotive cummins 2015 6.7L in a ram

[RickatGL]

I do have insite but it will not work through the OBDII port, I have to find the engine plug. We bought it brand new, 150,000 km, mixed use but around 100,000km of heavy loads like 18000 lb payload. It's doesn't get daily use. Sits alot until we need it.

Im going to try and convince the GM to let me play with the diesels, to fix them and properly maintain them instead of paying shops that don't care about our dime, just their bottom line.
Thanks for the what's what guys appreciate it.

Does anyone know where the ecm hook up on the engine is for a 6.7. That works with insite.

Ok, so I got the go ahead, current issue is my insite 7 9.0 cant connect to the ecm through the obd ii port. However I do have a old obd ii scanner and I got the current codes which is a p003A. Basically out of of parameter. Possible stuck vanes, actuator is not the problem, because when I road test the truck makes almost 30 psi boost. It is not steady like a truck engine. Seems to bounce around from 25-28 under heavy throttle.
Tail pipe is soot free 98%. I swiped it with my fingers and it has a very light off grey color, barely made my fingers dirty just shiny.
Maybe I'm wrong let me know, that's why I like rawze. Provides the matter of fact information you need to hear or what you need to do.
I need to get more involved in the repairs only outsource what I cant handle. Even then I need to know why it's going in beforehand to prevent this shop scam trend.
