Good morning everyone.

I've been searching for awhile but need some assistance.

I have a 2011 2500 6.7 G56.

I recently retired from the military and decided to settle down in a place with emissions (Long story, life happens).

I have a ATS compound setup but, I need to return the truck to stock for emissions.

I did not do a good job marking the exhaust system and what goes where.

I also threw a lot of things away years ago.

The question is, does anyone have a diagram or know where to look to find out which sensors go where specifically on the downpipe (there are 3 sensor positions and I know one is an O2 sensor) what are the other two? I think they are temperature sensors.

Also would like to see a diagram for the rest of the system.

Thank you.
