Where is the ground for the 450 circuit? (L98)

I have a grounding problem for the ECM. I need to know where this ground is located and how it is routed. I got fault 41, 33, 32, and 23. I found that all these sensors (8cyl, egr, MAF/MAP, and ICM) ground through this 450 circuit. It's also the power ground for the ECM.

Can anyone help?
