Default Regarding Throttle Body grounding - can anybody explain this?

I am getting a P2100, P1290, P2101 code. Looking at the wiring diagram it seems to show something labeled as NCA (google searches suggest "No Color Available") diagram shows dotted line around the wires from the harness connected to BLK going to Ground. Can anybody explain this notation? Attached screen snap
