One thing to note, in the EVTM only the circuit you're investigating is shown.
Connector 'C123' may have R/O/Y on the fuel pump circuit, and on a totally different page 'C123' may reappear with G/B/P on the tail light circuit.
Both are C123, but 123 is a six wire connector with two distinct circuits running through it....
Jeff is good to point out that the connector bodies are also shown.
