T-2,
I agree it looks that way, but the publishers are sometimes not very clear in their linking of circuits in the diagrams. Look at the little dashed box connected to Splice 502, labelled "Exterior Lights." A subsequent sheet shows the connections in that otherwise innocuous little box.
The connection from terminal G on the CC module shows connection to the CHMSL. I had this happen on a '96 Lumina and chased it around for a while before discovering this.
