Alternator charge wire from the ecu to the dash
Can someone help me point what color wire from the ecu that monitor
the alternator if charging or not charging. From ecu to the dash. I need
to know the wire color from the ecu.
I appreciate any help.

I don't know all the details (never had to mess with it) but I believe the S has a slightly complicated charge monitoring system, as it actually measures charge/discharge current via the "Electronic Load Distribution Unit" located in the under-hood fuse box. That's in addition to the 2 wires from the regulator (inside the alternator) to the ECM (wht/grn & wht/red in connector C). I don't think there is a single wire that gives a "go/no-go" signal.
