Bentley should show a number at "end" of ground wire at bottom of
wiring diagram page. Look for this number in ground section on
components page before first page of diagrams.

The AFM figures into operation of FP once engine is running. There is
a (IIRC) switch that gets actuated once air is flowing through AFM.

This page explains how the relays work etc.
