In the spirit of helping out someone else, here's what PSI Conversions/GM says about the IF and L connections:
Generator F grey wire C2 32 field duty cycle
Generator L brown wire C2 61 Gen L turn on lamp
A voltage regulator is part of a vehicle charging system having an alternator or generator and field winding and connected to a vehicle battery and devices for supplying a voltage and powering vehicle devices. The voltage regulator includes a microcontroller operative for monitoring output voltages representative of monitored load changes within the vehicle. A power output circuit is operatively connected to the microcontroller and connects to a field winding. The microcontroller is operative for changing the field duty cycle of the generator or alternator by turning ON and OFF the power output circuit in a predetermined manner as established by the microcontroller based on monitored load changes.
