    eficonnection 24x LT1 cam/crank sensor wiring question NO spark

    I am confused. Tried to fire engine yesterday and I am not getting spark.
    Harness was from 96 LT1, but I added wiring for cam/crank/coils from an 02 truck.
    Wiring checks out, checked every single one, end-end.
    Injectors/coils were swapped for firing order change.
    Bank assignments changed for firing order change.

    I have it wired per GM diagrams on cam/crank sensors.

    A google search seems to indicate eficonnection says pins A&C should be swapped on both cam/crank sesnors.
    Hoping this is my issue? But why would it be different/required?
