For what its worth, I've had my harness apart.
Brown wire goes from A on switch thru A in bulkhead, spliced within harness in engine compartment, one wire to tab, one into motor.
Blue wire from P1 on switch thru B in bulkhead, to tab.
Red wire from F1 on switch thru C in bulkhead into motor.
The green wire from F2 only goes as far as the bulkhead.
