Wiper Motor Wires
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.
Also, when I ordered a new wiper harness from Year One (I think) it only comes as the 4 wire set up and it is completely different. I think it was 'spliced' at the motor connector.
I took it apart and patterned it after what was originally there.
