Just guessing but the old Ford switches were sort of stacked from one end to the other, the switch changed rotation to linear on a plunger. The wire to the starter is on one end that goes to the Start position on the FFR switch. There were two big yellow that go to the B or battery. The brown wires are ACC the pink wires are IGN. The best thing to do is volt meter the wires with the coils disconnected and see what works in which position. Any 12 V Battery will let you test it. HTH, Richard.
