Engine side harness for early 2 speed only has three wires but the unused green wire from the F2 terminal to bulkhead is present.

For automatic transmissions, power for the back up light switch (white) goes to a two cavity connector next to the steering column. Both wires on the switch are violet. Power to the reverse lights from the switch connector is also violet.
