42RH / A-500 in a Duster with pictures.

for the time being I wish to just hook mine to a toggle. the connector from the trans has 3 wires coming out. how do I determine which wire goes where? do I hook both the overdrive and the lock up to the same toggle to work at the same time? trying to get this car finished in time for mopars at the strip lol. time is slipping by way to fast :)
