As Tom W. said, you have part of the 1st switch that used a bail. You need the correct terminal block and wiring harness to use this switch; this switch only has 3 positions: 6= off, 7=Park, 5=On, you have no high beam as the headlight blubs are 21-3 candle power. Your headlight reflectors would be single blub, and you would have small headlight conduits and the headlight glass would be fluted, you should also have the tuna can taillight which was used thru March 1929.

If you have a later switch and wiring harness you can modify the wires to the headlights by using the green and park wire to serve your headlights, cut off the red wire so the two remaining wires will go through you conduits.

The switch will have park at 7, off at 6, high beam at 5, and nothing at 4.
