Flash-all 999 turn signal switch wiring

My 1955 F100 has a Do-Ray Lamp Co. "Flash-All 999" 4 wire turn signal switch. Wires are red, black, green & yellow. I am converting to 12 volt and need help on the wiring for this switch.

The switch is not hooked up and therefore I do not know how it was wired. The red and black wires are attached to a flasher with another cut red wire coming from the flasher. My guess is the cut red wire goes to power and the green and yellow are for the right and left side.
