OK. Thanks. I have seen a 3 wire clamp on, self cancelling pseudo turn switch usually used on Willys. It thru me when you said original. In 57 there was a factory, column integral, 6 wire switch. No relays.
The switch, you evidently have, was not intended to have relays. It was for two separate rear lights on each side. It flashes front and rear left.,,,,and flashes front and rear right. Then, in the rear, you would need another set of lights for Brake and Run. A dual filament in each. The brake is not thru the turn switch like a normal setup. That same self cancelling switch is available as a normal 6 wire.
In order to only have one light on each side with that switch, you use relays. As you have done. The DIY wiring diagram for that is quite ingenious. I have it somewhere.
