As far I can tell, my '57 is all original drive train, interior, and most sheet metal, that switch looks like mine, a 3 wire switch. I mounted single bulb (1157) tail lights along with the fender mounted front turn signals. I wired two DPDT relays and the 2 wire turn signal flasher can. I'll try to find my hand drawn wire diagram.
I can sort out a wiring diagram on my own. Thanks for thr offer though.
My intention is to swap the parking light housings to dual filament bulbs and put in a set of white/amber bulbs for the front. I have a set of Grote housings with brake/turn/reverse lights in them for the rear.
Thanks for the info all.
