I am trying to debug/fix turn signal wiring on a '53 3100 my wife just bought. It uses a Signal Stat 800. I have found great information on wiring these devices here on the site, but those all refer to original factory wiring on the Signal Stat switch. Unfortunately, a previous owner changed the wiring going to the switch and I have no idea which terminal on the switch is which. Anyone happen to have a key to this or a photo of the color coded wiring on the terminals?
