Turn signal wiring

I bought a used turn signal switch.  It doesn't have any markings on it, so I don't know what brand it is.  It has 7 wires. My question is, how do I figure out which wire goes where?

found this but I learned real quick when I was changing the style of switch on my truck that a handful of alligator clip jumpers was my best friend. I got to make sure everything worked as ir should before making any connections permanent.  https://diagramlibrarymps.z21.web.core.windows.net/57-chevy-turn-signal-wiring-diagram.html

Can you include a picture? Maybe someone will recognize the brand. Also you might search eBay for a look alike that may have the brand name. Then you could google for a wiring diagram. Worth a shot.

Most seven wire switches are similar in regards to wiring. Wire colors may vary somewhat but the functions are pretty standard. I found this article to be informative. https://www.restore-an-old-car.com/add-turn-signals-to-an-old-car.html

The one I bought is similar to the diagram that is linked above has.  Before installing mine I hooked it to a 6volt lead and bench tested it with a series of four bulbs.  This way I confirmed it worked and that all of the listed colors were correct.

Make certain too the correct flasher relay is used.  NAPA EL 550 was found to work correctly in my install efforts.
