I have a VW turnsignal switch in my car, it's a 3 wire switch, and it also has a dimmer built into the back side of the signal lever, and this has two wires for it. Can anyone tell me how I can test this turn signal switch and the dimmer switch as well on the workbench before I install it? It's removed from the car now, and I want to make sure it works before I install it. Please keep it simple as I am an electrical zero!

Is there a better switch for me to use that is more original looking?
