How to test turn signal switch

[767Jockey]

OK, I've got five wires coming out of this thing. Two are fairly thin and are both brown. I assume they are likely the momentary switch wires for the button located behind the signal stalk. The other three wires are heavier. Two of them are identical, both are black with a white stripe. The other one is the same thickness, but plain black in color. I am assuming that the black one is the common, or "wiper" as Ron calls it. The other two must be what will become the Left and Right signal depending on which I hook up to each individual side, no? Does this kind of make sense you electrically savvy guys?

One last question, if I remember correctly, in the originals, wasn't the signal switch installed bass ackwards, with the stalk pointing toward the passenger side rather than the drivers door side as is standard here in the US?
