Rear brake switch

With the help of David at First Kick Scooters, I have come to the realization that my stock rear brake switch was actually one from the Rally 180. It would be in grey with a grey gasket. You can see my stock one pictured here on the right. Note the guts of the stock one. It is in the "open" position, which means when you push the plunger that the connection is formed. SIP pictures their black Rally 180-200 here and you can see the internals are the same as my stock one. So now my big concern is, since I don't use a "Closed" GS/SS180 brake switch, should I have also used a Rally 180 wire loom (if they are different). Anybody know this answer?
