A test light, voltmeter or continuity meter will show which terminal is which.

Yeah I didn't think the wires mattered which terminal they were attached to due to the design of the switch. I'll probably swap them just to see.

I'll pull it apart tomorrow and see if anything is incorrect inside.

Not really, most hydraulic switches fail quite often and when they do you have to open the system to replace it. A mechanical switch will also light up the brake lights faster and is much easier to replace. I figured utilizing the factory style mounting of a '28-'29 switch and pedal pull setup was the easiest route.
