The easiest and most reliable way to determine which wire of your brake switch wire is the correct one to use is to use a circuit tester like part # PTW2993 to test all of the wires for voltage when the brakes are applied and none when released.
It sounds like you are wiring up a brake controller so I attached a help article on brake controller hardwiring for you to check out as well.
