You will first need to figure out what kind of switching the current brake switches are using. Then, you can figure out how to interface with that signal. You say that there is 12vdc on one side of the switch, but when you activate it there isn't 12vdc on the ohter side of the switch? How many terminals does each switch have? Is the 12vdc side still hot when you push the button in (12vdc at all times?)
