the brake light switch is an "active ground"

put your meter in "beep" mode and press one lead against each contact point on the switch. If it beeps, then you've got an issue. If the meter is quiet, and only beeps when you press the switch; time to move on to plan B.

Another way to test would be to just un plug it and see if the lights go out.
