Unlock Function

Pressing unlock position on either door lock switch sends a voltage signal to door lock relay terminal "F" (White wire). Pressing unlock position turns on unlock relay located inside door lock relay assembly. Unlock relay completes circuit that supplies voltage to door lock relay terminal "E" (Tan wire). Tan wire is voltage feed to actuators. At this time, lock relay is not energized. When lock relay is off, terminal "B" (Gray wire) is grounded, which provides a ground path to door lock actuator. Entire action described completes electrical circuit to actuators in each door, thus unlocking doors. Polarity of voltage to actuators has reversed, causing actuators to run in opposite direction to unlock doors.
