1949 Plymouth Suburban. Have checked my manual wiring diagram and for the rear lighting there is a left tail light and left turn signal, a right tail light and a right turn signal. Then there is a single brake light shown in the center of the wiring diagram. This I'm guessing is the single light mounted on center of the trunk of a sedan, coupe, etc. The suburban has no center light mounted on the center of the tail gate. So my question is where was the brake light/lights on a Suburban or Station Wagon?
