The 4th gear switch is only mentioned in the label for the B pin of the transmission connector. The assumption is that one of the switch terminals is connected to ground inside the transmission and the switch is normally open. That might not be the case in a stock '84 700R4, although it was for my '93 model. The following thread includes pages and pages of all the different ways these transmissions were wired internally.
