Hi larry I think it is the reverse light and start inhibit which go to a 4Way plug on the Rh side of the box near to the shift linkage.

Regards

Registry
Very, Very, common transmission made by the german company ZF. Used in all 1980> BMW 3,5,6, and 7 series up until they went to the 5 speed auto's. Some of the higher spec cars had the EH or electronic handling which changed shift points and offered a normal, sport, and economy modes. It was used in the Ranges Rovers from 87-95 and Disco's to 99, as well as Jaguar XJ 6's and XJS, Maseratti's and some Porsche's. There are litterally a million of these transmissions out there. I have put clutch packs and torque converters in a bunch of them and they are easy enough to work on. If you google ZF 4HP22 you should be able to find out more than you want to know.
