Its actually a green/black stripe wire. It is the connection point on th main harness for an optional oil temp sensor at the bottom of the engine case, which feeds a signal to the optional oil temp gauge in the center console of 1973-76 cars.
marvellous, thanks Jeff, I have the loose end of a wire coming off the oil temperature sensor and the gauge in the centre console
I'll connect the 2 and see how it goes
