So I have to replace the M50 coolant temp sensor with an E30 one. On the thermostat housing of AN M20 ENGINE, which one of the sensors do I need? And on the M50 head, is it the sensor nearest to the rad support or nearest to the firewall? Thx guys!

Im about to do this too. Its on a m50NV and its going into a 1991 318i.

The answer is on the E30, the connector has two pins in the connector core, but one of them is unoccupied.
