Temp Gauge/coolant Sensor Again

[tony w]

could anyone tell me if my coolant sensor should have one spade terminal or two.(breg 320i series 2 with m20 engine) my temp gauge doesnt work so i replaced the sensor but it is still not working. the old sensor had one spade terminal but there were 2 wires one was wrapped around the other so only one was connected. i ordered a new sensor onloine and was sent one with 2 spade terminals but it did not fit as the thread size was 12mm and my old one was 14mm and no one can supply a 2 terminal sensor with a 14mm thread. i think someone fitted the 1 terminal one knowing that it would'nt work because they could not getthe right thread size and it kept the car on the road.i defo think i should have a 2 terminal sensor and there are defo 2 wires to connect.i am at my wits end with this so hope someone can advise me .thanks

Tbh Tony, I am wondering if the hole has been re-tapped as I can only find the 12mm 2prong for your motor? Maybe purchase a 12mm-14mm thread adaptor, this would solve it !!
