I have a minor problem on my 420SEL; need help with ID of the parts/connection involved. There is a small metal stud right above my thermostat area that sticks up and a black plastic fitting with a metal part inside that goes down over the engine stud. There is a wire sticking into the plastic fitting, but I don't know what the actual connection is supposed to be. My engine temp is not registering at the dash and I want to get whatever part(s) required to read and transmit the engine temp correctly .... can someone help me with this?? Thanks, Ben Carter
