Temperature Control Sensor

[stroker]

Been reading about changing temp control sensor on front of engine 91 LS400 and want to try it..When I looked for the connection this morning I could not find it.. I found something on the top of the upper radiator hose inlet connection after I removed the plastic cover but it didnt have an electrical connector on it but it didnt look like just a plug (it had a bright blue top and a small hole in the center) and couldnt find a connector just sitting there. Could this be just a plug and the sensor is buried under there somewhere else? Thanks for your time and expertise.. Bobby
