Can anyone tell me if the sensor I have circled in the picture is the temp sending unit for temp idiot light on a 68 GTO. The light does not come on when I turn the ignition key like the “gen” and “oil” lights do so I want to make sure it’s working. If that’s it, any advice on testing it?

Thanks..... but what do you mean “ground out” the wire connector? Just disconnect it from the switch and run it to ground?
