Temp Dummy Light - Wiring Help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My Temp dummy light is always on as a default and is getting annoying driving around like that. Can someone explain to me how the dummy light system works on these trucks and maybe how to test the sensor to see if it's faulty or maybe test the wiring?

I'm pretty sure I've found the sensor, it's the one that goes into the head. Looks like I have a gauge sensor near the Thermostat housing. The dummy light sensor I have, only has 1 wire going to it and clipping on.

Why would it be constantly on?

Thanks for any help you can provide!
