Re: Chrysler 75 temperature gauge
They have a thermoswitch on the head that operates a buzzer in the dash, could be orange or white with a single orange wire...but there is a sending unit and guage that works in place of that switch. I think it is an automotive product. You might check with auto parts stores and see what you can find. Also Teleflex makes and sell guages, you might check out their website...just a Thought
