My zxt has two sensors in the thermostat housing. Which one is for the temp. guage and what does the other one go to? They both have one wire sticking out, and there are two cut wires that I think connect to them. I know one is for the temp guage because I ground it and the guage goes all the way up. Any help is greatly appreciated. I don't like driving around not knowing how hot my engine is. Thanks.
