I got tired of trying to figure out how to wire a water temp sensor correctly so I went to see Todd of J&T Products and he helped me install it. He was a very nice guy who went out of his way to help. So, here is a link to youtube on how to install a J&T Products water temp gauge. It is easy and anyone can do it.
