I suggest you install the new coolant temp sensor in the spot where your old one is at. If you want to keep the functionality of your HOT / COLD dummy light then all you have to do is go to Radio Shak and get a simple logic circuit. You would need a circuit to apply ground or 12V (whichever was switched by your old sensor) to your original temperature lights based on the voltage of the new coolant temp sensor. It sounds complicated but you should be able to find something like that at Radio Shak or on the internet.
