Hey Tom, there should be a green wire somewhere in the harness going to those sensors, that green wire is the temp sensing wire, if your car came original equipped with the rally gauge option, all you have to do is get a temp sending unit for gauges( not idiot light type) and hook screw it in the drivers side hole on your intake, and hook just the green wire to it, if it does`nt work then then either your gauge is broken or you have a broken wire somewhere on your car,or it did`nt come with the ralley gauge option , if it did`nt come with the option you will have to swap two wires on the instrument pod plug, ( if thats the case I will have to look up to see which wires need to be swapped, Forrest
