I can not find the engine temperature switch that goes to the telltale light on the dash. I have located the temp. sensor that goes to the control mod. and the temp. sensor that goes to the gage, but there must be a third one that goes to the light. When I unplug either of the two I have found, it still does not kill the light. So were is the light switch?

Welcome to AF. Try grounding the single wire connector and see what happens.

I'm sorry but I can not find a single wire connector, both the gage sensor and the control mod. sensor have two wires going to them.

Check the wiring diagrams at this link. http://autozone.com/az/cds/en_us/0900823d/80/0f/40/0f/0900823d800f400f/repairInfoPages.htm
