YEP.......cooling fan switch. It grounds one "leg" of the fan-relay coil (the other leg is powered, I THINK by the ignition sw). There are two other temp senders ~ namely, one for the temp gauge (located at the rear of the block on the L/H side, just below the h/gask), AND another for the ECM (top/center in the lower intake, screwed in straight downward). <thumbup>
