ECT Sensor Location

Does anyone know where the Engine Coolant Temperature Sensor is located? The diagram in the Manual (SF-62) is not clear and shows 2 wires leading to the sensor. I have found another sensor (but not in the same location) with only 1 wire leading to it, however it does not look at all like the ones on Ebay or some of the parts places where the sensor has 2 terminals on the connection. A pic would be helpful if anyone has one or has replaced one. Thanks.

Thanks, would you know if it had 1 or 2 wires leading to it. The sensor's I've seen for sale have a 2 pin electrical connection and the sensor I suspect it is (in the same location as you indicated) only has 1 wire leading to it. I think the diagram in the shop manual may be incorrect or for certain years, they installed different types of ECT sensors.

Thanks very much! I wasn't looking down far enough past all the vacuum hoses and was looking at the oil pressure switch with one wire. Great photo's. The ECT Sensor is listed (if defective) as a trouble area causing the DTC PO171 that I've been having and cost under 30 to replace. Thanks again.
