T-Smac

Here are some pictures of the location. Just follow the steps shown on the site EXCEPT: NEVER front probe a connector! You could spread the connector, causing high resistance and thus a lower temp reading in this case. Use a T-pin, or some kind of pin to back probe the connector (slide the pin into the connector from the rear, where the wire itself enters the connector).

If you have a AEM EMS, order the ECT driver for a EMS.

Otherwise you can measure directly at the ECT sensor plug per Modifry's instructions IF you want a custom programmed unit.
