The ECT Module does NOT work on 2006 and newer clusters that have an outside temp display, see example here
The AP2 version works pretty much like the AP1 except it's designed to drive the improved gauge in the newer cars (2004 and up). The original gauges (2000 to 2003) have only 6 active segments; the new ones have 19 active segments. This provides better resolution and more information about your engine coolant temperature.
Here's a comparison between the stock gauge display and the standard Modifry ECT display. The numbers indicate the temperature at which each segment lights up. As you can see, the stock gauge lights the 8th segment for any temperature between 178 and 225, which is a pretty wide range. It also provides readings out to 273° which is far higher than you'll ever see and a waste of gauge resolution.
The Modifry version narrows the "normal" range to between 180
and 205, the temperature encountered in 95% of daily driving. Beyond that
it lights up one additional segment for each 5° above "normal". This
provides earlier warning of an overheat condition without causing undue
fluctuation in the gauge. Plus, now you'll know what the actual
temperature is, not just "I think it's hot". You can see some more
gauge displays here
comparing the stock and Modifry displays.
