What are people doing with the G72 IAT Sensor?

Specifically for 1Z/AHU conversions (and maybe ALH?).
I imagine in some swaps the stock intercooler piping can be used but when custom piping is fabricated how are you guys installing the G72 manifold air temperature sensor?

I have 2.25" aluminum piping with a FMIC, and while this works great my G72 is currently zip-tied to the intercooler. How can I get it in the intake air path?

Most of us have converted the stock ecu to using an external MAP sensor which usually have four wires, two of which are IAT (G72). Requires some modification to the ECU board/cover, nothing too difficult though. Plenty of later style MAP/IAT sensor flanges available.

I did convert to 4-bar map, but used an internal sensor.
The A4-style IAT sensors are compatible with the 68-pin ECU?
