Does anyone have anymore information or a photo for the exact installation location
for the ACC Outside Air Temperature Sensor?

I removed the Left Headlamp, again, to have a second look, and played with the full length of the wiring loom, extending it full length in different directions to help determine possible installation sites, to no avail.

Normally these are just visible (or invisible) in the very right hand side of the lower part of the front bumper vent opening when looking from the front.
