Amuse front bumper diffuser install question
 

I have the Shine Auto Amuse front bumper, sides, front diffuser, TS rear diffuser, and Amuse type 2 wing sitting in my garage.

Been searching, but all the pics on where to cut the bumper are no longer active. I know the general area, but having a pic for reference would be useful. In addition, if anyone has pics they could post of their front bumper and front diffuser install, I would greatly appreciate it. Not just the front of the car (I have dozens of those), but underneath would be helpful. I'm doing the install myself.

Thank you.
