Front parking sensors location

Good morning everyone,
I am the new owner of a 2022 Tundra SR5. I have a question about the front parking sensors that monitor the left and right front corners of the truck. Are they located inside the rectangle above the license plate (#1 in the picture), in the little circles (#2 in the picture), or someplace else? Anyone know?

 

Never mind......
It's amazing what cardboard, duct tape, and crawling around on the driveway will do for testing-out sensors. The rectangle (#1) is a forward sensor. And so are the little round ones (#2). They monitor the front corners of the truck. After I covered the little ones with cardboard, that truck did not wanna move forward and every forward alarm was screaming at me. I took them off and all was well.
